Pluto has 5 moons... I thought it was just Charon
Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Nix, Hydra, Kerberos, and Styx.[22] Pluto and Charon are sometimes described as a binary system because the barycenter of their orbits does not lie within either body.[23] The IAU has yet to formalise a definition for binary dwarf planets, and Charon is officially classified as a moon of Pluto.[24]
