"Centaurs" are a tiny group of seven unusual bodies, neither comets nor asteroids, but possessing qualities of both. The first centaur, Chiron was discovered in 1977, the second, Pholus, in 1992 and the third, Nessus, in 1993. The centaurs have a primarily elliptical orbit in the outer solar system, and most likely originated from the Kuiper belt. They have long orbital periods from 49 (Chiron) to 123 (Nessus) years.
Some astrologers believe the centaurs to be highly significant in an astrological chart.
The study of asteroids in astrology is contoversial, but many astrologers believe that the asteroids do indeed have a part to play in the assessment of an astrological chart. The asteroids are important in archetypal astrology, and include Ceres (the Great Mother), Pallas Athena (Goddess of Wisdom), Vesta (the Temple Priestess) and Juno (Goddess of Marriage) amongst many others.
