Circe System

The Circe System features a small yellow sun and a single gas giant, Pero Prime.

Pero Prime has two moons, one of which is is barren and not hospitable, the other however, Pero II, is earth-like.

Pero I oribts Pero Prime incredibly slowly, and doesn't rotate around itself, meaning there is no day/night cycle. This means that mining operations are conducted on one side, and dome-farming on the other - of course, the moon undergoes an almost year long winter period where the farming relies on artificial lights and is barely profitable, but then it's summer again for another year.

Pero II rotates around itself and orbits around Pero fairly fast. Like with earth's moon, going through various phases of darkness, occasionally experiencing lasting night for small amounts of time.

Pero Prime is orbitted by Pero Prime Mining Station.

The two moons are accessible by their respective Orbital stations, Pero I Orbital Station and Pero II Orbital Station.
