description Overview

Kepler-138c

Kepler-138c is a super-Earth exoplanet located in the Kepler-138 system, confirmed by NASA's Kepler space telescope in 2015. It orbits its M-dwarf host star every 13.8 days and is believed to be a water world, with a significant portion of its mass consisting of water. The planet orbits in near resonance with the adjacent Mars-sized companion Kepler-138b. Astronomers study this planet to understan...

Kepler-442b
