Kepler-443b is an exoplanet about 2,540 light-years from Earth.[2] It has an 89.9 percent chance of being in the star's habitable zone, yet only a 4.9 percent chance of being rocky.[1]
Characteristics
Mass, radius and temperature
Kepler-443b has a mass of 6.04 Earth masses,[3] a radius of 2.33 Earth radii and a temperature of 247 kelvin.
Host star
Kepler-443b orbits a K-type star called Kepler-443, 2541 light-years away.
Orbit
Kepler-443b takes 177.6693 days to orbit its star, with an inclination of 89.94°, a semimajor axis of 0.495 AU and an eccentricity of at least 0.11.
Habitability
Kepler-443b may be habitable, but the planet has only a 4.9 percent chance of being rocky. The planet is much more likely to be a water world or a Mini-Neptune.
