Alpha Centauri is host to two sun-like stars, and a third star – the red dwarf Proxima Centauri, which is already believed to have one planet in a Goldilocks orbit, discovered in 2016.

Alpha Centauri is also the very closest system in the galaxy, lying just 4.37 light—years away and providing a uniquely intimate perspective on any possible planets there.
