Ceres (designated 1 Ceres) is the largest asteroid known and the only dwarf planet in the inner solar system, and the first asteroid discovered by humanity. It lies in the Asteroid Belt.
Ceres is the site of Ceres station, a space station that was one of the first sites of human colonization. Two hundred fifty kilometers in diameter with tens of thousands of kilometers of tunnels, it has a spin of 0.3g.
As the most important port in the Belt, the station has a population of approximately six million permanent residents with an extra one million transiting through.
Ceres station security was handled by the private security firm Star Helix Security. After the Eros incident, governorship of the station was given to OPA.
