Pluto

See Pluto on Wikipedia.

Pluto is an icy dwarf planet in the Sol system, located in the Kuiper belt, a ring of celestial bodies extending beyond the orbit of Neptune. It was the first and largest Kuiper belt object to be discovered.

It is loosely governed by the Sol Defense Corps, being used as a military outpost for the SDC Navy's 4th Poseidon Fleet.

Colonization
Up until the SDC's first touchdown on the dwarf planet's surface in 2080, Pluto remained largely ignored by the general public. Samples of water-ice in Pluto's mountains were discovered during initial exploration efforts, sparking interests in colonization.

However, the idea of establishing a colony was quickly shot down by the United Nations due to humanitarian concerns. Other organizations, such as Gansai Industries expressed interest in establishing a mining operation on the dwarf planet, but such plans never came to fruition.

After some internal political debate, the United Nations allowed the Sol Defense Corps' 4th Poseidon Fleet to establish a military outpost on the dwarf planet's surface, making use of artificial gravity generators and atmospheric control systems to create habitable environments.

Within 6 months, the outpost was established and the operation was considered a success, allowing the Poseidon Fleet ease of access to conduct repairs, upgrades, and staffing changes to their vessels, with the 4th Poseidon Fleet acting as Sol's border guard.
