Charon , also known as (134340) Pluto I , is the largest of the five known natural satellites of the dwarf planet Pluto . It was discovered in 1978 at the United States Naval Observatory in Washington, D.C. , using photographic plates taken at the United States Naval Observatory Flagstaff Station (NOFS). With half the diameter and one eighth the mass of Pluto, it is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Pluto–Charon system lies outside Pluto. In September 2016, astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins , organic macromolecules that may be essential ingredients of life , and produced from methane , nitrogen and related gases released from the atmosphere of Pluto and transferred over about 19,000 km (12,000 mi) distance to the orbiting moon. [10] The New Horizons spacecraft is the only probe that has visited the Pluto system. It approached Charon to within 27,000 km (17,000 mi) in 2015. |

Charon ( shar'-ən or karr'-ən , Greek Χάρων ) is the largest satellite of Pluto . It was discovered by astronomer James Christy on June 22 , 1978 by carefully examining highly magnified images of Pluto on photographic plates taken a couple of months before and noticing that a slight bulge appeared periodically. Later, the bulge was confirmed on plates dating back to April 29 , 1965 . It received the temporary designation S/1978 P 1 , according to the then-recently instituted convention. It is not to be confused with the similarly named 2060 Chiron , another object in the outer solar system with an orbit between those of Saturn and Uranus . With the discovery in 2005 of two other moons of Pluto ( S/2005 P 1 and S/2005 P 2 ), Charon is now also referred to as Pluto I . |

Charon was discovered by astronomer James Christy in 1978 using photographic plates which showed a bulge moving around Pluto. Christy named it after the Greek mythological figure Charon but pronounced it differently. The "ch" at the beginning of the moon's name is soft so it sounds like "Sharon," after the astronomer's wife Charlene, nicknamed Char, which both have soft ch sounds. The mythological figure's name is pronounced with a hard "ch" sound like the modern letter "k" (or more properly like the German "ch" in "Bach"), like in Christy's name. |
