Super-Earth

A super-Earth is an extrasolar planet.

It has a mass higher than Earth's, but much less than the Solar System's ice giants, Uranus and Neptune, which are 15 and 17 times Earth's mass, respectively.^[1]

The term "super-Earth" refers only to the mass of the planet, and does not imply anything about the surface conditions or habitability.
