New Sol was chosen as the new home for humanity when Sol went nova.
The system contains six planets and one planetoid - in order: Midas, Volcan, Terra Nova, Lasair, Atla, Lilith, and The Rock.
Volcan, Terra Nova, and The Rock are the only continuously inhabited planets in the system. Volcan supports a small colony of Mahlok, while Terra Nova supports the bulk of humanity. The Rock is a prison planetoid, operated by CONON.
