Alpha Centauri is a planetary system orbiting α Centauri, a G2V ☼ star in the Centaurus constellation of the Sol Region.
Alpha Centauri Alpha Centauri is a triple star system known for being the closest star system to Earth. The components of the system are 2 sun-like stars separated by an average distance of 24 AU, with a distant red dwarf companion 15,000 AU away.
The Alpha Centauri System contains multiple planets with the primary being Tellus (Alpha Centauri Bd). During the early years of space exploration on Earth, as telescope techonology improved an abundance of pontentially earth-like planets started being discovered. One of those planets lied in the Alpha Centauri system.
Probes sent to the system confirmed that the planet (Tellus) could support human life. The majority of the early manned missions to Alpha Centauri involved small groups of settlers, unlike missions sent to more distant systems which could involve 10's of thousands of colonists.
