Alpha Centauri

Alpha Centauri is the closest star system to Sol, and the first to be colonised. Unlike most other stelar colonial efforts, Alpha Centauri was settled by a diverse multinational effort, giving it a unique culture. The triple star system is composed of two yellow dwarf stars (Alpha Centauri A and B) and a single red dwarf (Proxima Centauri). A single habitable planet, Proxima, is located in the orbit of Proxima Centauri while a debris disk is located in orbit around Alpha Centauri A and B.
