description Overview

GJ 357 b

GJ 357 b is a transiting exoplanet with a radius about 1.2 times Earth's, discovered through NASA's TESS observations of the nearby M dwarf GJ 357. It is the innermost of three known planets in the system and completes an orbit in about 3.9 days. Its estimated equilibrium temperature is roughly 525 K, or about 250 degrees Celsius, so it receives too much irradiation to be considered a temperate or...

K2-3 d

K2-3 d is a transiting exoplanet orbiting K2-3, a nearby cool M-dwarf star. It was identified from observations by NASA’s K2 mission and has a radius in the super-Earth range, larger than Earth but smaller than Neptune. Its orbital period is about 45 days, placing it near the region where temperatures may permit liquid water under suitable atmospheric conditions, although the planet’s actual atmos...
