Planets in Astrology - Hypothetical Planets

Hypothetical Planets

Some astrologers have hypothesized about the existence of unseen or undiscovered planets. In 1918, astrologer Sepharial proposed the existence of Earth's "Dark Moon" Lilith, and since then, some astrologers have been using it in their charts; though the same name is also (and now, more commonly) used in astrology to refer to the axis of the actual Moon's orbit. The 20th-century German school of astrology known as Uranian astrology also claimed that many undiscovered planets existed beyond the orbit of Neptune, giving them names such as Cupido, Hades, Zeus, Kronos, Apollon, Admetos, Vulcanus, and Poseidon, and charting their supposed orbits. These orbits have not coincided, however, with more recent discoveries by astronomers of objects beyond Neptune.

Other astrologers have focused on the theory that in time, all twelve signs of the zodiac will each have their own ruler, so that another two planets have yet to be discovered; namely the "true" rulers of Taurus and Virgo. The names of the planets mentioned in this regard by some are Vulcan (ruler of Virgo) and Apollo, the Roman god of the Sun (ruler of Taurus). Another version of this theory states that the modern planets discovered so far correspond to the elements known to the ancients—air (Uranus, god of the heavens), water (Neptune, god of the sea), and fire (Pluto, god of the underworld)—which leaves the elements earth and ether (the fifth element of the fiery upper air). In other words, it is claimed that the two planets to be discovered will be named after an earth god or goddess (such as the Horae), and after Aether, the Roman and Greek god of the upper air and stars.
