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-22b

Kepler-22b is an exoplanet orbiting a G-type star similar to our Sun. Discovered by NASA’s Kepler mission in 2011, it resides within its star's habitable zone, the region where liquid water could potentially exist on a planet’s surface. This “super-Earth,” roughly 2.4 times Earth’s size, is notable as one of the first confirmed planets in this zone and offers scientists an opportunity to study pot...
