Super Earth

A Super-Earth is an extrasolar planet, which has a mass greater than Earth. The term super earth refers only to the mass of the planet; it is not concerned about the surface conditions, orbital properties, environment and habitation within the planet. The first super-Earth was discovered by Aleksander Wolszczan and Dale Frail in the region of the pulsar PSR B1257+12 in 1992.
