Kepler-443b is an exoplanet about 2,540 light-years from Earth.[2] Kepler-443b orbits a K-type star called Kepler-443.[2] It takes 177.6693 days to orbit, with an inclination of 89.94°, a semimajor axis of 0.495 AU, and an eccentricity of at least 0.11.[2]
Kepler-443b has a mass of 6.04 Earth masses,[3] a radius of 2.33 Earth radii,[2] and a temperature of 247 kelvin.[2] This planet has an 89.9 percent chance of being in the star's habitable zone.[1] Kepler-443b may be habitable, but the planet has only a 4.9 percent chance of being rocky.[1] It is much more likely to be a water world or a mini-Neptune.
