Lilith in astrology incorporates three entities. We have Black Moon Lilith, Asteroid Lilith and the lesser known Dark Moon Lilith. Together they work as a Triple Moon Goddess, which describes a process of transformation. The three Lilith’s are also useful in pinpointing which brand of Lilith energy is strongest in your chart and at which stage you may have the most issues with. After studying Eris in detail it is apparent to me that she is the higher octave of Lilith. Eris is the Uber-Dark Goddess and by combining her with the outer planets we can see how each corresponds quite neatly with three phases of the moon.
To see the Lilith astrology archetype in terms as a triple goddess makes total sense to me. After I wrote this post I discovered Demetria George had come up with a similar concept about Lilith. Comparing it to the bible story she says: ” The Asteroid Lilith describes the first stage in the mythical journey where she is suppressed, humiliated and flees in a fiery rage to the desolate wilderness. The Dark Moon Lilith depicts the pain of her exile where she plots and executes revenge. The Black Moon Lilith shows how she transmutes her distorted image back into its natural healthy expression”

ORBIT. She is the only solid representation of Lilith found in the main asteroid belt between Mars and Jupiter. Takes 4 years to orbit the Sun. Discovered in 1927. Diameter of 67km.
KEY WORDS. Rebellion, feminist, prostitution, exile, freedom fighter, confrontational, equality, impulsive, innovative, unconventional, asexual, instinctual, hands-on healing.
She is hands on with her energy as represented by the hand like glyph. Earthy and practical, she reflects the part of the creation myth where she protests to God about having the “lay beneath” Adam and not being treated as his equal.
Asteroid Lilith is like URANUS/ERIS. Uranus having been castrated makes him asexual, he is often sited as being the “gay” planet which is suggestive of alternative lifestyles. The fact that he was castrated by Cronus (Saturn) is interesting. Another symbol of patriarchy whipping off power from this eccentric, ball breaker!
