Pluto was discovered in: 1930, by Clyde Tombaugh. In 2006, specifications were introduced for the word "planet," containing three main conditions a body must meet to be considered a planet. Pluto did not meet one of these conditions and was therefore downgraded from a planet to a "dwarf planet" or a "minor planet" in astronomy. Astrology continues to classify Pluto as an important and influential planet.
In Greek mythology, Pluto was the God of the Underworld. Pluto and Uranus are the only planets named after Greek gods, while the rest of the planets' names come from Roman gods.
