'''Pluto''' is a [[Dwarf Planet|dwarf planet]], the largest ''Plutino'' and a ''trans-Neptunian object'' in the outer [[solar system]]. Pluto used to be considered the ninth planet, but  on 24 August 2006 astronomers voted to reclassify it[http://news.bbc.co.uk/1/hi/world/5282440.stm].

Pluto is a dwarf planet in the Solar System.[1] Its formal name is 134340 Pluto. The dwarf planet is the ninth largest body that moves around the Sun. At first, Pluto was called a planet. Now, it 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 odd orbit and this orbit is very sloped. It takes Pluto to 30 to 49 AU (4.4–7.4 billion km) from the Sun. This causes Pluto to sometimes go closer to the Sun than Neptune.

Pluto is not included in the standard Orbiter distribution, but an addon can be downloaded from Orbithangar.[2]
