Basis

Moon Diameter: 23,848km Star Name: Soell

Summary
Politically nonalligned, Basis is the largest moon orbiting Threshold. Installation 04 was positioned between Basis and Threshold. After Installation 04's destruction, the Covenant heretics built a makeshift camp on Basis, amid the wreckage from the Alpha Halo.

While often thought to be the location of the Gas Mine, this is in fact Threshold. Basis is, however, the location of the Halo 2 multiplayer level Burial Mounds.
