Kepler-186b is an exoplanet orbiting the red dwarf Kepler-186 . The planet was discovered in 2014 by the Kepler space telescope.
Parent star
The parent star Kepler-186 is very faint, but also very active. It is a so-called flare star that tends to have strong prominences . The system is about 500 light years from Earth .
Location in the system
The planet is very close to its star in the star system and is the innermost planet of the star system. It is clearly not in the habitable zone , as it would be much too hot on the planet. It takes Kepler-186b less than four days to orbit its parent star.
