The moons of Pluto are moons which orbit the dwarf planet Pluto. There are five moons orbiting the dwarf planet in total. The first one discovered was Charon which is near one quarter the size of Pluto. Charon was also sometimes considered a double dwarf planet. The second was Nix, the third was Hydra, the fourth moon was Kerberos, and the fifth moon to be discovered was Styx.
