GJ 357 c

Exoplanet Warm Radial Velocity Super Earth Multi Planet M Dwarf

GJ 357 c is a confirmed exoplanet orbiting the nearby M-dwarf star GJ 357. It is classified as a super-Earth and is non-transiting, so its presence was inferred from the star's radial-velocity variations rather than a visible passage across the stellar disk. Announced in 2019 with GJ 357 b and GJ 35...
