The term sub-Neptune can refer to two different types of planets. It may describe a planet that has a smaller radius than Neptune, even if that planet actually has a larger mass. Alternatively, it can describe a planet with a smaller mass than Neptune, even if that planet has a larger radius (like a super-puff planet). Both definitions are sometimes used within the same scientific publication.
