Asteroids in astrology are used to identify highly specific themes, events, abilities, relationships, and psychological patterns that the traditional planets cannot always describe in detail. Their interpretation requires more than associating an asteroid with its name or mythology.

Asteroid Astrology Research Since 2002

Reliable meanings must be tested through discovery charts, exact aspects, biographical cases, historical events, and repeated chart comparisons. Astrologer and author  Benjamin Adamah started his investigation in 2002. His ongoing research covers approximately 1,000 asteroids, centaurs, trans-Neptunian objects, and related minor bodies. This article is based on his personal expertise and many years of testing. Asteroid astrology is based on a relatively young field of research. This means that many finer points are still being refined, while a more reliable consensus continues to develop and will continue to do so.  So far our research, at VAMzzz Publishing VOF, is based on the analyses of 750,000 data pages – each containing about 50 lines of aspect data, created with serennu.com and astro.com, and thousands of discovery charts and test charts.

The greatest value of asteroids is that they do something the traditional planets cannot: they increase the resolution of the horoscope! The planets provide its fundamental architecture; carefully selected asteroids reveal the finer details.

Do Asteroids Really Work in Astrology?

Yes. Asteroids can add an extraordinary degree of precision and detail to a birth chart. It is also difficult to justify the assumption that only the largest planets, the Sun, and the Moon should be astrologically significant. Size alone has never been a consistent criterion in astrology, nor has distance. Pluto, after all, is both small and extremely distant, yet few modern astrologers would dismiss its importance on those grounds alone.

From a broader metaphysical perspective, ideas found in process philosophy—particularly the work of Alfred North Whitehead—also challenge the notion of a universe composed of isolated objects acting only through simple, linear causation. Modern physics likewise gives us little reason to assume that reality must conform to an intuitive model in which only the largest or nearest bodies can be meaningful. This does not mean that quantum field theory proves astrology; it means that simplistic objections based solely on size and distance are philosophically inadequate.

In practice, some relatively small asteroids can be remarkably important. Eros, for example, can describe with great specificity where passion, desire, fascination, and creative intensity are concentrated in a person’s life. Its sign, house position, and especially its close aspects can reveal dimensions of desire that are much less obvious from the traditional planets alone.

Juno is equally valuable in relationship astrology. It can indicate the qualities we seek in a committed partner, the type of partnership in which we are most likely to thrive, and recurring themes involving commitment, loyalty, equality, and power within relationships.

The real question, therefore, is not simply whether asteroids work, but which asteroids are astrologically significant, under what circumstances, and how they should be interpreted without overloading the chart.

Mouth of Orcus | meaning of Orcus in Astrology

Orcus Mouth. Like Pluto, Orcus-Vanth is a binary Plutino. Orcus measures about 917 km in diameter and Vanth measures about 276 km. Orcus was discovered on February 17, 2004. The planet is named after the Etruscan underworld god Orcus while Vanth received the name of the psychopompus (soul accompanying demon) Vanth. Orcus at the core is about keeping the “fundamental oath” to ourselves (What do we really want with our life) in contrast to forms of “imprissonment” (ongoing unwanted situations because we do not really follow our own unique course and discourse).

How Important Are Asteroids in a Birth Chart?

Potentially, very important. Like the fixed stars, an asteroid can sometimes become one of the dominant factors in a particular birth chart—especially when it occupies an angular position or forms an exceptionally close aspect to the Sun, Moon, Ascendant, Midheaven, or a planet. We need only realize that Juno leads us toward true partnership and marriage, Eros toward our true passion in every sense, and Orcus-Vanth toward living our own lives instead of remaining puppets trapped in the webs of the outside world, to recognize that asteroids and dwarf planets hold important treasures for the soul. And these are just 3 examples…

There is also an interesting astrological paradox involved. Traditional astrology has long recognized the unusual strength of planets that are stationary. A planet that appears almost motionless in the sky can become exceptionally pronounced in a horoscope. This principle can help us understand why relatively small celestial bodies should not automatically be dismissed as insignificant.

A birth chart is, by definition, a fixed representation of a particular moment. An asteroid that may move relatively quickly through the zodiac becomes “frozen” into that natal configuration. Its position can therefore function almost like a static director within the chart: a highly specific point through which a particular theme is organized and expressed throughout life. There is something almost Taoist about this principle—the unmoving point that nevertheless sets other things in motion.

This does not, however, mean that every asteroid in a birth chart is equally important. With thousands of named asteroids available, indiscriminate interpretation quickly produces meaningless noise. The astrologer’s task is to identify the asteroids that are genuinely activated in the individual chart.

One of the most common mistakes in asteroid astrology is therefore applying the same orb rules to asteroids that we use for the major planets. Asteroid interpretation generally requires much tighter orbs. A close conjunction or aspect can be strikingly specific; a loose one may mean very little. This distinction is essential if asteroid astrology is to remain a precise interpretive technique rather than becoming a system in which virtually anything can be “found” in every horoscope.

See the section on asteroid orbs below for practical guidelines.

How Do I Interpret Asteroids?

Interpreting asteroids is fundamentally an art of nuance and contextualization. An asteroid should not be treated as a miniature planet with a fixed list of keywords. Its meaning emerges through its relationship with the rest of the horoscope.

Whitehead’s concept of prehension provides a useful philosophical analogy. In Whitehead’s process philosophy, an entity does not exist in complete isolation; it becomes what it is partly through the way it takes account of, or “prehends,” other elements of reality. Asteroids can be approached in much the same way astrologically. The meaning of Eros, Juno, Psyche, Pallas, or any other asteroid is not contained in the asteroid alone. It emerges from the network of relationships in which that asteroid participates.

An Eros conjunct Venus, for example, is not simply “Eros plus Venus.” The two symbols qualify one another. Eros conjunct Saturn will express the Eros principle very differently, as will Eros conjunct Uranus, Neptune, the Ascendant, or the Midheaven. House placement adds another layer by showing where the theme is most likely to manifest, while the sign describes something about how it seeks expression.

There is also a useful symbolic analogy with the Heisenberg principle, although this should not be confused with a claim about quantum physics itself. More than two million asteroids are currently known. I have personally analyzed, tested, and described roughly a thousand of them, but no practicing astrologer can meaningfully add a thousand asteroids to every birth chart. Even several dozen may already be close to the practical limit.

Asteroid astrology therefore always begins with selection.

The astrologer has to compose a workable bouquet from an enormous field of possible objects. Some asteroids and minor planets I consider fundamental enough to include in almost every serious chart analysis. Among these are Ceres, Juno, Eros, Eris, Orcus, Nessus, Chiron, 1998 BU48, and Makemake. Others should be selected according to the initial inspection of the natal chart, the questions being asked, and the particular problems or themes brought forward by the client.

This is where the Heisenberg analogy becomes useful. What we choose to include partly determines what we are able to observe. A chart containing twenty carefully selected asteroids does not reveal exactly the same symbolic landscape as the same chart containing a different set of twenty. The underlying birth chart has not changed, but the resolution through which we examine it has.

In that sense, the asteroid selection functions almost like an observational instrument. A microscope does not create the cellular structures it reveals, but changing magnification changes what becomes available to perception. Likewise, selecting relationship asteroids will bring one layer of the horoscope into sharper focus, while choosing objects associated with trauma, creativity, sexuality, vocation, ancestry, or spirituality will illuminate other layers.

This does not mean that the astrologer is free to manufacture whatever interpretation is desired. The selected asteroid still has to demonstrate its relevance through position, close aspects, angularity, repetition, and integration with the established structure of the natal chart. Selection opens a field of observation; the chart itself must then confirm whether a particular asteroid is significant.

For this reason, I do not recommend indiscriminately loading hundreds or thousands of asteroids into a horoscope. The result is not greater precision but informational overload. The real skill lies in creating the right asteroid bouquet for the individual chart: a stable core of essential asteroids combined with a carefully chosen second layer based on the horoscope and the client’s actual questions.

Once that selection has been made, interpretation can proceed through a practical hierarchy:

  1. Start with a core asteroid set. Use a limited number of asteroids and minor planets that have repeatedly demonstrated broad interpretive value.
  2. Inspect the traditional chart first. Identify its dominant planets, houses, aspects, tensions, and recurring themes before expanding the chart.
  3. Select additional asteroids deliberately. Choose them according to the natal structure and the specific questions, experiences, or problems that require greater resolution.
  4. Check the orb. With asteroids, close aspects matter disproportionately. Wide planetary-style orbs quickly generate noise.
  5. Check what the asteroid aspects. Contacts with the Sun, Moon, Ascendant, Midheaven, chart ruler, or otherwise dominant planets deserve particular attention.
  6. Check the house and sign. The house shows where the asteroid theme operates, while the sign helps describe how it expresses itself.
  7. Look for repetition and confirmation. An asteroid becomes especially convincing when it sharpens a theme already visible elsewhere in the chart.
  8. Do not confuse quantity with accuracy. More asteroids do not automatically produce a better reading. The goal is not to see everything, but to select the objects that allow the relevant structure to become visible.
  9. Do check the chart in serennu.com. This site offers accurate positions of many asteroids. The ones with very narrow aspectations (within ½ degree) are important. For Eris, some Centaurs and Plutinos 1 degree is acceptable.

The art of asteroid astrology therefore lies partly in interpretation, but just as importantly in curation. With millions of possible objects available, the astrologer’s first task is not to interpret them all, but to decide which celestial bodies deserve a place in the chart being studied.

Asteroid Orbs: How Exact Should an Aspect Be?

Twenty years of testing have revealed a remarkably consistent pattern:

  1. For transits, an orb of 30 arcminutes (½ degree) before or after an exact conjunction, opposition, square, or trine is the norm.
  2. In a natal chart, an orb of 30 arcminutes (½ degree) before or after an exact conjunction, opposition, square, sextile, trine, or other aspect is generally appropriate. In asteroid astrology, conjunctions, oppositions, squares, and trines are the most important aspects.
  3. For Plutinos, Eris, and some Centaurs, an orb of one degree can be acceptable in transit. In a natal chart, Plutinos may remain influential within an orb of one and a half to two degrees.
  4. The strongest effects of transiting asteroids, Centaurs, Plutinos, SDOs, Cubewanos, and even Sednoids are generally observed from the moment the object enters an orb of ½ degree, through the exact aspect (0°00′), until it moves beyond ½ degree on the separating side of the aspect.

In practice, the ½-degree rule is one of the most effective ways to separate meaningful asteroid contacts from the enormous amount of background noise produced when thousands of minor bodies are added to a chart.

The meaning of Vesta in Astrology

Vesta (minor-planet designation: 4 Vesta) is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometres (326 mi). It was discovered by the German astronomer Heinrich Wilhelm Matthias Olbers on 29 March 1807, and is named after Vesta, the virgin goddess of home and hearth from Roman mythology.

 

Mythology and Asteroid Interpretation

Fortuna |

Goddess Fortuna

Asteroids discovered in the nineteenth and early twentieth centuries were often named after figures from Greek and Roman mythology. Then follows something of a gap. In the twenty-first century, as large numbers of TNOs (Trans-Neptunian Objects) were discovered, mythological names from other cultures increasingly came into use and continue to be used today.

When considering asteroid names in general, one enters partly into the field of Kabbalarian (not Kabbalistic) sound effects and what might be called the “egregorical cloud.” When a name—especially a mythological name—has been used for many centuries in association with a very specific image, narrative, and set of attributes, a kind of egregoric entity may come into existence. Its imagined reality may then become attached to, and catalyzed by, an asteroid or dwarf planet that has been given that name. This phenomenon can often be observed quite clearly in the case of the Jupiter Trojans and the previously mentioned group of asteroids discovered in the nineteenth century.

However—and this is very important—one cannot rely on mythology alone to determine an object’s astrological effect. The most important factor is usually the discovery chart of the asteroid or dwarf planet. A synthesis of these two factors—the discovery chart and the mythological or egregoric field associated with the name—provides a much more reliable indication of the object’s possible meaning in a chart.

The third phase is empirical testing. Repeated observation across many charts should gradually reduce the remaining uncertainty and refine the interpretation until a relatively stable consensus emerges, useful and reliable enough for the object to be integrated into astrological practice.

An example of this process is the Plutino Lempo. Lempo is an unusual multiple Trans-Neptunian system whose components orbit their common barycenter. Astrologically, Lempo appears prominently in the charts of people with a pronounced talent for metaphysical insight. Yet this characteristic was identified through chart observation independently of the mythological figure after whom the object was named. The Finnish mythological associations of Lempo do not provide an obvious explanation for this observed astrological characteristic.

This illustrates an important methodological problem. A mythological name may sometimes illuminate the astrological meaning of a newly discovered object, but in other cases it may actually obscure or distort it. The mythology should therefore never be allowed to dictate the interpretation before the object’s discovery chart and its behavior across a sufficiently large number of natal and transit charts have been examined.

Common Myths and False Claims About Asteroids

A surprising number of misconceptions about asteroid astrology are based not on observation, but on assumptions about what an astronomical object should or should not be capable of doing. Size, distance, classification, and historical convention are frequently treated as though they automatically determine astrological relevance. Yet these assumptions become remarkably inconsistent when examined more closely.

Myth 1: Asteroids Are Too Small to Have an Astrological Effect

Probably the most common objection is that asteroids are simply too small to matter. According to this argument, the major planets can have astrological significance because they possess enormous mass, while a relatively small asteroid cannot possibly establish a meaningful relationship with a person, event, or birth chart.

The problem is that astrology has never demonstrated that astrological significance is proportional to physical mass. If mass were the determining factor, the entire hierarchy of astrological factors would have to be reorganized accordingly. Pluto, for example, would immediately present difficulties, while many objects presently ignored by mainstream astrology would deserve considerably more attention. The inconsistency becomes even clearer within asteroid astrology itself:

Many astrologers readily accept Ceres, Pallas, Juno, Vesta, and Chiron, yet dismiss other minor planets because they are supposedly “too small.” There is no obvious astronomical logic behind this distinction.

Ceres has a diameter of approximately 940 kilometers, while Pallas and Vesta are considerably smaller. Juno is only around 230 kilometers across. Chiron is smaller still, with an estimated diameter of roughly 200 kilometers. Yet the Solar System contains numerous bodies of comparable or substantially greater size. Beyond Neptune we find objects such as Eris, Haumea, Makemake, Orcus, Quaoar, Gonggong, and Sedna, several of which dwarf the traditionally accepted asteroids in physical dimensions.

Eris provides perhaps the most obvious example. It is a dwarf planet almost as large as Pluto and substantially more massive, yet there are still astrologers who accept Chiron without hesitation while questioning whether Eris could have any astrological relevance. Whatever one’s position on astrology itself may be, this distinction cannot reasonably be defended on the basis of astronomical size.

Myth 2: Trans-Neptunian Objects Are Too Far Away to Matter

A related argument concerns distance. Asteroids or Trans-Neptunian Objects are sometimes dismissed because they are supposedly too distant from Earth to participate meaningfully in an astrological relationship.

Again, the argument becomes problematic the moment it is applied consistently. Pluto has been part of modern Western astrology for almost a century despite orbiting at an enormous distance from Earth. Astrologers who accept Pluto therefore already accept the principle that great astronomical distance does not automatically exclude astrological significance.

The same problem becomes still more apparent with objects such as Eris and Sedna. If an astrologer claims that distance itself determines whether an object can participate in a chart, a precise boundary would have to be established: at what distance does astrological relevance suddenly cease? Forty astronomical units? Fifty? One hundred? Five hundred? And on what empirical or metaphysical principle would such a boundary be based?

There is no established astrological law that provides such a cutoff.

From the perspective I use, the more relevant concept is not conventional physical causation but prehension: the Whiteheadian idea that entities participate in networks of relation and experience rather than existing as absolutely isolated units. Within such a framework, the question is not simply, “Is this object large enough or close enough to exert a force upon us?” The more interesting question is whether a meaningful relationship can exist between the astronomical object, the configuration of the chart, and the event or organism represented by that chart.

Astrology has always operated much more naturally within such a relational model than within a crude model of mechanical force.

Myth 3: Only the Traditional Asteroids Have Been Proven to Work

Another persistent misconception is that Ceres, Pallas, Juno, Vesta, and sometimes Chiron constitute a special class of astrologically legitimate minor bodies, while everything beyond them is speculative.

Historically, however, this selection is largely the result of discovery chronology and astrological habit. Ceres was discovered in 1801, Pallas in 1802, Juno in 1804, and Vesta in 1807. They entered astronomical and eventually astrological literature early enough to acquire a privileged position. Chiron, discovered in 1977, subsequently became enormously popular among astrologers and was gradually incorporated into modern astrological practice.

Their popularity does not demonstrate that the Solar System conveniently contains five or six astrologically meaningful minor bodies surrounded by millions of meaningless ones.

It demonstrates that these were among the objects astrologers happened to investigate first.

The discovery of the enormous population beyond Neptune makes the old distinction increasingly difficult to defend. We now know that the Solar System contains a vast architecture of Centaurs, Plutinos, Cubewanos, scattered-disc objects, detached objects, and other populations that were unknown to the astrologers who established much of twentieth-century asteroid practice.

The appropriate response is therefore not to assume that all these objects are astrologically significant—but neither is it reasonable to assume in advance that they are insignificant.

They have to be tested.

Myth 4: If an Asteroid Has Meaning, Its Mythological Name Must Explain It

This is another assumption that can easily distort research. Because so many asteroids and minor planets carry mythological names, astrologers sometimes begin with the mythology and subsequently search charts for confirmation.

This reverses the proper order of investigation.

As discussed above, mythology can certainly contribute to an object’s symbolic field, particularly when a name has accumulated centuries or millennia of cultural associations. But the mythology should not be allowed to dictate what an asteroid must mean.

The discovery chart, astronomical characteristics, repeated chart observation, and eventually accumulated empirical experience should be considered alongside the mythology. Sometimes these different layers reinforce one another remarkably well. Sometimes they do not.

Lempo is a good example of why this distinction matters. Its observed association with unusual metaphysical insight is not self-evidently derived from the Finnish mythological figure whose name it carries. Had interpretation begun exclusively with mythology, an important characteristic of the object might easily have been overlooked.

Myth 5: With Millions of Asteroids, You Can Make a Chart Say Anything

This objection contains more truth than the previous ones—but only when asteroid astrology is practiced badly.

With approximately two million known minor planets, it is indeed possible to search retrospectively for names or symbols that appear to correspond with almost any person, event, profession, illness, relationship, or psychological characteristic. If thousands of objects are thrown into a chart after the event, coincidence and confirmation bias become inevitable.

That is precisely why serious asteroid astrology requires methodological restrictions.

The solution is not to reject asteroids, but to work with a deliberately selected bouquet of objects, tight orbs, clearly defined aspects, discovery charts, repeated observations, and objects chosen because they are relevant to the particular chart or research question. In practical consultation work, there is rarely any reason to place hundreds, let alone thousands, of asteroids into a single chart.

Asteroid astrology becomes meaningful not by adding everything, but by learning what to select, why to select it, and how precisely to test it.

The central mistake behind many criticisms of asteroid astrology is therefore the same: an assumption is substituted for observation. An object is declared too small, too distant, too obscure, too recently discovered, or insufficiently traditional before anyone has seriously investigated what it actually does in charts.

A more productive principle is much simpler:

Do not assume that an astronomical object works because mythology says it should. But do not assume that it cannot work because astronomical convention, size, or distance says it should not. Test it.

Asteroid Classes in Astrology

Not all asteroids and minor planets belong to the same astronomical population. Their orbits range from objects that repeatedly enter the immediate neighborhood of Earth to distant bodies that require thousands of years to complete a single revolution around the Sun. Some occupy remarkably stable orbital zones; others cross planetary orbits, move between the giant planets, exist in resonance with Neptune, or travel along extremely eccentric paths into the remote Solar System.

These distinctions may also be astrologically significant. An asteroid’s mythology and discovery chart remain important, but its astronomical family provides another layer of information. Orbital behavior describes the actual physical relationship of an object to the architecture of the Solar System. It is therefore reasonable to investigate whether different orbital populations also tend to express different kinds of astrological behavior.

The following classifications should not be understood as rigid astrological doctrines. They are better regarded as working categories within which recurring patterns can be tested.

ATEN ASTEROIDS

Aten asteroids are near-Earth asteroids whose semimajor axes are smaller than Earth’s, although their orbits generally extend outward far enough to cross Earth’s orbit. Their orbital periods are therefore usually shorter than one year.

Astrologically, Atens can be approached as an extremely immediate class of objects. They belong to the terrestrial neighborhood and repeatedly intersect the orbital territory occupied by Earth. If astronomical proximity and orbital interaction have symbolic counterparts, Atens should be investigated for themes involving immediacy, intrusion, rapid manifestation, confrontation, and events entering directly into personal experience.

They are especially interesting for transit research because some move rapidly through the zodiac. Their speed also means that their natal positions can be highly individualizing.

SAMPLE: The Meaning of Aten-Asteroid Aphophis in astrologie

APOLLO ASTEROIDS

The Apollo asteroids are another major population of near-Earth objects. Unlike the Atens, their semimajor axes are larger than Earth’s, but their eccentric orbits cross Earth’s orbit.

Their repeated passage through Earth’s orbital domain makes them particularly interesting astrologically. Symbolically, the crossing itself may be significant: something originating outside the ordinary terrestrial orbit enters our immediate sphere.

Apollo objects may therefore deserve special attention in research involving intersections, encounters, disruptions, opportunities, external forces entering personal circumstances, and sudden activation. Their significance, however, should ultimately be established object by object rather than inferred solely from membership in the Apollo class.

HUNGARIA ASTEROIDS

The Hungaria asteroids occupy a relatively compact region inside the main asteroid belt, generally between Mars and the main concentration of Main-Belt objects. They tend to have relatively high orbital inclinations and form a dynamically distinctive population.

Astrologically, the Hungarias are intriguing because they inhabit something resembling a border territory. They are neither ordinary near-Earth objects nor typical inhabitants of the Main Belt. Their orbital isolation and relatively inclined trajectories suggest a useful research hypothesis involving independence, specialization, separation from the collective, and the maintenance of a distinctive trajectory within a larger system.

Whether individual Hungarias actually display these characteristics must, of course, be determined through chart research.

AMOR ASTEROIDS

Amor asteroids approach Earth’s orbit from outside but, unlike Apollo asteroids, do not presently cross it. Many occupy orbital space between Earth and Mars.

This creates an interesting astronomical distinction. The Apollo crosses the boundary; the Amor approaches it.

Astrologically, this makes the Amor population worth investigating in relation to approach, attraction, proximity, anticipation, and relationships that come close to manifestation without necessarily producing direct intersection.

The name Amor itself is an astronomical class name derived from asteroid 1221 Amor and should not be mistaken for proof that all Amor asteroids concern romantic love.

Aten, Apollo, Hungaria and Amor Asteroids belong to the so called Inner Main Belt Asteroids, which they share with Arjuna and Atira Asteroids.

MAIN-BELT ASTEROIDS

The enormous Main Belt between Mars and Jupiter contains the majority of the traditionally known asteroids, including Ceres, Pallas, Juno, and Vesta.

This is the great reservoir from which classical asteroid astrology developed. Main-Belt asteroids occupy relatively stable Solar System territory between the terrestrial and giant planets. Astrologically, they appear capable of providing extraordinary specificity and differentiation.

Where planets describe large complexes of human experience, individual Main-Belt asteroids can function almost like fine-resolution symbolic markers. They may specify particular talents, behaviors, relationships, psychological mechanisms, professions, persons, circumstances, or recurring motifs that the major planets alone describe only broadly.

This is one reason asteroid astrology should not be regarded merely as a collection of additional “mini-planets.” Its principal value is often an enormous increase in the resolution of the chart.

SAMPLE: The Meaning of Asteroid Seeberg in Astrology

CYBELE ASTEROIDS

The Cybele group occupies the outer region of the Main Belt, beyond most Main-Belt asteroids and inward of the Hilda population. Their orbits are influenced by Jupiter while remaining distinct from the Hildas and Jupiter Trojans.

Astrologically, Cybeles can be investigated as inhabitants of a transitional region between the ordinary asteroid belt and the gravitational domain increasingly dominated by Jupiter.

This makes them potentially interesting in connection with expansion, transition toward larger systems, social integration, amplification, and the movement from personal or specialized concerns toward broader collective structures. Many Cybele asteroids have a strong sexual or sensual meaning in the chart.

SAMPLE: Several Cybele Asteroids with a sexual connotation are summed up is this list among asteroids from other classes

HILDA ASTEROIDS

The Hilda asteroids occupy a 3:2 mean-motion resonance with Jupiter. Their orbital relationship with Jupiter produces a characteristic dynamic structure rather than a simple belt.

This resonance is astrologically important as a concept. A Hilda does not merely happen to be near Jupiter’s orbital territory: its movement is organized through a persistent mathematical relationship with Jupiter.

The Hildas therefore provide an excellent population for studying whether orbital resonance itself produces recognizable astrological characteristics. Possible themes to investigate include synchronization, periodic activation, integration into larger cycles, and the modification or amplification of an asteroid’s individual symbolism through a Jovian framework.

JUPITER TROJANS

The Jupiter Trojans share Jupiter’s orbit around the Sun, clustering primarily around the planet’s L4 and L5 Lagrange regions approximately 60 degrees ahead of and behind Jupiter.

They constitute one of the most fascinating asteroid populations for astrology because their identities are embedded within Jupiter’s orbital architecture.

Traditionally, Jupiter Trojans have largely been named after figures associated with the Trojan War, creating an unusually dense mythological field involving warfare, alliances, loyalty, rivalry, strategy, heroism, betrayal, fate, victory, and defeat. But the core drama of many Jupiter Trojans lies in a need to harmonize excessive yang-energy (expansive martial / masculine energy)

Here astronomical structure and an accumulated mythological or egregorical cloud overlap to an unusual degree. This makes the Jupiter Trojans particularly valuable for studying the interaction between orbital family, individual discovery chart, and collectively reinforced mythology.

Cybele Asteroids, Hilda Asteroids, the Thule Group (only 3 discovered objects) belong to the Outer Main Belt Asteroids. Jupiter Trojans are even orbiting in the orbit of Jupiter.

PLUTINOS

Plutinos are Trans-Neptunian Objects occupying the 2:3 resonance with Neptune—the same resonance occupied by Pluto. They complete two solar orbits for every three completed by Neptune.

Astrologically, Plutinos deserve considerably more attention than they usually receive. They occupy a genuinely different dynamical domain from Main-Belt asteroids and participate in the same fundamental resonance that structures Pluto’s orbit.

Their long periods mean that their sign positions are generational, but this does not make them astrologically insignificant. Houses, angularity and especially exact aspects can individualize them strongly.

Research suggests that Plutinos can operate as deep structural factors, sometimes associated with processes that develop beneath ordinary conscious awareness and emerge with considerable intensity when activated. Their effects should not simply be described as “Plutonian,” however. Each Plutino requires independent investigation.

CUBEWANOS

Cubewanos, or classical Kuiper Belt objects, take their informal name from 1992 QB1. Unlike Plutinos, they are not primarily defined by a strong Neptune resonance. They occupy comparatively stable orbits in the classical Kuiper Belt.

This distinction may be astrologically important. Where resonant objects are dynamically tied to a planetary rhythm, Cubewanos possess a greater degree of orbital independence.

They can therefore be investigated for themes involving autonomy, persistent underlying structures, independent development, and slow processes that do not require direct planetary mediation.

Among the important objects associated with the classical Kuiper Belt are bodies large enough to demonstrate why dismissing minor planets on the basis of size is untenable.

SAMPLE: Several meanings discussed of Cubewanos in Astrology
SAMPLE: The Meaning of Albion / 1992 QB1 in Astrology

HAUMEANS

The Haumean family is especially interesting because it is not merely an orbital category. It is a collisional family associated with the dwarf planet Haumea. Its members possess related orbital characteristics and distinctive surface compositions, indicating a shared physical history.

Astrologically, this gives the Haumeans a rare property: they constitute something resembling an actual astronomical family genealogy.

They consequently provide an exceptional laboratory for investigating whether objects produced by the same ancient physical event retain some common astrological signature. Themes of fragmentation, common origin, differentiation, inheritance, rupture, and the persistence of identity after separation are obvious hypotheses—but they should be tested rather than imposed.

OTHER NEPTUNE RESONANTS

Not every resonant Trans-Neptunian Object is a Plutino. Numerous objects occupy other mean-motion resonances with Neptune, including 1:2, 2:5, 3:5, 4:7 and other relationships.

These populations may prove particularly important for a future astrology that takes orbital dynamics seriously.

A resonance is literally a sustained numerical relationship between orbital cycles. Astrologically, such objects invite investigation of synchronization, recurrence, entrainment, periodicity, and structured relationships between otherwise separate systems.

Different resonances may eventually prove to possess different astrological characteristics. This remains a field in which considerably more systematic research is needed.

CENTAURS

centaurs in astrology

Centaurs are minor planets whose orbits generally lie among and cross the territories of the giant planets. Chiron is the best-known example, but it is only one member of a much larger population.

Centaurs are dynamically unstable on astronomical timescales. Their paths can be altered substantially through encounters with the giant planets, and many are understood as objects transitioning inward from more distant reservoirs.

Their astronomical behavior provides an unusually powerful symbolic model: crossing boundaries, moving between planetary domains, instability, transition, mediation, disruption, and transfer between different levels of the Solar System.

Astrologically, it is therefore questionable to reduce the entire Centaur population to Chiron’s familiar “wounded healer” formula. Nessus, Pholus, Chariklo and other Centaurs demonstrate why each object deserves independent interpretation.

The Centaur may be an astrological category in its own right, but individual Centaurs need not mean the same thing.

DAMOCLOIDS AND RETROGRADE OBJECTS

Damocloids are unusual small bodies with comet-like orbits but little or no visible cometary activity. Many possess very eccentric and highly inclined orbits, and some move retrograde around the Sun.

These objects are dynamically unlike ordinary Main-Belt asteroids.

Astrologically, Damocloids and other strongly inclined or retrograde bodies deserve particular attention because their trajectories run dramatically against the dominant geometry of the planetary system. A retrograde object literally revolves around the Sun in the direction opposite to most major planets.

This suggests research into themes such as countercurrents, reversal, outsider processes, inversion, return, resistance to collective direction, and phenomena that enter an established system from an unusual orientation.

Their often comet-like orbital histories may add another dimension: something arriving from the outer reaches of the Solar System, briefly entering the planetary domain and eventually withdrawing again.

SCATTERED-DISC AND DETACHED OBJECTS

The Scattered Disc contains distant objects whose eccentric and often inclined orbits reflect strong gravitational interactions, particularly with Neptune. Their perihelia may approach Neptune’s region while their aphelia extend enormously farther outward.

Detached objects, by contrast, possess perihelia sufficiently distant that Neptune cannot easily explain their present orbital architecture through ordinary close encounters. They therefore appear, in an important sense, dynamically detached from the familiar planetary system.

Astrologically, these two populations should probably not be treated as identical.

Scattered-Disc Objects suggest displacement, scattering, extreme oscillation between proximity and remoteness, and the consequences of powerful encounters. Detached objects suggest something different: separation, autonomy, remoteness, inaccessible structures, and processes operating beyond ordinary planetary integration.

Eris is among the most important bodies associated with this distant region and alone demonstrates that such objects cannot reasonably be dismissed as insignificant simply because they are remote.

SAMPLE: The meaning of Typhon in Astrology

SEDNOIDS

The Sednoids occupy one of the most remote known populations of the Solar System. Sedna is their prototype. These bodies possess extremely distant perihelia and enormous, highly elongated orbits that carry them far beyond Neptune.

Sedna requires roughly eleven thousand years to orbit the Sun. Human civilization as we know it occupies only a portion of a single Sedna cycle.

This produces an entirely different astrological scale.

A Main-Belt asteroid may provide extraordinary individual specificity. A near-Earth asteroid may produce rapidly changing configurations. A Sednoid, by contrast, barely moves through the zodiac during an individual human lifetime.

Its astrological significance must therefore be sought primarily through house placement, angularity, extremely close natal aspects, and activation by faster-moving bodies rather than ordinary sign interpretation.

Conceptually, Sednoids may represent the deepest temporal layer presently available to asteroid and dwarf-planet astrology: extreme duration, remoteness, primordial structures, collective memory, and processes whose timescale enormously exceeds individual human existence.

Their importance may consequently lie precisely in what initially appears to make them astrologically irrelevant—their extraordinary distance and slowness.

Orbital Class as an Additional Layer of Astrological Meaning

These populations suggest that asteroid astrology should eventually move beyond interpreting isolated objects solely through their names. At least four distinct layers can be investigated:

  1. The individual object and its discovery chart
  2. Its name, mythology, history, and possible egregorical field
  3. Its astronomical properties and orbital family
  4. Repeated empirical observation in natal charts, progressions, and transits

The fourth remains decisive. Orbital classification should generate hypotheses, not predetermined meanings.

Yet it would be equally premature to assume that the extraordinary architecture of the Solar System has no astrological significance. An Aten crossing Earth’s orbit, a Hilda locked into resonance with Jupiter, a Centaur migrating between the giant planets, a Plutino synchronized with Neptune, and a Sednoid spending millennia in the remote Solar System are astronomically very different phenomena.

If astrology is fundamentally concerned with relationships rather than physical force alone, these differences provide a rich and largely unexplored field of research.

The Solar System is not simply a collection of large planets surrounded by insignificant debris. It is an immense relational structure composed of families, resonances, crossings, stable zones, unstable populations, collisional remnants, captured objects, and bodies moving along trajectories that reach into regions only recently discovered.

Asteroid astrology has barely begun to explore what this architecture may mean.

The Popular Major Asteroids and Their Meaning in Astrology

 

Vesta, Eros and Ceres

 

CERES — motherly love; depression; empty-nest syndrome; nourishment; providing supplies; preparations; preparing for scarcity; saving; bodily care; fertilization; passing through the gateway to the underworld

Ceres was discovered on January 1, 1801, by Giuseppe Piazzi. Ceres measures approximately 965.2 by 961.2 km. Today, Ceres is no longer classified as an asteroid but as a dwarf planet. It was named after the Roman goddess of agriculture—particularly grain—and motherly love (Demeter in Greek mythology), the mother of Proserpina (Persephone).  See also our main page about the meaning of Ceres in Astrology.

JUNO — the committed partner; marriage; finances; ability to appeal to the masses; the state treasury

Juno measures approximately 290 × 240 × 190 km and was the third Main-Belt asteroid to be discovered, after Ceres (now classified as a dwarf planet) and Pallas. It was discovered on September 1, 1804, by Karl Ludwig Harding and named after Juno, the supreme Roman goddess and equivalent of the Greek Hera.

Juno is indispensable in the interpretation of the natal chart when it comes to information about the committed life partner. Combined with the information derived from the cusp, ruler, and planetary occupants of the seventh house, Juno provides a remarkably precise indication of the kind of life partner we attract and the underlying rules and dynamics of that partnership.

PALLAS — politics and strategy; organizational talent; altruism and solution-oriented thinking; recognizing and seeing through patterns

Pallas was discovered on March 28, 1802, by Heinrich Wilhelm Olbers and measures approximately 582 × 556 × 500 km. Pallas was the second asteroid to be discovered, after Ceres, and is also the second-largest object in the Main Belt after Ceres. Vesta, however, has a greater mass. Pallas was named after Pallas Athena, the Greek goddess of wisdom and warfare.

The principal characteristics of Pallas are high intelligence, brilliant insights, altruism, solution-oriented and humanitarian thinking, strategic thinking—particularly political strategy—and political engagement in general; the ability to recognize and see through patterns; organizational talent; human values; competitiveness, determination, strong willpower, and achievement orientation; justification of the struggle for a cause; success and expansion through courageous action; and father-daughter relationships. In women, Pallas can stimulate independence and the determination to stand up for one’s own opinions.

4 VESTA — dedication; sense of duty; that from which one must periodically distance oneself; disillusionment; sources of fire; priesthood; the healthcare system; love as torment; widespread recognition as a trendsetter; suppressed or sublimated sexual energy; irrational sexual embarrassment, shame, or guilt

Vesta is the third-largest asteroid and was discovered by Heinrich Wilhelm Olbers on March 29, 1807. Due to its size and exceptional brightness, it is the only asteroid that can occasionally be seen with the naked eye under favorable conditions. Its dimensions are approximately 560 × 578 × 458 km. Vesta was the fourth asteroid to be discovered, after Ceres (1801), Pallas (1802), and Juno (1804).

433 EROS — passion in the broadest sense of the word; sex; eroticism

Eros was discovered in Berlin by Gustav Witt on August 13, 1898. The asteroid has a strange, elongated shape resembling a peanut in its shell and measures approximately 34.4 × 11.2 × 11.2 km.

Eros is primarily associated with passion in the broadest sense of the word. It is a mistake to treat Eros solely as a sexual asteroid. Although sex and eroticism are certainly part of its domain, its sign, house, and aspects provide detailed information about one’s true passions in life in general—what excites us, fascinates us, and makes us feel intensely alive. This makes this very small asteroid extremely important when considering passion, personal fulfillment, and what gives life its fire and intensity.

2060 CHIRON

The personal blind spot; wound in the soul; (over)civilization; the identity crisis of people around the age of 51; shows gaps in one’s individualization process and in what aspects it is underfed; altruism; ingenuity applied for the benefit of others; usually a dislike of violence and love for civilization and cultivation; detached intelligence; wants to heal; when afflicted badly, a clinical, cold cruelty may manifest itself.

On October 18, 1977 Chiron was the first Centaur ever to be discovered of this special class of asteroids. The object was spotted by Charles Kowal. Chiron crosses the orbits of Saturn and Uranus and was estimated to be 166 km in diameter, but in 2011 the Herschel Space Observatory suggested a diameter of 218 km. In contrast to what was believed earlier, Chiron does not contain ice, but interestingly has a weak coma, making Chiron a comet-like object, just like the Centaur Echeclus.

 

The Five-Volume Asteroids in Astrology Series

The results were first published in Dutch in the Asteroïden-Gids in one huge volume, but now 5 volumes have been created and published for the English reading public, with number 6 on the way. These volumes, written by Asteroid Astrology specialist Benjamin Adamah encompass the major asteroid families and are systemized in:

Asteroid Astrology FAQ

 

Is Ceres an Asteroid?

Historically, yes, but astronomically Ceres is now classified as a dwarf planet. It is located in the Main Asteroid Belt between Mars and Jupiter.

Is Pluto an Asteroid?

No. Pluto is a binary-dwarf planet (Pluto-Charon) and a Trans-Neptunian Object. More specifically, it belongs to the resonant population known as the Plutinos, which occupy a 2:3 orbital resonance with Neptune.

Are Plutinos and Plutoids the Same Thing?

No. Plutinos and plutoids are not the same classification, although the terms are frequently confused in astrological literature.

A Plutino is a Trans-Neptunian Object in a 2:3 mean-motion resonance with Neptune: it completes two orbits around the Sun for every three completed by Neptune. Pluto is the best-known member of this dynamical population, hence the name Plutino.

What Is a Plutoid?

A plutoid is a dwarf planet orbiting the Sun beyond Neptune. It must be sufficiently massive for its own gravity to make it approximately spherical, while not having cleared the neighborhood of its orbit. Pluto, Eris, Haumea, and Makemake are classified as plutoids. Ceres is a dwarf planet but not a plutoid because it orbits within the Main Asteroid Belt. Plutoid should not be confused with Plutino: a Plutino is defined by its 2:3 orbital resonance with Neptune, whereas a plutoid is defined by its dwarf-planet status and trans-Neptunian orbit.

Is Chiron an Asteroid?

Chiron was initially classified as an asteroid, but it is now recognized as a Centaur. Centaurs are small Solar System bodies whose unusual orbits generally lie among those of the giant planets.

What Are Trans-Neptunian Objects?

Trans-Neptunian Objects, or TNOs, are minor planets orbiting the Sun beyond Neptune. They include Plutinos, Cubewanos, scattered-disc objects, detached objects, and several other dynamical populations.

What Is a Discovery Chart?

A discovery chart is a horoscope calculated for the time and place at which an astronomical object was discovered. It provides very important clues to the object’s astrological character and should be studied alongside its mythology and subsequent behavior in charts.

Does an Asteroid Always Express the Mythology of Its Name?

No. Sometimes the correspondence is striking; in other cases, the observed astrological effect differs considerably from what the mythology would suggest. The name should therefore never dictate the interpretation in advance.

Why Are So Many Asteroids Named After Mythological Figures?

The first asteroids were predominantly given names from Greek and Roman mythology. More recently, particularly among TNOs, names have increasingly been drawn from mythological traditions throughout the world.

Can Asteroid Names Themselves Become Astrologically Significant?

Possibly. A mythological name that has carried a stable collection of stories, images, and associations for centuries may possess what can be described as an egregorical field. This may interact with the astrological expression of the object, although it should never replace observation and testing.

What Does an Asteroid’s House Placement Mean?

The house indicates the area of life in which the asteroid is most likely to manifest. An asteroid closely connected with an angle or strongly emphasized house can become particularly important.

What Does an Asteroid’s Sign Mean?

The sign describes the manner or style in which an asteroid’s principle tends to operate. With asteroids, however, exact aspects and house placement should generally receive greater weight than sign interpretation alone.

Are Asteroids Important on the Ascendant or Midheaven?

Yes. An asteroid closely conjunct the Ascendant, Midheaven, Descendant, or IC can become exceptionally prominent. Angularity is one of the first things to check when evaluating an unfamiliar asteroid.

Can Asteroids Be Used in Transit Astrology?

Yes. Transit research is one of the best methods for establishing what an asteroid actually does. Exact contacts with the Sun, Moon, angles, chart ruler, and important natal planets can produce particularly clear results.

Can Asteroids Be Used in Progressions?

Yes. Progressed asteroids and contacts between progressed chart factors and natal asteroids can be significant, especially when the aspect is extremely precise and reinforces an already important natal theme.

Can Asteroids Describe Relationships?

Very effectively. Juno, for example, is particularly important for committed partnerships, while Eros can reveal areas of intense passion. Relationship analysis becomes considerably more detailed when carefully selected asteroids are combined with the traditional planetary factors.

Can Asteroids Describe Specific People?

Sometimes with remarkable precision. Name asteroids and other strongly relevant objects can coincide with particular individuals, but they should never be used as isolated proof. Tight aspects and repetition across several chart factors are much more convincing.

Can Asteroids Predict Events?

Asteroid transits can help identify the nature and timing of specific developments, particularly when they activate an important natal configuration. They should normally be interpreted within the context of the entire chart rather than as isolated predictors.

Why Not Put Every Available Asteroid in a Chart?

Because the result becomes statistically and visually meaningless. With millions of objects available, accidental correspondences are inevitable. The skill lies not in using everything but in selecting a meaningful bouquet of asteroids appropriate to the chart and the question being investigated.

How Do I Know Whether a New Asteroid Is Astrologically Important?

Start with its discovery chart, astronomical characteristics, and only then its name and mythology. Test it across a substantial number of natal charts and transits. Look for repeated effects under tight aspects rather than memorable coincidences.

What Is the Biggest Mistake in Asteroid Astrology?

Starting with a desired interpretation and then searching for asteroids that confirm it. Good asteroid research works in the opposite direction: observe first, compare repeatedly, and interpret afterward.

Where Should a Beginner Start?

Begin with a small group of well-tested objects such as Ceres, Pallas, Juno, Vesta, Chiron, Eros, Nessus, Eris, Orcus, and Makemake. Learn how they behave in your own chart and in charts you know well before expanding the selection.

What Is the Main Advantage of Asteroid Astrology?

Resolution. The traditional planets provide the basic architecture of a horoscope. Carefully selected asteroids can reveal finer structures within that architecture, adding details that would otherwise remain invisible.

How Do I Find Asteroids in My Birth Chart?

The easiest way is to use an online ephemeris or chart calculator that allows you to add minor planets manually. I usually use Serennu.com, which is particularly useful for working with large numbers of asteroids, Centaurs, and Trans-Neptunian Objects. Astro.com can also be used to add many additional objects to a natal chart.

What Is an MPC Number and Why Is It Important?

An MPC number is the permanent number assigned to a numbered minor planet by the Minor Planet Center. For serious asteroid work, these numbers are extremely useful because they identify the astronomical object unambiguously.

For example, Juno is (3) Juno, Vesta is (4) Vesta, Eros is (433) Eros, and Nessus is (7066) Nessus. When searching for an asteroid in an astrology program or ephemeris, using its MPC number is often safer and more efficient than searching by name alone.

This becomes increasingly important when working with obscure asteroids. Names may be misspelled, confused with similar names, or displayed differently by different databases, while the MPC number remains tied to the same object.

Where Can I Look Up an Asteroid’s MPC Number?

The Minor Planet Center (MPC) is the primary astronomical authority for minor-planet designations and numbering. Asteroid databases and ephemerides also usually provide the number alongside the object’s name.

A useful working habit is therefore to record an asteroid as number + name, for example:

433 Eros — 7066 Nessus — 15760 Albion

This prevents confusion and makes it much easier to reproduce your research in different astrology programs.

Should I Search by Asteroid Name or Number?

Preferably by MPC number whenever the software allows it. Names are useful for reading and interpretation; numbers are better identifiers.

When building your own asteroid research database, always record the MPC number together with the name. With millions of known minor planets and an ever-growing number of named objects, this simple practice prevents a surprising number of errors.
