There is some real world truth to the relation of Lilith to a dark moon. The Dark Moon refers to a hypothetical satellite of the Earth. It would be a very small physical body (about 3 meters across) and have a great velocity (3 hours and 20 minutes for a complete orbit around the Earth). It would also be in eclipse, thus be invisible. In 1918, the astrologer Walter Gounold named this Dark Moon, or Black Moon, Lilith.
