Triton (Sol 8a)

Triton is a moon of Neptune (Sol VIII), United Empire of Earth (UEE). The largest of Neptune's moons, it the planet's only natural satellite massive enough to have achieved gravitational rounding. Additionally, even though it is a moon, it is larger than all other dwarf planets in the Sol system, one of many factors that has led scientists to hypothesize that it was captured from the nearby Kuiper belt (Sol belt beta) by Neptune's gravity.
