Before we explore these new bodies, let's put things in perspective, by talking about distances.
  • The Earth is 1 Astronomical Unit (AU) from the Sun. 1 AU is equal to about 150 million km.
  • Neptune is about 29.76 AU from the Sun at perihelion, 30.3 AU at aphelion.
  • Pluto is about 29.73 AU from the Sun at perihelion, 49.5 AU at aphelion.
  • Beyond Neptune is the Kuiper Belt, which covers the distance between 30 to 50 AU from the Sun
  • Beyond the Kuiper Belt is hypothesized the Oort Cloud, about 50,000 to 100,000 AU from the Sun
  • The nearest star to our own, Proximi Centauri, is 260,000 AU away


A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

Currently, there are only five bodies considered Dwarf Planets: Ceres, Pluto, Eris, Makemake and Haumea. Some others may be added later. Salacia is most likely a Dwarf Planet so I am including it as one, but she was initially classified a Cubenwano. I will not be talking about Ceres here, as her orbit is primarily between Mars and Jupiter. And of course, I won't be discussing Pluto, as this page is for Trans-Plutonian bodies. But for those interested, here is a NASA page on all of the Dwarf Planets

Pluto, Eris, Makemake and Haumea have also been placed in a special sub-category called "Plutoids", and so far, they are the only ones. (What is a Plutoid? "Plutoids are celestial bodies in orbit around the Sun at a semimajor axis greater than that of Neptune that have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium (near-spherical) shape, and that have not cleared the neighbourhood around their orbit. Satellites of plutoids are not plutoids themselves, even if they are massive enough that their shape is dictated by self-gravity." That's from an IAU Press Release Jun 11, 2008.)

There are five symbols shown for Eris. The one on the left was designed by Zane B Stein as a possible glyph for the this body. The middle two have been used by the Discordians to represent the Hand of Eris, long before this body was discovered. Next was submitted by Bogdan Krusiński, who says it is the symbol being used for Eris by astrologers in Poland. And on the far right is the one that is used for Eris in
Time Passages software.

2003 UB313 had been officially declared the 10th Planet by the IAU, until August 24, 2006. On this date, they voted on an official definition of the word "Planet", and this body was reclassified. It is now one of the three members of a new classification, "Dwarf Planet", along with Pluto, and Ceres. But though they may be 'Dwarf' in size, they are anything but dwarf in significance. It was given an official number, 136199. And, it now has a name!
From the Smithsonian Astrophysical Observatory came an official announcement, September 13, 2006, Circular #8747:
"Following near-unanimous acceptance by both the Committee on Small-Body Nomenclature and the Working Group on Planetary-System Nomenclature (in consultation with the discovery team), the IAU Executive Committee has now approved the names Eris for (136199) and Dysnomia for its satellite (136199) Eris I [formerly S/2005 (2003 UB313)" More on this in a moment.


On January 5, 2005, the team of Michael Brown, Chad Trujillo, and David Rabinowitz (David, you may remember, discovered Pholus), discovered a very unique body while looking over photographic plates that had been taken Oct 21, 2003. (It's not unusual for photographic plates to sit for months or even years before they are really studied, since so many of them are taken on a daily basis.) Anyway, when they first recognized what they had found, they decided to research it thoroughly before making a a public announcement, which they finally did on July 29, 2005, (the same day as two other large Kuiper Belt objects, 2003 EL61 and 2005 FY9, were also announced.)


This body had been nicknamed 'Xena', as in the television's most famous female warrior, and her moon had been nicknamed 'Gabrielle' after Xena's constant companion.


But now we need to start calling this body by it's official name of Eris (Greek Ἒρις), the Greek mythological goddess personifying strife. Her Latin name is Discordia. And her moon has been officially named 'Dysnomia', a child of the goddess Eris, who often was used to symbolize lawlessness

Mike Brown gives this account on the naming:

"We officially suggested the name on 6 September 2006, and it was accepted and announced on 13 September 2006.

"The satellite of Eris has received the offical name Dysnomia, who in Greek mythology is Eris' daughter and the demon spirit of lawlessness. As Dysnomia is a bit of a mouthful, we tend to simply call the satellite Dy, for short.

"As promised for the past year, the name Xena (and satellite Gabrielle) were simply placeholders while awaiting the IAU's decision on how an official name was to be proposed. As that process dragged on, however, many people got to know Xena and Gabrielle as the real names of these objects and are sad to see them change. We admit to some sadness ourselves.We used the names for almost two years now and are having a hard time swtiching. But for those who miss Xena, look for the obvious nod* in the new name of the moon of Eris."

*And of course, by "obvious nod", Michael was referring to the fact that the moon was named after a spirit of lawlessness, and the television character Xena was played by actress Lucy Lawless.

Mike Brown has a page about Eris with a lot of interesting information. Check out his Eris page.


Brown describes it as the most distant object ever found to be orbiting the Sun. At 9.7 billion miles, Eris is three times farther from the Sun than Pluto, which averages 3.6 billion miles from the Sun. The newly-discovered object is more distant than the mysterious planetoid Sedna discovered in 2003. But that's only right now. Because of its highly elliptical orbit (with an eccentricity of 0.44177), in 280 years, the planet will be as close as the planet Neptune is to Earth.

Not only is its orbit highly elliptical, but it is tilted 44.187 degrees relative to the plane of the solar system. Pluto's orbit is only inclined 17 degrees.

How big is it? The latest size estimate, as of February 2006, is a diameter of 3000 km. To put that in perspective, our Moon is 3500 km, Pluto is 2300 km, and Pluto's moon Charon only 1200 km.

It takes 557 years for the newly-discovered body to orbit the Sun. Right now, it is on the far side of the Solar System, not too far from its farthest point from the Sun.

On September 10, 2005, astronomers discovered that Eris has a moon, and this was provisionally designated S/2005 (2003 UB313). Some mouthful to say! So, since they nicknamed the main body Xena, they decided to nickname its companion Gabrielle (after the TV warrior's constant companion.)

Here is an excellent website for (mostly) astronomical information and updates on 136199: ERIS


Eris comes from Greek mythology, and the name translates as Strife. But it seems there were two different goddesses by that name. Hesiod wrote, in "Works and Days":

"So, after all, there was not one kind of Strife alone, but all over the earth there are two. As for the one, a man would praise her when he came to understand her; but the other is blameworthy: and they are wholly different in nature.

For one fosters evil war and battle, being cruel: her no man loves; but perforce, through the will of the deathless gods, men pay harsh Strife her honour due.

But the other is the elder daughter of dark Night (Nyx), and the son of Cronus who sits above and dwells in the aether, set her in the roots of the earth: and she is far kinder to men. She stirs up even the shiftless to toil; for a man grows eager to work when he considers his neighbour, a rich man who hastens to plough and plant and put his house in good order; and neighbour vies with his neighbour as he hurries after wealth. This Strife is wholesome for men. And potter is angry with potter, and craftsman with craftsman, and beggar is jealous of beggar, and minstrel of minstrel."

The goddess Hesiod describes who 'fosters evil war and battle' is described as being the sister of Ares (Mars, to the Romans), with Zeus (Jupiter) and Hera (Ceres) as her parents.

Eris, as daughter of Nyx, has some quite interesting siblings, although the list varies depending upon the author.

Hesiod wrote: "And Nyx (Night) bare hateful Moros (Doom) and black Ker (Violent Death) and Thanatos (Death), and she bare Hypnos (Sleep) and the tribe of Oneiroi (Dreams). And again the goddess murky Nyx, though she lay with none, bare Momos (Blame) and painful Oizys (Misery), and the Hesperides ... Also she bare the Moirai (Fates) and the ruthless avenging Keres (Death-Fates) ... Also deadly Nyx bare Nemesis (Envy) to afflict mortal men, and after her, Apate (Deceit) and Philotes (Friendship) and hateful Geras (Old Age) and hard-hearted Eris (Strife)."

Hyginus wrote: "From Nox (Night) and Erebus: Fatum (Fate), Senectus (Old Age), Mors (Death), Letum (Dissolution), Continentia (Moderation), Somnus (Sleep), Somnia (Dreams), Amor (Love) - that is Lysimeles, Epiphron (Prudence), Porphyrion, Epaphus, Discordia (Discord) [Eris], Miseria (Misery), Petulantia (Wantonness), Nemesis (Envy), Euphrosyne (Good Cheer), Amicitia (Friendship), Misericordia (Compassion), Styx (Hatred); the three Parcae (Fates), namely Clotho, Lachesis and Atropos; the Hesperides."

And Eris herself has been listed of the mother of several other interesting beings, called the Kakodaimones, who were the evil spirits which plagued mankind. The moon of the body Eris has been named after the one listed in bold in the following paragraph from Hesiod:

"But abhorred Eris (Strife) bare painful Ponos (Toil), and Lethe (Forgetfulness), and Limos (Starvation), and the Algea (Pains), full of weeping, the Hysminai (Fightings) and the Makhai (Battles), the Phonoi (Murders) and the Androktasiai (Man-slaughters), the Neikea (Quarrels), the Pseudo-Logoi (Lies), the Amphilogiai (Disputes), and Dysnomia (Lawlessness) and Ate (Ruin), who share one another's natures, and Horkos (Oath) who does more damage than any other to earthly men, when anyone, of his knowledge, swears to a false oath."

There are many stories of Eris in literature, but probably the most famous took place at the marriage of Peleus to Thetis. Eris was not invited to the wedding. (Would you invite Strife to your wedding?) When she found out that she had been snubbed, but Hera (Juno), Athena (Pallas), and Aphrodite (Venus) had been sent invitations (by Chiron, in fact), but she had not been invited, she was enraged, and sought revenge. She decided to go to the wedding anyway. Colluthus wrote:

"And now she bethought her of the golden apples of the Hesperides. Thence Eris took the fruit that should be the harbinger of war, even the apple, and devised the scheme of signal woes. Whirling her arm she hurled into the banquet the primal seed of turmoil and disturbed the choir of goddesses. Hera, glorying to be the spouse and to share the bed of Zeus, rose up amazed, and would fain have seized it. And Kypris [Aphrodite], as being more excellent than all, desired to have the apple, for that it is the treasure of the Erotes (Loves). But Hera would not give it up and Athena would not yield."

Zeus saw the quarrel heating up, and called to Hermes (Mercury) to give escort the goddesses to a shepherd named Paris, and instruct him to give the apple to the goddess he saw as the most beautiful. In this way, he sought to resolve the argument. (Some say that Zeus knew what would happen, and planned the whole thing.)

When Paris was told of his honor by Hermes, each of the goddesses tried to sway his decision by offering him a gift. (Bribing the judge?) Hera said if she were chosen fairest of all women, she would make him king of all men; Athena promised him victory in war; and Aphrodite promised him Helene in marriage.

Paris chose Aphrodite, for Helene was one of the most beautiful, desirable of all women. With Aphrodite's aid Paris seduced queen Helene and abducted her to Troy, and this led to the Trojan War.

There are many, many stories of Eris accompanying her brother Ares onto the battlefield. She is often described as having an insatiable desire for bloodshed. Even after all the other gods had withdrawn from battle, she remained, rejoicing over the slaughter.

But she was also mentioned as responsible for other 'battles.' On more than one occasion, for example, she is listed as the cause of marital strife.

Aesop retold one of the Eris stories which may indeed show us one aspect of Eris' meaning to us:

"Herakles was making his way through a narrow pass. He saw something that looked like an apple lying on the ground and he tried to smash it with his club. After having been struck by the club, the thing swelled up to twice its size. Herakles struck it again with his club, even harder than before, and the thing then expanded to such a size that it blocked Herakles's way. Herakles let go of his club and stood there, amazed. Athena saw him and said, 'O Herakles, don't be so surprised! This thing that has brought about your confusion is Aporia (Contentiousness) and Eris (Strife). If you just leave it alone, it stays small; but if you decide to fight it, then it swells from its small size and grows large."

And yet, with all of this, there is another side to Eris. As Hesiod wrote:

"One [Eris] is Trouble and Fighting. But the other is only Healthy Competition."

The ancient astrologers associated war, as well as healthy competition, with the 7th house, and the 7th sign (Libra). Could Eris, therefore, be associated with Libra?


Today, there is a religion that worships the goddess Eris. Well, sort of. Anyway, the members of this faith call themselves Discordians. (Two of the symbols they have used to represent the Hand of Eris are shown at the top of this page as possible symbols for the planet Eris.)

What is the Discordian view of Eris? For that, I'd like to quote from their 'bible', the Principia Discordia:

"...It was not until they traced the Greek writing on the apple that they discovered the ancient Goddess known to the Greeks as Eris and to the Romans as Discordia. This was on the fifth night, and when they slept that night each had a vivid dream of a splendid woman whose eyes were as soft as feather and as deep as eternity itself, and whose body was the spectacular dance of atoms and universes. Pyrotechnics of pure energy formed her flowing hair, and rainbows manifested and dissolved as she spoke in a warm and gentle voice:
"I have come to tell you that you are free. Many ages ago, My consciousness left man, that he might develop himself. I return to find this development approaching completion, but hindered by fear and by misunderstanding.
"You have built for yourselves psychic suits of armor, and clad in them, your vision is restricted, your movements are clumsy and painful, your skin is bruised, and your spirit is broiled in the sun.
"I am chaos. I am the substance from which your artists and scientists build rhythms. I am the spirit with which your children and clowns laugh in happy anarchy. I am chaos. I am alive, and I tell you that you are free.""


KEYWORDS: If you would like to experiment with some preliminary keywords for Eris, please jump to my Preliminary Keywords page, but keep in mind that it is still early in research, and the keyword list may be modified or expanded upon.

It was at its furthest point from the Sun (aphelion) on March 16, 1977, at 13 Aries 36. (1977 was an interesting year. Six days earlier, rings were discovered around the planet Uranus, shaking up our reality, letting us know Saturn wasn't the only ringed planet. And later in the year, November 1, Chiron was discovered, right between Saturn and Uranus.)

Going back in time, it was closest to the Sun (perihelion) on July 7, 1699, at 8 Libra 53. A planet's perihelion is, in many ways, the beginning of its orbital cycle. What shift took place int he world at the end of the 17th Century, as we entered into the 18th Century? Why have some called the 1700's "The Age of Reason and Change"? Could this be related to the perihelion in Libra, sign of the scales of balance, fairness, law and justice?

Obviously, it is way too soon to list meanings for this planet, but it is not too soon to begin studying it astrologically. Here are a few significant positions for Eris:
Discovery position: 19 Aries 45 R
Position when announced to the world: 21 Aries 05 R

Recently, I had occasion to read something that showed me a very positive side to Eris. Astrologer John Halloran posted the following (reprinted with his permission) on alt.astrology.moderated:

Eris - Discord and the Dialectic Process

It appears that the philosopher Hegel saw the evolutionary stage that is beyond Pluto.

Hegel saw the dialectic between thesis and antithesis as a constructive process that leads to a higher synthesis.

There is a discussion of Hegel's ideas excerpted at:

Quotes from this page:

"Dialectic is defined by Hegel as the power (or energy or force) of negativity."

"Dialectic is thus the transition of things, and of knowledge, from potentiality or abstraction to actuality and content, but in such a way that the arising of a fuller determination points beyond itself to a further determination. Every determination is both a result and a new beginning, concrete and abstract, for it occurs within a process of the becoming of a thing (or of knowledge), and hence is concrete relative to the origin of the process but abstract relative to the telos of the whole process. A thing becomes more and more fully developed through this successive dialectic of self-reconstruction."

So discord is part of a constant on-going dialectic process of maturation, of leaving behind one-sided viewpoints and partial truths. It shakes up the status quo and says that a more complete perspective is necessary.

The dialectic is a branch of logic in the art of reasoning and\or disputing. Through the use of it Socrates would lead his adversary to make clear his position on the subject, then, often with the introduction of an absolutely contrary theory, the discussion would end with an admission, on the other side, of an inaccuracy. It was employed to set one theory in opposition with another, and thus to develop a subject in a comprehensive manner. First an idea (a Thesis) was thrown up against another theory (an Antithesis); from this, it was thought, one would advance to a third stage, and the truth would emerge. Often, - though not necessarily - there would come about a combination of both the ideas (a synthesis). From this process, it is thought, one would arrive at the truth of a proposition; this is not to be confused with a negotiation process whereby, usually, a compromise is wrought out.

Henry Alphern wrote (in An Outline History of Philosophy):

"We must analyze everything into what it now is, then analysis will show that it contains its opposite, which in turn will have to be harmonized into something that includes them both. But the resultant synthesis will itself be subject again to a negative element, this then, will be resolved into a still more comprehensive synthesis, which will be subjected once more to the principle of contradiction. The final solution, the ultimate harmony, the last synthesis, the step when it will no longer be necessary to go higher, will constitute the Absolute. The Universe as a whole harmonizes all contradictions, it is the perfect whole, it is the synthesis which we are seeking as our final solution. It, therefore, constitutes the true, the rational, the goal of the dialectic method. The conclusion is that only the whole of reality is rational, because that furnishes a complete view of all things; it is the Absolute, the World, Reason, God."

Hesiod wrote that there were two different Eris goddesses. One of them, the daugher of Nyx (Night) stirred up healthy competiton. Think about the last good, stirring debate you watched. A discussion involving opposing viewpoints, first one side, then the other, at times perhaps getting quite heated. Didn't you come away mentally stimulated, perhaps with your own thoughts galvanized?

Competition comes from the Latin word competere, which means: to strive together, to coincide. The very basis of healthy competition is not to create enmity, but to strive together to come up with something better than existed previously. In a healthy competition, everyone benefits, no matter whoo wins.

President William McKinley was an indefatigable campaigner. He helped rebuild the Republican Party in 1896 by rejecting divisive ethnic issues and promoting pluralism--whereby every group in the nation would prosper and none would be singled out for attack. He once wrote:

"Without competition we would be clinging to the clumsy antiquated processes of farming and manufacture and the methods of business of long ago, and the twentieth would be no further advanced than the eighteenth century."

He was born on January 29, 1843, with Mercury approximately 27 Aquarius 18, closely conjunct Eris at 27 Aquarius 53.

Vice President Hubert H. Humphrey had a mind that quickly grasped complicated issues. He was instrumental in merging two opposing political parties (the Democratic and the Farmer-Labor party), and with their combined backing he was elected Mayor of Minneapolis. He gained a national reputation by his strong stand for civil rights. In fact, in one of the most renowned speeches in American political history, Humphrey told the 1948 Democratic National Convention: "To those who say, my friends, to those who say, that we are rushing this issue of civil rights, I say to them we are 172 years too late! To those who say, this civil rights program is an infringement on states' rights, I say this: the time has arrived in America for the Democratic Party to get out of the shadow of states' rights and walk forthrightly into the bright sunshine of human rights!" Humphrey and his allies succeeded; the pro-civil-rights plank was narrowly adopted. But not without causing strife! As a result of the Convention's vote, the Mississippi and one half of the Alabama delegation walked out of the hall. Many Southern Democrats were so enraged that they formed the "Dixiecrat" party and nominated their own presidential candidate.

He once wrote:

"Freedom is hammered out on the anvil of discussion, dissent, and debate."

Humphrey was born May 27, 1911. This gave him a Mars (25 Pisces 19) conjunct Eris (26 Pisces 39), both square Pluto (26 Gemini 53.)


Because it moves so slowly, this body can take several years to move through one degree. Perhaps that is why some people experience significant events, several years in a row, on a specific date?

  • Research in history should reflect an interesting transition from 1922-1927. Eris was straddling the cusp between Pisces and Aries that whole period:
    • Enters Aries June 3, 1922
    • Retrogrades back into Pisces July 21, 1922
    • Enters Aries April 27, 1923
    • Retrogrades back into Pisces August 28, 1923
    • Enters Aries April 1, 1924
    • Retrogrades back into Pisces September 24, 1924
    • Enters Aries March 9, 1925
    • Retrogrades back into Pisces October 22, 1925
    • Enters Aries February 12, 1926
    • Retrogrades back into Pisces December 5, 1926
    • Enters Aries January 1, 1927 (where it still is to this day)
  • Look especially to 1924 & 1925, when the Spring Equinox occurred only hours away from the Sun/Eris conjunction.
    • 1924: Only a few days after the conjunction in 1924, Greece proclaims itself a Republic. Less than a week after that, Adolf Hitler was sentenced to five years in jail for his participation in the Beer Hall Putsch.
    • 1925: Shortly before the conjunction, a law was passed in Tennessee that, in effect, forbade the teaching of evolution in schools, or "any theory that denies the story of the Divine Creation of man as taught in the Bible." This sparked a major furor, putting on trial a teacher (John T. Scopes) in what was to become one of the most famous trials in history. William Jennings Bryan and Clarence Darrow locked horns in what has become known as the Scopes Monkey Trial.


Here follows the dates and times for the exact conjunction of the Sun with Eris for over a century. We can use this data to study this new body in several different ways:
