Proxima Centauri b is an exoplanet in the habitable zone of the closest star to the Sun, part of the Alpha Centauri system. It was discovered in 2016 by studying the radial velocity of the star and has a minimum mass of 1.07 M🜨 and a possible Earth-like size.
Proxima Centauri is a red dwarf star that is likely a part of the Alpha Centauri star system and is the closest star to the Sun at a distance of 4.22 light-years (3.99 × 10 13 km; 2.48 × 10 13 mi). It is in the constellation of Centaurus .
Proxima Centauri b is a super Earth exoplanet that orbits an M-type star. Its mass is 1.07 Earths, it takes 11.2 days to complete one orbit of its star, and is 0.04856 AU from its star. Its discovery was announced in 2016.
Proxima Centauri is very likely the third component of the Alpha Centauri system, but the star’s orbital period may be more than 500,000 years. Proxima Centauri is a red dwarf, too faint to be seen with the unaided eye. It has an apparent magnitude of 11.05. It was discovered by the Scottish astronomer Robert Innes in 1915.
