More Info
Although Pluto was classified scientifically as a Dwarf Planet in 2006, astrologically it is still classified and used as a regular planet. Discovered in 1930 by Clyde Tombaugh, Pluto is the 9th planet from the Sun, beyond Neptune. Astrologically, it is regarded by most modern astrologers as the planetary ruler of Scorpio (Mars being the traditional ruler).
Pluto symbolizes power, lust, sex or sexual violence, obsession, tenacity, concentration, death, rebirth, transformation, secrets, destruction and rot.
