This trinary star system is located in the Centaurus constellation, and is the third brightest stellar object in the night sky. The Alpha Centauri star system is made up of three stars (trinary star system), Alpha Centauri A (Rigil Kentaurus), Alpha Centauri B (Toliman), and Alpha Centauri C (Proxima Centauri). Of these three, all are present in the game. These are a main-sequence star of spectral type G2V (Rigil Kentaurus), main-sequence star of spectral type K1V (Toliman), and a small main-sequence red dwarf star of spectral type M5.5Ve (Proxima Centauri).
Rigil Kentaurus and Toliman orbits around each other: their gravity is nearly the same so the barycenter is in neither star - instead, it is around a barycentre in the middle of space between the two stars. It takes around 79 years for the pair of stars to rotate. Proxima Centauri also orbits the barycentre, but can orbit as far as 13,000 AU (0.21 light-years) and take around 550,000 years to complete one orbit.
The Alpha Centauri system is famous for being to closest star system containing the closest stars to the Sun, as well as containing a rare type of star - a G-type star, which our Sun and Rigil Kentaurus are part of.

=== Planets ===
==== Proxima Centauri (Alpha Centauri C) ====
There are three confirmed exoplanets orbiting our red dwarf star neighbor; all three are in the game. These are designated Proxima Centauri b, Proxima Centauri c, and Proxima Centauri d. 
===== Proxima Centauri b =====
Proxima Centauri b is a terrestrial planet (like Mercury, Venus, Earth & Mars) sitting in the habitable zone of the star. It is one of the closest habitable exoplanets we've ever found and takes 11.2 Earth days to orbit Proxima. It is not known whether an atmosphere is present or not, or if that Proxima has stripped it away due to its intense solar flares.
===== Proxima Centauri c =====
Proxima Centauri c could be a super-Earth or mini-Neptune. It might also have a ring system. Its existence is very controversial on whether it even exists or not. It takes 5.28 years to orbit Proxima, and is incredibly cold.
===== Proxima Centauri d =====
Proxima Centauri d is a sub-Earth at least one-quarter of the mass of Earth. It takes 5.2 days to orbit Proxima and might contain habitable polar ice caps similar to Mars.
