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 REarth) for a planet of its size and temperature, therefore the radius may actually be that of an optically thick ring system.[2] It is located within the optimistic habitable zone of its parent star.[3] No atmospheric signatures were found as in 2022, further reinforcing the hypothesis of opaque circumplanetary rings.[4]
