description Overview

Proxima Centauri c

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...

Proxima Centauri b

Proxima Centauri b is an exoplanet orbiting Proxima Centauri, the closest star to our Sun. This super-Earth resides within its star’s habitable zone, raising possibilities for liquid water on its surface. Its proximity makes it a key target for astronomical study and future investigation by scientists examining potentially habitable worlds beyond our solar system.
