Pluto-Charon system. Computer illustration of the dwarf planet Pluto (left) with its largest moon Charon (upper right) and the Sun (top right). Pluto has five known moons: Charon, Styx, Nix, Kerberos, and Hydra. Charon is a very rare large moon in comparison to its parent planet and the Pluto-Charon system is sometimes described as a binary system because the barycentre (centre of mass) of their orbits does not lie within either of them.
