proxima centauri b (also called proxima b or alpha centauri cb) is an exoplanet orbiting in the habitable zone of the red dwarf star proxima centauri, which is the closest star to the sun and part of a triple star system. it is located about 4.2 light-years (1.3 parsecs, 40 trillion km, or 25 trillion miles) from earth in the constellation of centaurus, making it the closest known exoplanet to the solar system.

a candidate second planet orbiting proxima centauri was reported by italian astrophysicist mario damasso and his colleagues in april 2019. damasso's team had noticed minor movements of proxima centauri in the radial velocity data from the eso's harps instrument, indicating a possible additional planet orbiting proxima centauri. dubbed proxima c, the exoplanet is estimated to have a minimum mass of six times that of earth. it is expected to orbit proxima centauri at a distance of 1.5 au, with an orbital period of roughly 1900 days, or about 5.2 years. due to its large distance from proxima centauri, the exoplanet is unlikely to be habitable, with a low equilibrium temperature of around 39 k. additional observations and measurements from the harps instrument and the european space agency's "gaia" spacecraft are needed to verify the existence of the possible exoplanet. del sordo of damasso's team states that proxima c could provide opportunities for further observations of the proxima centauri planetary system, especially by direct imaging.
