Gliese 12 b artist’s impression

An artist's impression of the newly-discovered, Earth-like exoplanet Gliese 12 b.
Gliese 12 b, which orbits a cool, red dwarf star located just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In this artist’s concept, Gliese 12 b is shown retaining a thin atmosphere.
