Recently,NASA’s Kepler Space Telescope has discovered a similar planet like earth which is so close habitable zone of our galaxy. Kepler-186f is just about five hundred light-years from Earth within the Cygnus constellation.
The habitable zone, which is also referred to as the Goldilocks zone, is that the region around a star among that planetary-mass objects with ample atmospheric pressure which can support liquid water at their surfaces. whereas it's been calculable that there are a minimum of forty billion Earth-sized planets orbiting in our Milky Way System Galaxy, this amazing discovery is labelled the primary Earth-sized planet to be found within the habitable zone of another star.
