Verrier Belt
Galactica
Can be home to characters.
While there are extensive mining operations on the multitude of asteroids in the Verrier Belt, there are very few permanent habitats here, due to the difficulty of getting supplies out to the Belt - particularly water and oxygen.
Still, there are those who live here - primarily space pirates. 'Live' might be a strong word - they tend to subsist in stolen ships between raids out here. While orbital stations and domes on moons have defenses against them, ships plying the system do not always. Of course, things go poorly for them when they encounter the Galactica Guards' ships... but space is a vast place...
