Cousin of the Earth - Kepler -186f

 In search of planets like Earth which will be habitable for humans, we have discovered many planets, one of such planet is Kepler-186f. Kepler-186f is an exo-planet (which is outermost of five planets in the habitable zone of Kepler-186f[Red dwarf star] ) which was founded in 2015 by Kepler telescope and this planet is located about 580 light years away from Earth in Cygnus constellation.

Kepler-186f orbits it's star around a period of 130 Earth days but the key components of the habitable planets such as atmosphere, water hasn't been determined yet but still the habitability of this planets is as similar as Earth.

The discovery of Kepler-186f confirms that Earth size planets exits in the habitable zone of other stars and this bring humans closer to finding life beyond Earth.
