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.[3]
It is tidally locked. As a result, one hemisphere is in eternal daylight while the other hemisphere is in endless darkness.
The other planets in the system are Kepler-186c, d, e, and f. C is also not suitable for life. D isn’t good for life either. E is near to the star’s habitable zone but still deadly to life. All of the inner planets are tidally locked, but F is in the habitable zone.
