HIP 41378 f (also known as EPIC 211311380 f) is an exoplanet orbiting around the F-type star HIP 41378. It is the outermost planet of its system. It has an anomalously large radius (9.2 ) for a planet of its size and temperature, therefore the radius may actually be that of an optically thick ring system. It is located within the optimistic habitable zone of its parent star. No atmospheric signatures were found as in 2022, further reinforcing the hypothesis of opaque circumplanetary rings.
