  • Charon is the largest satellite of the dwarf planet Pluto. It was discovered in 1978 at the United States Naval Observatory Flagstaff Station. Following the 2005 discovery of two other natural satellites of Pluto, and two more in 2011 and 2012, Charon may also be referred to as Pluto I. The New Horizons mission is scheduled to visit Charon and Pluto in July 2015.
