1 Ceres
From FenWiki
Ceres is the largest body in the Main Belt, and the only one to gain the status of dwarf planet. It is home to Port Ceres, a frontier town best known to visitors as a “truck stop and diner” facility. No one faction has control over Ceres; instead, it's administered by a democratically-elected council.
The astroball team Belt United is based out of Port Ceres.
