Alpha Centauri Stellar System

At 4.3 light-years away, Alpha Centauri A and B are the nearest Sun-like stars to our solar system. They orbit with Proxima Centauri as a triple star system.

Alpha Centauri A is a Class G star that is 1.1 times the mass of the Sun. Alpha Centauri B is slightly cooler Class K star that is 0.9 times the mass of the Sun. Proxima Centauri, the closest star to the Sun, is a much smaller and cooler star, called a red dwarf.

While no planets have been found around Alpha Centauri A or B, Proxima Centauri has two confirmed planets.
