NASA announced the discovery of a new habitable extra-solar planet Kepler-452b, which has the closest match of planet characteristics to Earth. Its host star has a spectral-type of G2, which is the same as the sun. We introduced the latest progress made by the Kepler telescope, and made a detailed explanation of the detection, validation, and habitability of Kepler-452b.
