Pluto

==Overview==
Originally considered the ninth planet of the solar system, Pluto is now considered a dwarf planet after a decision by the IAU in 2006, along with Ceres, Haumea, Makemake, and ErisThis article was adapted from the Space Engine ingame wiki. 
==Composition and Atmosphere==
Pluto is thought to consist of roughly 60% rock and 40% ice, mostly nitrogen ice as determined by spectroscopic analysis, with traces of methane and carbon dioxide ices. Pluto also periodically holds a thin atmosphere, created by the sublimation of surface ice as it nears perihelion. This sublimation of ice also has the effect of altering its appearance over the course of a single orbit.
==Moons ==
Pluto has five known moons. The largest of these, Charon, is so large that it and Pluto form a binary system - both orbiting a common center of mass between the two objects. The other four moons are small asteroidal bodies all orbiting beyond Charon. From innermost to outermost, they are: Styx, Nix, Kerberos, and Hydra.
== Orbit==
Pluto's orbit is normal for a Kuiper Belt Object, with a semi-major axis of 39.26 AU, an inclination of 17°, and an eccentricity value of 0.248.
