Alpha Centauri B

BASIC INFO

Alpha Centauri B is a Sun-like star located 4.37 light-years from Earth, part of the Alpha Centauri system, which also includes Alpha Centauri A and Proxima Centauri. Slightly smaller and cooler than Alpha Centauri A, it has about 90% of the Sun’s mass and is classified as a K-type star. Alpha Centauri B forms a binary system with Alpha Centauri A, and the two stars orbit each other every 80 years. While no confirmed planets have been found around Alpha Centauri B, the system is a prime target for planet-hunting missions, particularly for the search for Earth-like planets in the habitable zone.
