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...

Gliese 581 c

Gliese 581 c is a super-Earth exoplanet discovered in 2007 orbiting the red dwarf star Gliese 581, located about 20 light-years from Earth. Upon its discovery via the radial velocity method, it was considered a candidate for habitability due to its location near the star's habitable zone. However, subsequent scientific analysis suggests that the planet likely suffers from a runaway greenhouse effe...
