Pluto is a dwarf planet, and the furthest from the Sun in our Solar System. It was a planet until 2006, when it was demoted to a dwarf planet. It has about one-sixth of the mass of Earth's Moon and its moons include Charon, Nix, Hydra, Kerberos, and Styx. One of Pluto's moons, Charon, is larger than it is with a diameter just over half the size.

Planetary statusEdit

There is a lot of controversy on whether or not Pluto is really a planet or not. In August 2006, the IAU declared that Pluto is a "dwarf planet". Others consider it to be a planet. A recent scientific debate on September 26, 2014 states that Pluto should be given back its planetary title, but it is unlikely that it will be given back this title.
