(rocky planet ten times the size of Earth)

Mega-Earth is a term for a rocky planet (extra-solar planet) substantially larger than Earth. Generally, a threshold on the order of ten Earth masses is used as the minimum, i.e., it is an especially large super-Earth. The first planets to fit this description were found by Kepler.
