Description
The Alpha Centauri triple system is the closest star system to us. The system has three stars, they are Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Alpha Centauri A and Alpha Centauri B are sun-like stars that orbit each other, meanwhile Proxima Centauri is a small red dwarf that is too dim to be visible from Earth without a telescope. Alpha Centauri A is thought to have a planet larger than Neptune orbiting it, but we still don't know for sure if it exists or not. Alpha Centauri B was thought to host 2 planets, Alpha Centauri Bb and Alpha Centauri Bc. But more recent studies disprove the existence of Alpha Centauri Bb. Proxima Centauri has 3 known planets so far although the existence of one of them, Proxima Centauri C, is still controversial. But one of the other planets, Proxima Centauri B, is most likely a super earth with very habitable conditions for life.
