Alpha Centauri…astrologically speaking, Alpha Centauri is the closest solar system to the Sol System at a measly 4.4 light years away. Heck, Alpha Centauri is far closer than twelve parsecs away…in fact it’s about one and a third parsecs away. Alpha Centauri is a binary system, and according to Xavier Dumusque, the discoverer of the world, “it will surely be the closest one ever.” It also circles Alpha Centauri B, the red star orbiting Alpha Centauri A, which is the primary planet.
Unfortunately, Alpha Centauri Bb, as the planet is known, is not habitable. It has a surface temperature of about 1,200F.
It is unclear if the Alpha Centauri system is a binary or trinary star system. There is speculation that Alpha Centauri A, Alpha Centauri B and Proxima Centauri are in a complex system, but it has not been proven or disproven yet.
Accurding to Dumusque “Very small planets are not rare. When you find one small planet, you find others.”
