'''Pluto''', formal designation '''134340 Pluto''', is a dwarf planet in the [[Sol system]], and the second-largest known dwarf planet (after [[Wikipedia:Eris (dwarf planet)|Eris]]) as well as the tenth-largest body observed directly orbiting Sol. It was named after the Roman God of the Underworld. The [[Remote Scanning Outpost]] ''[[Democritus]]'' is situated in orbit over this dwarf planet.

==History==
==History==
Pluto was discovered during 1930, and was then thought to be the ninth and final planet of the Solar System. Its first moon, Charon, was discovered during 1978. During 2005, two smaller moons were discovered. During 2006, arguments began to arise on whether Pluto was actually large enough to be considered a planet. After much debate, Pluto (along with the asteroid Ceres and the object Eris) became newly classified as dwarf planets.
Pluto was discovered in the early 20th-century. It was originally considered a [[planet]] and thought to be causing issues in [[Neptune]]'s orbit but was then downgraded to a dwarf planet when Pluto was determined to be ill-suited for that.{{Ref/Reuse|enc295}}

Pluto is a diminutive planetoid in the Sol system.[1]

Overview

There are no facilities on the dwarf-planet's surface; however, several military and scientific stations orbit Pluto,[1] including the Kelvin Research Station,[2] UNSC Monitoring Station Delta Five,[3] and the remote scanning outpost, Democritus.[4]

History

Pluto was discovered in the early 20th-century. It was originally considered a planet and thought to be causing issues in Neptune's orbit but was then downgraded to a dwarf planet when Pluto was determined to be ill-suited for that.[1]
