Alpha Centauri System

Alpha Centauri is a star system consisting of the binary pair Alpha Centauri A and Alpha Centauri B, plus the red dwarf Alpha Centauri C, which orbits the main pair. At an approximate distance of 4.3 light-years, Alpha Centauri is the closest neighbor to the Sol System, and appears as the brightest star in the constellation of Centaurus.

Alpha Centauri A, also known as Rigil Kentaurus, is a G-type yellow star, and the largest and brightest of the three. Alpha Centauri B, a.k.a. Toliman, is a K-type orange star, while Alpha Centauri C, as noted, is an M-type red dwarf, and better known by the name Proxima Centauri.

The system is inhabited by many alien species.
