Humans had established an outpost in the Alpha Centauri system by the early 22nd century. Among its residents during this time was warp drive developer Zefram Cochrane, who moved to the system from Earth sometime following his historic test flight of the Phoenix in 2063. He left the system in 2119 for an unknown destination. He was presumed dead in space. (TOS: "Metamorphosis")

Background

 * The Alpha Centauri colony is believed to have been a founding member of the United Federation of Planets, along with Earth, Andoria, Tellar, and Vulcan.


 * As of 2024, Human scientists haven't figured out if Proxima Centauri is orbiting Alpha Centauri A and B or just passes them.
