Pluto has five known moons. Their names, in order of distance from Pluto, are Charon, Styx, Nix, Kerberos, and Hydra
- Charon is the largest moon, about half the size of Pluto itself, and is tidally locked with Pluto, meaning the same side of Charon always faces Pluto
- The other four moons (Styx, Nix, Kerberos, and Hydra) are much smaller, irregularly shaped, and are not tidally locked to Pluto
- These moons likely formed from a collision between Pluto and another similar-sized body early in the solar system's history
In summary, Pluto has a total of five moons, with Charon being the largest and closest, and four smaller moons orbiting farther out
