description Proxima Centauri c Overview
Proxima Centauri c is a proposed planet candidate orbiting Proxima Centauri, the nearest known star to the Sun. The candidate was announced in 2020 from a combination of radial-velocity and astrometric evidence and was estimated to orbit at roughly 1.5 astronomical units. Its inferred orbit would place it in a cold region, far beyond the star's habitable zone. The planet's existence and properties remain less secure than those of Proxima b.
