Super-Neptune

A super-Neptune is an astronomical object that is more massive then 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 little discoveries of these kinds of planets, there are only a few known examples of such worlds. Such include Kepler-101b, HAT-P-11b, and K2-33b.^[2]^[3]
