The Path of Eris &
The Eris Synodic Cycles

2003 - 2016

Harmonic Cycles of Growth
in Consciousness


Eris, recently discovered and larger than Pluto, catalyzing the total re-classification of planets and the resultant formation of the Dwarf Planet class in which Pluto now resides. Mythologically, Eris is the Greek god of strife. Astrologically, Eris can be thought of as the Great Disrupter, but with a purpose, sort of shaking up what is stagnant in consciousness or the status quo so a greater re-organization can eventually follow, one more fitting to our accelerating and expanding evolutionary transition in consciousness. More about Eris.

Presented below are the primary Planetary Synodic Cycles occurring with Eris from 2003 through 2016; and their star alignments in sidereal Pisces, as Eris moves through the belly of Cetus, the psycho-emotional world of collective human consciousness. An exploration of the historical path of Eris, from the 1900's brings insight to its expression now. Jupiter and Eris begin a new synodic cycle in 2011. A rare Venus-Mars-Eris Synodic Synchronization occurs in April 2013. In 2016 Uranus and Eris start a new synodic cycle, the last having started in 1927. The Uranus -Eris synodic cycle is also explored in this article.

Synodic cycles are created when two (or more) planets align in thier orbits around the Sun. The synodic cycle theme, defined by the planets involved and the star alignments at the time, will unfold until the two planets align again, marking the completion of the synodic cycle and the beginning of the next one.

There are many synodic cycles with unique astrological themes occurring simultaneously creating a harmonic symphony of creative unfoldment in consciousness. Synodic cycles can be thought of as longer-term underlying currents, much like the backdrop chorus of a symphony, providing the underlying astrological context guiding our evolution.

See Synodic Cycles & Planetary Retrogrades to learn the basics about synodic cycles.

All dates and ecliptical locations in this article are heliocentric—looking directly from the Sun (not from the Earth), although there is little diference due to the distance of Eris.

Venus-Mars-Eris Synodic Synchronization April 2013
2008 - 2023 Synods

Venus-Mars-Eris Synodic Synchronization

The April 2013 Venus-Mars synod occurs within a 2° orb to the Venus-Eris and Mars-Eris synods. The next Venus-Mars-Eris synodic synchronization occurs in April 2045 with an orb of 3°.

Other Eris Synodic Cycles - 2003 through 2014

The only outer planet creating more than one synod with Eris during this period is Jupiter, which occurs every 12 to 13 years (June 2011 and May 2023). A Uranus-Eris synod occurs on December 10, 2016 (producing the Uranus-Eris generation).1 The other synods are with: Mars (occurring about every 687 days); Earth (occurring every 365-6 days); Venus (occurring about every 225 days); and Mercury (occurring about every 88 days).

Generally there are two Earth-Eris synods for every Mars-Eris synod. Venus synods occur much more often, very close to a Venus Year, which is 224.701 Earth days ( ~0.615 Earth years ), moving slightly faster than Earth. Mercury-Eris synods occur near the rate of Mercur'y year, which is 87.95 Earth days. The synodic periods are very close to the orbital periods of the inner planets because Eris moves only slightly by the time the planet conjoins Eris again.

1. Uranus joins forces with Eris in mid-2016 in oppostion to Haumea, starting an unprecedented and prominent planetary configuration consiting of three geocentric conjunctions. The first occurs with Ceres on June 9, 2016, the second occurring on September 25, and third occurring in March of 2017. Uranus makes its oppositions to Haumea starting on May 10, 2016 (just before the first Uranus-Eris conjunction), continuing through early 2018. Jupiter joins Haumea in oppostion to Uranus and Eris starting on December 26, 2016. Mars conjoins the Uranus-Eris conjunction in oppostion to Jupiter-Haumea on February 26-27, 2017 (on a Solar Eclipse Feb 26 UT).

Excerpt from the March 10, 2013 Lunar Planner

Venus, Mars & Eris

Venus, Mars and Eris create a finale energetic in this lunar cycle before and after the Balsamic Moon. It starts with a new Venus-Mars synodic cycle on April 5. A new Venus-Eris synodic cycle then starts on April 6, hours before the Balsamic Moon. Venus and Mars conjoin just after the Balsamic Moon. Mars and Eris begin their synodic cycle on April 8. Venus and Eris then conjoin on April 8 and Mars and Eris conjoin on April 9-10, just before the New Moon. The star alignments are all the same for each of these events, with exception of the first event, the new Venus-Mars synod, which occurs just slightly before the location of Eris in late sidereal Pisces, less than 2° to Eris. For all practical purposes, they all synthesize energetically.

Eris synods occurring now in late sidereal Pisces conjoin Revati of Pisces; Baten Kaitos of Cetus; and the stars forming the outstretched arms of Andromeda. The Eris-Ravati-Baten Kaitos conjunctions are explored in: Eris, The Great Disrupter, Revati & the Global Economic Crisis. Curiously, this is also the location of the following April 10, 2013 New Moon.


The astrophysical resonances of Venus govern the heart bio-energy centre (chakra), and the thymus, which is the neurological control center for the immune system. Like the thyroid (governed by Mercury) is reflexed to the liver, the thymus is reflexed to the spleen. The heart chakra is our centre of intuitive knowing, harmony, magnetic attraction, that which we value, love, romance, and sexual rapture. It is where we find our capacity for compassion and appreciation of beauty. The heart chakra and thymus resonate to the emotional tone of fear and judgment. It is fear that shuts the heart down and causes all immune related problems. We defend our fear with judgment.

Venus (and the heart chakra), when mature and clear, expresses love in art and beauty, with a wonderful capacity for unconditional acceptance of all conditions--true, non-judgmental love. The unconditionally open heart receives and expresses love that is harmoniously balanced. Mature Venus is open to new experience, is courageous, optimistic, and aware of soul intent and purpose--as the unconditionally open heart is where soul fully radiates its light. Mature Venus is also sociable, fashionable, artistic, good willed, benevolent, diplomatic, and magnetically sensuous. Venus is also of wealth and resources and plays a prominent role in financial matters and the flow of money.


Mars is an expressive and initiating creative force. Mars is of sexuality, vitality, life force, and power. In its mature expression, Mars stimulates our capacity to respond in assertive action. It is of leadership, self reliance, and victorious. It is audacious, brave, instinctual, passionate and willful. For the less mature, or when poorly placed in a chart, Mars can express as the awry or ballistic use of power, lack of self-control, abuse in all if its forms, and with selfish motive and greed that is based in the fear of not surviving or not being provided for. The Mars aspect of self (sacrum, base chakra, adrenals sexual organs) is the area generally held in most judgment by many people—due to this force having been used destructively and manipulatively in the history of the solar system resulting in aberrations and devastation of life; hence often dubbed the planet of war. Because of this, total rejection and lack of love is often projected toward the Mars quality / base chakra of self—alienating it even more.

Synopsis (from the March 11, 2013 Lunar Planner)
This synod in sidereal Pisces conjoining Revati definitely emphasizes financial issues in relationships from an emotional-based perspective. Venus is exalted in sidereal Pisces, in fact, at this location conjoining Revati (a part of revealing why Venus effects the cycles of economics and money). As such, Venus expresses dynamically and independently with confidence. Fiery Mars in this aquatic area of the zodiak is somewhat subdued and passive, thus more prone to go with the flow of Venus’ lead, which will be more outgoing. This, as one might surmise in our times, is not a bad thing. In general, a Venus-Mars synthesis (conjunction) inspires action from the heart. Both, however, synthesize with Eris. This may create somewhat of a disruption or discord between the masculine and feminine, or between the creative and receptive, or simply living true to heart verses taking contrary action simply to survive. Any such issues surfacing, whether in self or in partnerships, ultimately serve for a more appropriate reorganization or rebalancing of the Venus-Mars / feminine-masculine relationship in the longer term. Another way this may manifest is by stimulating the expression of a feminine warrior quality that would challenge, confront or overturn any awry masculine expression. Another potential manifestation of this energetic is something beneficent emerging due to some past discordant condition or experience.

This rare synthesis (both the conjunctions and synods occurring over these several days in April 2013) may indicate some type of a catalytic turning point that allows a re-tuning that may help to equilibrate the feminine-masculine energetic in the longer term. Observing female-male relationships during this time can bring insight into the nature of this synthesis, and observing the nature of any issues surfacing can bring insight into what needs re-tuning in the longer term. This event also nests between the Jupiter-Eris synod (June 2011) and the Uranus-Eris synod (2016), both of which should have more dramatic influences, may also stimulate a longer term transition regarding the related stellar and planetary themes.

This synthesis, and the planets and stars involved, are presented in more detail in the March 11, 2013 Lunar Planner. An introduction to the 2016 Uranus-Eris synod is presented below.

The Emergence of Eris - from the 1900's

The Path of Eris in Cetus

In the early 1900's Eris was in the very southern heavens, deep in the subconscious realm of consciousness. Eris was emerging from the constellation Sculptor (latter sidereal Aquarius), and then would move upward under the tail and through the bowels of Cetus later in the century.

In a sense, we can consider that Eris was amassing the essence of the stars and constellations though which she was traveling, gathering momentum to emerge into humanity's awareness with the energetics it had taken on along its journey.

While in Sculptor, Eris was embodying the Sculptor's essence—as if planning to play a role in re-sculpting our lives; and deep below the humanitarian Waterman, Aquarius—embodying her purpose to aid humanity to re-orient itself toward a humanitarian based society.

Traveling deep below the trashing tail of Cetus in the mid-1900's, and still hidden from humanity, Eris was silently observing, from the depths, the nature of the psycho-emotional turbulence of the surface waters in which humanity flounders. Then entering the very bowels of Cetus, Eris begins to amass the very inner and dark workings of the fear-based technobureaucratic monster of collective human consciousness. Observing Eris' past path, we might surmise she has shown up with some profound wisdom to apply in her mission as she dramatically emerges into our conscious reality.

Curiously, Eris emerges into our awareness as she conjoins Revati of Pisces, when this distant body was discovered, and Baten Kaitos of Cetus, where she would start to make her presence and potent role as the Great Disrupter known, and where she would begin to actively apply all the momentum and wisdom she had gained prior to her emergence.

Now, at the turn on the century, and of the millennium, Eris begins her work by disrupting the status quo in this very specific area of human consciousness, revealed by Revati and Baten Kaitos—specifically regarding issues surrounding the financial aspects of life and how resources of the world are entwined in the belly of human consciousness, which create the paradox of freedom and slavery, the rich and poor, and the struggle in which people are endlessly battling to emerge successfully from this paradoxical monster.

Current Eris Star Alignments

Eris resides at ~25° sidereal Pisces and conjoines Revati of Pisces in 2003-2004. Eris lies within a ±1° orb to Revati from 1999 through 2007; and it lies within a ±2° orb to Revati from 1994 (near the time of its discovery) through 2012.

In 2012, when Eris is 2° past Revati, it conjoins Baten Kaitos of Cetus. Eris lies within a ±1° orb to Baten Kaitos from 2007 through 2015. Eris lies within a ±2° orb to Baten Kaitos from 2004 through 2020.

Due to the very long-period (slow orbit) of Eris around the Sun (~560 Earth years), Eris moves very little through the zodiac during this time. Thus there are many Earth-Eris synodic cycles progressing slowly and working with the Revati / Baten Kaitos theme.

Revati, Zeta Pisces, literally is riches, money, financial resources, wealth of the human world. Revati is found in the essence of the psychic and emotional world of human affairs—in the belly of ole' Cetus, as revealed by the close ecliptical longitudes of these two stars.

Although conjoining Revati, which is nearly on the ecliptic plane, Eris is still south of the ecliptic in the Aquatics, actively working in the inner workings of Cetus, the fear-based technobureaucratic monster of collective human consciousness, the whale of human emotional experience. Eris is thus working at a very deep emotional gut level, having a profound effect in redefining humanity's relationship with financial resources and the path of the heart—perhaps helping us to get our priorities in proper order by shifting our emotional drive from pursuing the quantity we have in life to the quality and harmony all people have in life. And, in Eris style, perhaps turning our insides out in the process.

More about the current role of Eris, Revati and Baten Kaitos can be found in the new article of October 2008:
Eris, The Great Disrupter, Revati & the Global Economic Crisis.

Synodic Astrology: Eris & Uranus - 1927 - 2016

A new Uranus-Eris synodic cycle begins in Dec of 2016. The last Uranus-Eris synod occurred around 1927 in early sidereal Pisces on the Vernal Point. The vernal point is the primary fiducial (marking point) for the "moving axis" in the cycle of "Earth's Precessional Cross"; the timepiece that governs the "Evolutionary Cycle of the Soul Collective on Earth." Due to Earth's precession, in 1927, the Vernal Point was then aligned with Diphda, the thrashing tail of Cetus the Sea Monster, at about 7° sidereal Pisces (of course it has now moved to 5° sidereal Pisces creating the erect Precessional Cross). Diphda's theme is that of getting knocked down and thrashed around in the psycho-emotional world of collective human consciousness.

You can learn more about the Earth's ~25-000 year Precesional
Cycle & the Precessional Cross on Earth's Precessional Cycle and Sidereal Astrology web pages.

Although Eris was not yet discovered, this 1927 Uranus-Eris synod should have catalyzed the beginning of a significant and radical transition for humanity, yet one working at a very sub-conscious level since Eris was not yet discovered. This Uranus-Eris-Diphda synod suggests the any year cycle would be catalyzing a radical and unexpected change in the nature of how humanity gets thrashed around in the tormenting and turbulent emotional waters created by the fear-based technobureaucratic monster. Of course we would not become aware of this nor would it manifest until the discovery of Eris in 1995, when Eris became active for humanity at a conscious level. The theme of this cycle continues through the next Uranus-Eris synod of Dec 2016.

The correlation of global events and historical transitions surrounding the 1927 Uranus-Eris synod may be ideal for astrologers to explore in order to gain more insight into the astrological nature of Eris.

A few events occurring during this time were: In Global Communications - The first transatlantic commercial telephone service was established between New York and London. There were breakthroughs in radio and television, with television's first successful long-distance broadcast. These were technological shifts severing the limits of the past (a Uranian theme), ones that would then continue throughout the synodic cycle. The new technological developments also disrupted humanity's world perception regarding possibilities in time and space, fitting to Eris' nature, just as Eris' discovery disrupted humanity's world view, ultimately to embrace additional planets in Pluto's realm and the resultant need to redefine our astronomical classification of planets (forming the Dwarf Planet category).

These were also the days of Ford's Model A; Mae West, Duke Ellington, and Ernest Hemingway. However, shortly to follow was the Great US Stock Market Crash in 1929, which led to the Great Depression (fitting to the Vernal-Point-Diphda theme). Although originating in the US, the Depression spread to Europe and all other parts of the world causing severe political disarray. This also proved opportunistic for tyrants like Hitler and Stalin. World War II followed a decade later.

Remember, Uranus and Eris move quite slowly so their active orb lasts over a long period, and a synod merely marks the start of cycle which will then unfold over time—the Uranus-Eris cycle being about 89 years.

The 1927 Uranus-Eris synod occurred prior to the erect 270° Precessional Cross, thus adding to elicit our "inner need to initiate change" in our Precessional Cross portal of evolutionary change. The 2016 Uranus-Eris synod, although not in principal aspect to the Precessional Cross, occurs after the precessional transition marked by the cross, in the beginning of "initiate change" in our ~25,000-year Great World Cycle, and of course much later in sidereal Pisces with entirely different star alignments. Uranus-Eris align almost a degree past Baten Kaitos of Cetus, as Eris starts its emergence from the Piscian aquatics. Mars comes along to activate the December 2016 Uranus-Eris synod in Jan 2017.

Will we see another dramatic technological turning in 2016 catalyzed by Uranus-Eris, and another shift in the psycho-emotional world of human collective consciousness—perhaps one of emergence as Eris moves more north from the belly of ole' Cetus and through the last degrees of sidereal Pisces.
