Disturbances in the orbit of Neptune set astronomers on the hunt for another undiscovered planet. The search took 25 years, during which the principal investigator, Percival Lowell, passed away. His research was continued by Clyde Tombaugh, who officially discovered Pluto in 1930.
Pluto’s 248-year orbit is more elliptical than the planets previously discovered; he spends 14 to 30 years in each sign. Since he was discovered less than 100 years ago, we’ve yet to experience in living memory Pluto in all the signs.
As such, the jury is still out on what Pluto may be astrologically speaking. Some astrologers call him the “most important planet in the sky.” Others swear he has little impact at all.
The Meaning of Pluto in Astrology
Pluto is most commonly associated with our most primordial creative and destructive forces. Where he sits may give insight into how we transform, transmute, regenerate, heal, renew or purge.
Pluto’s also been linked to the hidden, the occult, the taboo, or even the shameful.
Power is another term associated with Pluto. Both empowerment as a positive term, as well as the more sinister urges toward repression, domination, manipulation, and obsession.
