HD 68988 c is an exoplanet located approximately 192 light-years away in the constellation of Ursa Major, orbiting the star HD 68988. The parameters including period and eccentricity are highly uncertain. The semimajor axis was initially believed to be 5.32 AU with an orbital period of 4100 ± 7300 days (11 years).[2][3] The planetary orbit was significantly refined in 2021.[1]
