Pluto - The Planets

pluto

Pluto is the ninth planet in the solar system. Discovered in 1930 and immediately classified as a planet, its status as such is currently in dispute. Pluto has an eccentric orbit that is highly inclined with respect to the other planets and takes it inside the orbit of Neptune. Its largest moon is Charon, discovered in 1978; two smaller moons were discovered in 2005. Pluto's astronomical symbol is a P-L monogram. This represents both the first two letters of the name Pluto and the initials of Percival Lowell, the man who lent his name to the observatory that was used to find Pluto. An alternate symbol resembles that of Neptune, but has a circle in place of the middle spoke in the top center. The New Horizons probe, which blasted off on January 19, 2006, is expected to reach Pluto in July 2015 and send back information about it.
