Charon (moon)
largest natural satellite of Pluto / From Wikipedia, the free encyclopedia
Charon is a moon of the dwarf planet Pluto. It is half as wide as Pluto and is much like the dwarf planet itself. It was discovered many years after Pluto. They are sometimes considered a binary system, as Charon does not orbit Pluto, and Pluto does not orbit Charon. They orbit a barycentre in space.[1]
