Kepler 452b, "Earth 2.0," isn't the first roughly Earth-size planet found in a star's habitable zone: but the star, Kepler 452, is remarkably similar to our sun. Another planet, HIP 11915b, is the first we've found that's around Jupiter's size: and orbiting its star at about the same distance as Jupiter. This is the first other planetary system that 'looks like' our Solar system.
