In some scientific circles, Pluto is still considered, despite recent controversy, a legitimate planet. You can see it in the image here, the farthest planet out, and very tiny. Yet I find it to be one of the most intriguing of the planetary influences in the Birth Chart.
Jeff Green, founder of Evolutionary Astrology, has built an entire theory, and school, of astrology, around Pluto in the Birth Chart as the key to reincarnational history.
Pluto is not used in Classical and Medieval Astrology in the West, nor in Hindu Astrology in the East, based on the belief that Pluto has never been part of traditional astrology. There is some evidence, however, that the so-called Outer Planets – Pluto, Uranus and Neptune – were indeed known in ancient times, such as in Sumer. Sumerian tablets translated by Zecharia Sitchin tell of a cosmic event within our solar system which – among other great happenings – knocked Pluto from its orbit sending it into its present cold, outermost location.
Other texts describe the remarkable events leading to Uranus’ turning almost onto its side – a state which still mystifies modern physicists; and how Neptune became the “tranquilizer” of our planetary system, somehow holding all the planets within their given orbits.
The key words to Pluto are: Extreme Experiences, Fear, Betrayal, Sexuality, Mysteries and Mystery, Transformation, Power, Death and Regeneration.
