Eris - The Great Disrupter

Eris was discovered on January 5, 2005 by Mike Brown, Chad Trujillo, and David Rabinowitz (Caltech) from images taken on October 21, 2003. Mike Brown reported a discovery time of 11:20 am on January 5, 2005 in Pasadena. The discovery was announced on July 29, 2005. Eris was formally named on Sept 13, 2006. The discovery team gave the planet the provisional name Xena, after the character in the TV series Xena: Warrior Princess played by actress Lucy Lawless. Its previous designation was 2003 UB313.

The eccentric orbit of Eris, with Pluto and Neptune

The orbital inclination of Eris, with Pluto

Eris' Orbital Inclination ~44°
Pluto's Orbital Inclination 17.133°

Eris (pronounced "ee-ris") was discovered in Cetus, the Technobureaucratic Monster of Collective Human Consciousness (~25° sidereal Pisces / 15° south ecliptical latitude). Eris is a bit larger than Pluto. Eris is estimated at 2326 km (±12km) and Pluto is 2320 km. It also shows Methane on its surface as does Pluto. Eris however, has an extreme orbital inclination (44°) as well as a greater eccentric orbit (0.43749), almost twice as long as it is wide. Eris' extreme eccentric orbit swings inside the orbit of Pluto (as well as inside the orbits of the other newly discovered Kuiper Belt Objects) much like Pluto's orbit swings inside Neptune's. Eris is slower moving than Pluto. Eris's year is equivalent to ~558 Earth years, whereas Pluto's is about 248. All of this suggests that Eris may cut through our consciousness in an even sharper, more intense and dramatic way than Pluto, but in a longer process. Eris was responsible for the formation of the new "Dwarf Planet" classification and the reclassification, some say demotion, of Pluto—which caused quite an commotion in both the astronomical and astrological communities—upsetting the apple cart, to use a common phrase. See: Pluto Demoted. Eris's extreme eccentric orbit and its steep orbital inclination is our first clue to Eris' rather radical and intercedeing nature.

Planets with with extreme eccentric orbits tend to bring awareness (or knowledge) from distant realms of consciousness into more conscious realms. Planets with extreme orbital inclinations tend to cut through the comfort of our existing sense of reality.

Eris Mythology & her Moon Dysnomia

Eris is the Greek god of strife. Due to her exclusion from the wedding of Peleus and Thetis, a sea-goddess, spiteful Eris, aroused lust and conflict amongst the goddesses (Hera/power, Athena/wealth, and Aphrodite/love, beauty and rapture) which led to the Trojan war by offering a "golden apple" to the fairest of the three. In short, Zeus proclaimed Paris, the handsome prince of Troy, to act as judge. Paris choose Aphrodite with her promise that Helen, the wife of Menelaus, would become his wife. This ultimately led to the abduction of Helen by Paris and subsequently the 10-year long Trojan war (1194 to 1184 BC.) and its ramifications. (Ref: Iliad & Odyssey)

Also interesting is that at this time (circa 1190 BC), the vernal point (of the moving vernal axis of Earth's Precessional Cross, which reveals where we are in the "evolutionary cycle of the soul," conjoined Menkar, the jaws of Cetus, the techno bureaucratic monster of collective human consciousness. The anti-vernal point conjoined Zubenelgenubi, the southern chelae of the Scorpion, the karmic seat for incarnating souls.

Artist's impression of Eris and Dysnomia

Eris' daughter, Dysnomia, is the name given to the moon of Eris. Dysnomia is said to be the "spirit of lawlessness"—disrupter of civil order. Eris, however, had two daughters, Dysnomia and the opposite and peaceable one, Eunomia, who ends strife, returns order and maintaines social stability.

Eunomia was the goddess of law and legislation and one of the (second generation) Horae along with her sisters Dike and Eirene. The Horae were a trio of beautiful maidens, referred to as The Seasons (spring, summer and autumn), with Eunomia being of Lawfulness, Dike being of Justice, and Eirene being of Peace. They represented all that was good and beautiful in nature manifesting through "natural order in time", like that which grows, blossoms and bears fruit during the three seasons.

Dysnomia is also the name given to a nominal recall (dys) disorder—a memory problem associated with naming (nouns); the inability to retrieve names when needed—"its on the tip of my tongue." It is interesting that finding Eris to be an appropriate name for UB313 also took a long time, curiously fitting to the Dysnomia memory disorder, and its formal naming occurred after witnessing its disrupting effects in the astronomical community. This also elucidates that the disrupting effects Eris creates can linger while we get over the shock from it and that it requires some time for its more positive results, the end of strife, to manifest.

Although the discovery of Eris created disorder at first, a new order followed with the new classification of Dwarf Planets (fitting to the theme of daughter Eunomia). This is significant when considering Eris' astrological character. Eris dismantled limiting conceptual boundaries to open us to a more embrace cosmology. Thus, Eris opens or expands consciousness by upsetting existing, limiting and antiquated structures of consciousness.

Eris’ discovery in Cetus, the Technobureaucratic Monster of Collective Human Consciousness, indicates Eris is disrupting the fear-driven bureaucratic world of mass consensus to help our emergence from the belly of the ole’ whale into a new world paradigm, one based in natural order. Being a very slow mover, Eris is still making its passage through the gut of Cetus—continuing to disrupt fear-based collective human consciousness by revealing the uglies of the technobureaucratic monster driving it. Eris’ influence has been working, for the most part, at sub-conscious emotional level—perhaps continuing to increase the unrest with the status quo in the human populous, but very much serving to awaken the human populous from their acquiescent unconscious slumber in fear

Eris demonstrated, right from the start, her no-nonsense astrological role as the great disruptor. Although discordant Eris creates quite a commotion, it clearly is not without purpose. Eris opens us to see beyond the finite bounds of our current perception, beyond the bounds we place upon ourselves, sort of shaking up what is stagnant in consciousness. In doing so, we are left to redefine and reorganize our world view to embrace a far vaster reality—a view more fitting to our rapidly expanding awareness.

Eris 2000-2020

The Stellar Backdrop

Eris aligns with Revati of Pisces and Baten Kaitos of Cetus, which conjoin in sidereal Pisces.

This chart is a blowup of the red box in the star chart below.

During each of the retrograde loops (shown in the above illustration) a new Earth-Eris (~366-day) synodic cycle begins. The sequential progression of the Earth-Eris cycles create the underlying current of the emerging force of Eris in our lives—in this case, about disrupting the status quo by disclosing what lies hidden in belly of the technobureaucratic monster of collective human consciousness.

The Belly of Cetus

The Path of Eris through Cetus

The Path of Eris through Cetus in Sidereal Pisces

Eris moves up though The Belly of Cetus in 2000-2020 conjoining Baten Kaitos of Cetus, Revati of Pisces, and the bound outstretched arms of Andromeda.

South of the constellation Pisces we find Cetus the sea monster—the Kraken in the story of Andromeda, Perseus, and the Royal Family. Cetus is the fear-instilling technobureaucratic monster of collective human consciousness. Cetus demonstrates a strong emotional turbulence and provides the dramatics of the intense psycho-emotional forces of the human world. The stars of Cetus comprise a principal part of the theme of sidereal Pisces.

In the greater scheme of things, emerging from the depths of watery Pisces, up through the bowels of Cetus, Eris, the Great Disrupter, is serving our greater evolutionary freedom by disrupting the forces driving our fear-based collective consciousness by disclosing clandestine affairs.

South of the whale of human emotional experience is Fornax, the furnace (not shown), which provides the perpetual fire (digestive juices) for our transmutation while participating in the belly of ole' Cetus—in the wet, sensual, and emotional world of human affairs. Alignments with the belly of ole Cetus, marked by the star Baten Kaitos, indicate our need to embrace the emotional aspects of mortal life and to emerge in transmuted form. The value here is to be able to participate from the wisdom of having been there, and to claim the potential rewards, the abundance that life has to offer in all of its forms. Here lies the theme expressed in the story of Jonah and the Whale.

Revati of Pisces

Eris also conjoins Revati, Zeta Pisces, which lies above Baten Kaitos on the ecliptic. Revati literally means riches, money, wealth, and financial resources. Prominent alignments with Revati can indicate material wealth gained from participating in the dramatic psycho-emotional world of human affairs. This zodiacal longitude is a couple of degrees to that of Baten Kaitos, the belly of ole Cetus, where the transformative process occurs while in the whale of human emotional experience. Revati also marks the exalted seat of Venus—bringing attention to our values, financial affairs, the flow of abundance, emotional clarity, and living from the heart. Venus rules money and assets; and Venus dramatically influences economics (especially its retrogrades), as is well known in astrological financial forecasting.


The stars forming the bound outstretched arms of the Princess Andromeda also reside at this ecliptical longitude. In the story of Andromeda and Royal Family, Andromeda was chained to the rocks by the sea to be devoured by Cetus the Sea Monster. This was due to Queen Cassiopeia's boastful and arrogant claim that her daughter was more beautiful than Poseidon's Nereids, the nymphs of the sea. Poseidon responded by sending Cetus to ravage the shores of Ethiopia, which Queen Cassiopeia and King Cepheus ruled. Cepheus was advised to sacrifice Andromeda to Cetus to appease Poseidon. Andromeda, although inheriting this unfortunate sentence, has a far greater and fortuitous destiny awaiting her, as articulated by the beautiful Andromeda Galaxy, which emulates the ideal potential for our Galaxy. Perseus eventually kills Cetus and frees Andromeda. Perseus and Andromeda marry and they go on to create a city and rule a kingdom that bores the Persian world. He and Andromeda bore a family as well. Hercules was descendent of Perseus and Andromeda.

Andromeda is forced to face the sea (her emotions) and Cetus, the sea-monster (the fear-based monster of collective consciousness), which is buried deep beneath the water (in the subconscious mind) only to reveal its menacing head and thrashing tail at the surface shore.

The stars forming Andromeda’s bound outstretched arms articulate not only the bound feminine, but also the bondage of humanity’s prosperous future, which adds to articulate the theme of Baten Kaitos and Revati. This also articulates the subjugation of females and the control of financial resources by the dominant patriarchal-driven bureaucracies.

This zodiacal longitude also brings our attention to financial resources in general and the courage to release fear about not having or surviving, or losing what we do have, both of which drive the tormenting forces of Cetus and the bureaucratic monster of collective human consciousness. Prominent alignments with Revati can also indicate an inherited fortune, or success with wealth and resources in the world.

Buried deep in the subconscious, Upsilon Ceti (conjoining Revati and Baten) supports opportunity for emergence from the belly of ole’ Cetus, that is to emerge from the struggles and fear common to the 3-d bureaucratic realmspace of our current collective consciousness; which in essence produces the mirror image or inversion in consciousness, the revelation of freedom produced from the inside-out, into heartspace. Upsilon Ceti reveals, for those that submerge deep enough within self, well beyond the turbulent psycho-drama of mind, the key to the chains of fear that bind.

Eris Challenges Patriarchal Authority

The discovery and naming of Eris confronts patriarchal authority in a few ways. Provisionally as Xena and then formally as Eris, the female names directly confront our solar system's male dominance, as all major planets have male names, except for Venus. The creation of the Dwarf Planet category also rightfully raised the status of Ceres, mother of the asteroids (a female), as a Dwarf Planet, now at par with Eris and Pluto. Eris also put an end to Pluto delineating the planetary boundary to our solar system, the final masculine planet of death, giving the final word, and hiding what lies beyond. Pluto now is but a gate keeper to more transcendent realms of consciousness. Appropriately Pluto needs an astrological update fitting to modern times, bringing comprehension that Pluto is far more than merely about death and the use of power, but is about making the transition from dominance and control mistaken as power to realizing Pluto is about claiming the power within self, self mastery. Pluto invites us to enter unconscious realms of self to deconstruct neurological patterns we destructively externalize as a false sense of power that impede embodying our true soul-level power. More about Pluto.

In this light, as a powerful warrior female force, Eris especially uncovers and challenges patriarchal dominant miss-deeds and acts of misuse of power, especially regarding male dominance over, or exploitation of, females. Eris takes a stand to reestablish balance to our gender dominance/subservience imbalance by disclosing such discordance.

Eris in Summary

Eris is a feminine warrior archetype that has no fear or hesitation to intercede and expose a greater hidden truth. Eris abhors, will provoke and will challenge the assumption of the reality of a situation when based on false pretense. Eris provokes change by upsetting the status quo, by upsetting the apple cart. Eris discloses and exposes clandestine affairs, or simply what lies hidden behind innocent but naive assumptions about reality. She opens our eyes to what is covered by lies, often revealing something deceitful, shameful, ugly, or simply what is unacceptable behavior, often driven from greed or inflated pride. Although Eris can create a disrupting commotion, upsetting our existing, limiting and antiquated structures of consciousness, she opens us to see beyond the finite bounds of our current perception, beyond the bounds we place upon ourselves by arousing and challenging our egoic defenses. In doing so, we are left to redefine and reorganize our world view to embrace a far vaster reality—a view more fitting to our rapidly expanding awareness. The discord and disruption Eris creates often results in a positive outcome in the longer term, as such how disrupting events can catalyze significant shifts in our lives that we would not otherwise initiate on our own, or by impelling us to take new paths that we would not otherwise embark upon that lead to more appropriate outcomes.
