HD 184010, also known as HR 7421 and HIP 96016, is a single K0III giant star about 200 light-years away in the constellation Vulpecula. A system of three giant planets was discovered orbiting this evolved star via the radial velocity method in 2022. The planets have minimum masses of approximately 0.31, 0.30, and 0.45 times that of Jupiter, with orbital periods of 286.6 days, 484.3 days, and 836.4 days, respectively. This system is unique as the first discovered around a highly evolved star to host more than two giant planets with intermediate orbital periods.
