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 edit

Mass, radius and temperature edit

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]

Host star edit

Kepler-443b orbits a K-type star called Kepler-443, 2541 light-years away.^[2]

Orbit edit

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.^[2]

Habitability edit

Kepler-443b may be habitable, but the planet has only a 4.9 percent chance of being rocky.^[1] The planet is much more likely to be a water world or a Mini-Neptune.
