HIP 41378, also known as K2-93, is an F-type star about 346 light-years away in the constellation Cancer. It hosts a system of five transiting planets discovered in 2016, and likely a sixth, non-transiting, planet. The outermost planet, HIP 41378 f, appears unusually large given its mass. While this may just indicate a very low density, it could also be evidence of a ring system, as depicted in this addon.
