"A nearly Earth-size planet orbits in a star's habitable zone, detected by astronomers using NASA's Kepler Space Telescope. Launched in 2009 with the goal of finding another Earth, the $600-million Kepler spacecraft has discovered more than 960 planets orbiting nearby stars. Half a dozen of those seem to be rocky, like Earth, and have orbits in the habitable zone around their star, but the newly discovered world, named Kepler-186f, is the closest in size to Earth ~ Dan Vergano"
