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-47b

Kepler-47b is a transiting circumbinary exoplanet located in the Kepler-47 system, which was announced in 2012. It was part of the first system discovered to host multiple planets orbiting a binary star pair. The planet completes an orbit around the two host stars approximately every 49 days. It is slightly larger than Uranus, placing it in the Neptune-class category of exoplanets.
