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...

GJ 357 d

GJ 357 d is a confirmed, non-transiting super-Earth orbiting the M-dwarf GJ 357. Its minimum mass is about 6.1 Earth masses, and its orbital period is approximately 56 days, placing it near the outer part of the system. The planet receives much less stellar energy than Earth and has been described as potentially within the host star’s habitable zone, although that interpretation depends on its atm...
