If we use 10 planets in astrology for 12 zodiac signs, how about adding 4 new planetoids (Chiron, Juno, Pallas and Vesta) and 3 dwarf planets (Ceres, Eris and Sedna), and finally another natural satellite of the earth (Lilith)? It would lead to a new arrangement of planetary rulers if the "new" solar system celestial bodies were included. Each sign has a planetary ruler, co-ruler and influence. The newest discovered 10th asteroid/planetoid Hygiea has an unknown role in astrology, nor does the planetesimal Ultima Thule beyond the orbit of Pluto.
