Pluto has five known moons. The largest, Charon , is half the size of Pluto. Charon’s period of revolution is exactly equal to the rotation period of Pluto itself; in other words, Charon is in synchronous orbit around Pluto.
Pluto has five known moons: Charon, Nix, Hydra, Kerberos, and Styx. This moon system might have formed by a collision between Pluto and another similar-sized body early in the history of the solar system.
