To most modern Western astrologers, Pluto () is the ruling planet of Scorpio and is exalted in Virgo. In Roman mythology, Pluto is the god of the underworld and of wealth. The alchemy symbol was given to Pluto on its discovery, three centuries after Alchemy practices had all but disappeared. The alchemy symbol can therefore be read as spirit over mind, transcending matter. The symbols were chosen given the close association with Mars which has a similar symbol.
Pluto takes 247 years to make a full circuit of the zodiac, but its progress is highly variable: it spends between 15 and 26 years in each sign.
Astrologically, Pluto is called "the great renewer", and is considered to represent the part of a person that destroys in order to renew, through bringing buried, but intense needs and drives to the surface, and expressing them, even at the expense of the existing order. A commonly used keyword for Pluto is "transformation". It is associated with power and personal mastery, and the need to cooperate and share with another, if each is not to be destroyed. Pluto governs big business and wealth, mining, surgery and detective work, and any enterprise that involves digging under the surface to bring the truth to light. Pluto is also associated with the day Tuesday alongside Mars.
Pluto is also associated with extreme power and corruption; the discovery of Pluto in 1930 coincided with the rise of fascism and Stalinism in Europe, leading to World War II. It also coincided with the Great Depression and the major proliferation of organized crime in the United States.

Its entry in Cancer in 1913, the sign in which it was later discovered, coincided with World War I. It is also associated with nuclear armament, which had its genesis in the research of the 1930s and 40s. Later on, it gave rise to the polarized nuclear stand off of the Cold War, with the mass consumer societies of the United States and other democracies facing the totalitarian state of the USSR. The discovery of Pluto also occurred just after the birth of modern psychoanalysis, when Freud and Jung began to explore the depths of the unconscious.
In real life events and culture, Pluto has been a major astrological aspect. In art, movements like Cubism and Surrealism began to de-construct the "normal" view of the world. In medicine, Pluto is seen to be associated with regenerative forces in the body involving cell formation and the reproductive system. Pluto is considered by modern astrologers to be co-ruler of the eighth house. Many traditional astrologers do not use Pluto as a ruling planet, but do use the planet for interpretation and predictive work, obliquely making reference to projections of influences from higher- to lower-dimensional spaces.
