Description
NASA’s Kepler Space Telescope recently discovered an Earth-like planet orbiting a nearby star within the habitable zone of our galaxy.
Kepler-186f is approximately 500 light-years from Earth in the Cygnus constellation.
The habitable zone, also known as the Goldilocks zone, is the region around a star within which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their surfaces. While it has been estimated that there are at least 40 billion Earth-sized planets orbiting in our Milky Way Galaxy, this particular discovery is labeled the first Earth-sized planet to be found in the habitable zone of another star.
