description Overview

Kepler-138d

Kepler-138d is a transiting exoplanet orbiting the M-dwarf star Kepler-138 approximately 200 light-years from Earth. It is the outermost of three known planets in the system, completing an orbit every 23.1 days. Categorized as a super-Earth, its mass and radius suggest a low bulk density. Researchers propose that this low density implies a substantial volatile envelope, leading to classifications...

Kepler-1649c

Kepler-1649c is an exoplanet roughly Earth-sized orbiting a red dwarf star named Kepler-1649. Its location within its star’s habitable zone—the region where liquid water could exist on the surface—makes it notable. Scientists study this super-Earth to assess the potential for habitability around M-dwarf stars and understand planetary formation processes. The planet is of interest to researchers in...
