Moons of Pluto

The dwarf planet Pluto has five known moons. In order of distance from Pluto they are Charon, Styx, Nix, Kerberos, and Hydra. Charon, the largest of the five moons, is mutually tidally locked with Pluto, and is massive enough that Pluto–Charon is sometimes considered a double object.

NOTES (Real world)[1] The New Horizons mission is scheduled to visit Charon and Pluto in July 2015. It will flyby the Pluto system and then continue its journey to interstellar space.
 * Charon, once called (134340) Pluto I ] is the largest satellite of the dwarf planet Pluto. It was discovered for Earth in 1978 at the United States Naval Observatory Flagstaff Station (NOFS). It is a very large moon in comparison to its parent body, Pluto. Its gravitational influence is such that the barycenter of the Pluto–Charon system lies outside Pluto.
 * Styx is a small natural satellite of Pluto whose discovery was announced on 11 July 2012. It is the fifth confirmed satellite of Pluto and was found approximately one year after Kerberos, Pluto's fourth confirmed satellite. Styx is estimated to have a diameter of between 10 and 25 kilometers (6 and 16 mi), and an orbital period of 20.2 days.
 * Nix is a natural satellite of Pluto. It was discovered along with Hydra in June 2005, and is to be visited along with Pluto by the New Horizons mission in July 2015.
 * Kerberos is a small natural satellite of Pluto whose existence was announced on July 20, 2011. Its discovery, following the discoveries of Charon in 1978 and Nix and Hydra in 2005, made it Pluto's fourth known moon.
 * Hydra is the outermost known natural satellite of Pluto. It was discovered along with Nix in June 2005, and is to be visited along with Pluto by the New Horizons mission in July 2015.
