Alpha Centauri is actually a triple star system, meaning it consists of three stars:
* Alpha Centauri A (also known as Rigil Kentaurus)
* Alpha Centauri B (also known as Toliman)
* Proxima Centauri
Proxima Centauri is the closest star to our Sun, and it is a red dwarf star that orbits Alpha Centauri A and B. It's part of the same system, but it's not the same star as Alpha Centauri.
