description Overview

Kepler-10c

Kepler-10c is a transiting exoplanet orbiting Kepler-10, a Sun-like star also known to host the rocky planet Kepler-10b. With a radius of about 2.35 times Earth's, it was initially described as a massive, potentially rocky "mega-Earth" after an early mass estimate near 17 Earth masses. Later measurements yielded a lower and less certain mass, weakening the original rocky interpretation and making...

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...
