Super-Neptune

A super-Neptune is an astronomical object that is more massive than the planet Neptune. These planets are generally described as being around 5–7 times as large as Earth with estimated masses of 20–80 M⊕,[1] beyond this they are generally referred to as gas giants.

There have been relatively few discoveries of these kinds of planets. Known examples include Kepler-101b, HAT-P-11b, and K2-33b.[2][3]
