    Kepler-186b is the innermost planet of its system, and thus not suitable for life. One year on the planet is only 3.884 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, of which only Kepler-186f is habitable.

    Kepler-186b es un exoplaneta perteneciente a la constelación de Cygnus, a una distancia de 492,5 años luz de la Tierra.[1] Su hallazgo se confirmó en 2014, después de que el telescopio espacial Kepler detectase varios tránsitos del objeto frente a su estrella.[2] Su radio es un 14 % mayor que el de la Tierra, muy por debajo del límite teórico establecido por los expertos que separa a los cuerpos terrestres de los de tipo gaseoso. Por tanto, la probabilidad de que se trate de un planeta telúrico es muy elevada.[3][1]
