'''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.
