description Overview

Kepler-138b

Kepler-138b is a Mars-sized exoplanet orbiting the red dwarf star Kepler-138, located roughly 217 light-years away in the constellation Lyra. Confirmed in 2015 using data from the Kepler space telescope, it was one of the smallest exoplanets to have both its mass and radius directly measured. This measurement was made possible through transit-timing variations caused by gravitational interactions...

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...
