Super puff

A super-puff is a type of exoplanet with a mass only a few times greater than that of Earth , but a radius greater than that of Neptune . So it has a very low average density. Super puffs are cooler and less massive than the Hot Jupiter with their thermally expanded atmospheres.

The most extreme known examples are the three planets around Kepler-51 , all of which are Jupiter-sized.
