Extra Solar Planets

A type M1 dwarf star, Kepler-186 is approximately 492 light years away. At 3788K, it is somewhat cooler than the Sun (5,772K).  It has about 48% the mass of our Sun, and is categorized as a BY Draconis variable.  To date, five planets have been identified including the first Earth-sized planet lying in the habitable zone.  The discovery of the four inner planets was confirmed in February 2014.  Masses of the planets has yet to ne determined.
