Charon is the largest natural satellite of [[Pluto]]. It is so large compared to Pluto, that its barycentre lies outside both objects. This is a common definition of a binary object, leading some astronomers to consider them a [http://en.wikipedia.org/wiki/Double_planet double dwarf planet].

Charon is the largest natural satellite of Pluto. Its radius is about half that of Pluto, and their barycentre lies outside both objects. This is a common definition of a binary object, leading some astronomers to consider them a double dwarf planet.

Charon was discovered in 1978 by James W Christy.

From the discovery of Nix and Hydra, it was possible to estimate Charon's mass as roughly 10% that of Pluto. This implies it's approximately 45% ice, thought mostly to be water ice.

Charon was introduced to Orbiter with the release of pluto_pack.zip in July 2004.
