A G2-type star (Kepler 452), the same class as the Sun, harbors the planet Kepler-452b. The planet is 60 percent larger than Earth and receives 10 percent more energy from its Sun than the Earth.

Kepler-452b size is important because it receives 10 percent more energy from its Sun than we do from ours. That mass protects it from experiencing "runaway greenhouse effect and the loss of its water inventory," according to NASA.
