Scientists have just discovered the "Godzilla of Earths" — a new type of huge and rocky alien world about 560 light-years from Earth. Dubbed a "mega-Earth," the exoplanet Kepler-10c weighs 17 times as much as Earth and it circles a sunlike star in the constellation Draco. The mega-Earth is rocky and also bigger than "super-Earths," which are a class of planets that are slightly bigger than Earth.
