NASA Discovers Larger, Older Cousin to Earth
NASA's Kepler mission has confirmed the first near-Earth-size planet in the "??habitable zone"?%9D around a sun-like star. The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone - the area around a star where liquid water could pool on the surface of an orbiting planet - of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030. This video shows an artist's concept that depicts one possible appearance of the planet Kepler-452b.
