'''Pluto (134340 Pluto)''' is a [[dwarf planet]] in the Kuiper Belt of the [[Solar System]]. It was disovered by [[w:Clyde Tombaugh|Clyde Tombaugh]] in February 1930. The dwarf planet is the ninth largest body that moves around the [[Sun]]. At first, Pluto was called a planet and is the largest body in the Kuiper belt.

Like other members of the Kuiper belt, Pluto is mainly made of rock and ice. It is quite small. It is about a fifth (⅕) of the weight of the [[Earth]]'s [[Moon]]. It is only a third (⅓) its volume. Pluto is very far from the Sun, so its temperature is very low. The average temperature on Pluto is -223 degrees Celsius. It has an [[w:orbital eccentricity|odd]] orbit and this orbit is very sloped. It takes Pluto to 30 to 49&nbsp;[[Astronomical unit|AU]] (4.4–7.4 billion&nbsp;km) from the Sun. This causes Pluto to sometimes go closer to the Sun than [[Neptune]].

At the time of its discovery, Pluto was considered a planet and was thought to be single body, but, in 1998 it was found to have a moon about half the radius of Pluto. In 2006, as part of the [[w:International Astronomical Union|International Astronomical Union (IAU)]] redefinition of planet and dwarf planet, henceforth, Pluto was reclassed as a dwarf planet.

Pluto's orbit is in a 3:2 resonance with that of [[Neptune]].

Pluto was first introduced with the release of ''pluto_pack.zip'' in July 2004.
