Planetary system
In 2016, the K2 Kepler mission discovered five planets around HIP 41378, with sizes ranging from 2 times the size of Earth to the size of Jupiter, out to about 1 AU for the outermost planet. The semi-major axes were not known until K2 Haute-Provence Observatory radial velocity data was obtained in 2019. Also, a sixth non-transiting planet, HIP 41378 g, was discovered, along with speculation that additional planets may exist between HIP 41378 g and HIP 41378 d. The planet HIP 41378 f was also found to likely have optically-thick rings or a highly extended atmosphere.
