The Alpha Centauri system (α Cen, α Centauri, Rigel–Toliman) is a star system located in the Solar Sector. It is part of the Greater Centauri system along with the Proxima Centauri system, the latter also known as "Alpha Centauri C". It was first colonized in 2090 by the North Atlantic Conglomerate and United Republics of Bharat, comparably much later than its sibling system.

Etymology

The name α Centauri (Latinised to Alpha Centauri) is the system's Bayer designation, being the brightest star in the constellation Centaurus. The common name of α Centauri A, Rigel, comes from Rigil Kentaurus, a Latinisation of the Arabic translation رجل القنطورس Rijl al-Qinṭūrus, meaning "the Foot of the Centaur". Before the interstellar age, this name was more commonly known for the star Rigel (β Orionis). Following this theme, all of the planets in the Rigel system are named after names of body parts in Arabic.

The name of α Centauri B, Toliman, is an approximation of the Arabic الظليمان aẓ-Ẓalīmān (in older transcription, aṭ-Ṭhalīmān), meaning 'the (two male) Ostriches', an appellation Zakariya al-Qazwini had applied to the pair of stars Lambda and Mu Sagittarii.
