Super-Earth

(exoplanet more massive than Earth but substantially less than Neptune)

Super-Earth is a common term for Extra Solar Planets more massive than the Earth but substantially less massive than Uranus and Neptune, basically 2-10 Earth masses though there is no consensus on exact limits.

The term generally is used whatever its properties and they've generally been found to have large Atmospheres like Gas Giants. Some use the term specifically to refer to Rocky Planets like Earth and use other terms, such as Mini Neptune, Gas Dwarf, or Transitional Planet for planets with large atmospheres in the manner of Neptune, etc.
