Pluto: Difference between revisions

Pluto was discovered in 1930, then thought to be the ninth and final planet of the Solar System. Its first moon, Charon, was discovered in 1978. In 2005, 2 more smaller moons were discovered. In 2006, arguments began to arise on whether Pluto was actually large enough to be considered a planet. After much debate, Pluto (along with the asteroid Ceres and the object Eris) became newly classified as dwarf planets.

In 2007, a space probe named ''New Horizons'' was launched to gather more information on Pluto. It was scheduled to arrive at the dwarf planet in 2014 or 2015. It was also the first spacecraft to ever visit Pluto.
