what is known as SUPER EARTH.

A super-Earth is an extra-solar planet(planet outside the Solar System ) with a mass higher than Earth's, but substantially below the mass of the Solar System's gas giants(Jupiter, Saturn, Uranus, and Neptune).

The term super-Earth refers only to the mass of the planet, and does not imply anything about the surface conditions or habitability. The alternative term "gas dwarf" may be more accurate for those at the higher end of the mass scale, as suggested by MIT professor Sara Seager.
