Mixus-1

Mixus-1
Mixus-1 has one planet just slightly larger than Earth. The planet orbits a binary star system, the primary star, a red dwarf, has 5 planets, whereas the secondary star, a white dwarf, has only 1. The binary is safe, however, as the white dwarf orbits at an average distance of around 1000 AU, and is likely a captured dwarf.

Mixus A-
Mixus A is a M-3 Red Dwarf. It was born roughly 5.9 billion years ago, and is a non-flare star. It is thought to have once had an extra gas giant, probably Saturn-sized. However, it may have orbited 800-900 AU away, and was destroyed by the white dwarf. Mixus A is thought to have a violent history.

Mixus B-
Mixus B is a captured white dwarf, as it's age suggests it is around 11 billion years old. It is small, cool, and dim for a white dwarf. It is not visible from any of the planets around Mixus A, as it would be around the 7th magnitude on a dark night at perihelion on Mixus Ae. However, the planet is has would see the star at around -23rd magnitude. On the contrary, Mixus A looks around magnitude 5.7 at Mixus Ba.

Planets-

 * Mixus Ab- Mixus Ab is a small, Europa-sized planet. In fact, it is tidally locked to it's star. It is exactly 245 F on the daytime side, and 215 F on the nighttime side, making clouds form at the poles, and hot liquid water at the northern most areas and craters, where it is around 195-203 F. Around it's equator it can get as hot as 310 F.
 * Mixus Ac- Mixus Ac is 1.1344876625 the size of Earth, and it is extremely odd- Whereas it is around 95 F globally, it's oceans lie right next to the 'land', which is in fact, mostly lava. Volcanoes are common. It is not tidally locked, but is nearly so, as it's day, 12 days long, nearly matches it's 15 day year. It is not likely to become a Venus, as many CO2-related molecules escape the weak atmosphere frequently, as it is around 13%-30% as strong as Earth's. It is believed the Mixus Ac is cooling down from a recent collision with a small protoplanet or planetismal. It is also currently migrating outward, so it will eventually chill to around 12 F. By this point, in around 700 million years, the volcanoes will have died down. Accounting for the thicker atmosphere it will accumulate, around 60% of Earth's, it may stay as warm as 35-50 F. Continents are in the process of forming on Mixus Ac, and the conditions are nearly correct for it to host life. It has many organics in it's deep oceans.
