HIP 41378 f
HIP 41378 f (also known as EPIC 211311380 f) is an exoplanet orbiting around the F-type star HIP 41378. It has an anomalously large radius (9.2 R⊕) for a planet of its size and temperature, therefore the radius may actually be that of an optically thick ring system.[2][3] Located within the habitable zone of its parent star, HIP 41378 f may harbor a habitable exomoon.
