Kepler 186b (also known as KOI-571.03) is an exoplanet located around 582 light-years away from Earth. Kepler-186b is orbiting a red dwarf known as Kepler-186, named after the space telescope that found it.[3]

Kepler-186b is the innermost planet of its system, and thus not suitable for life. One year on the planet is only 4 days long due to its location near the parent star.[4]

It is tidally locked. As a result, one hemisphere is in eternal daylight while the other hemisphere is in endless darkness.
