HD 59686 A: A K-Type Giant With a Massive Minimum-Mass Planet
HD 59686 A is a K2 III star located 291 light-years away. Its reported mass estimate is 1.43 solar masses, its radius is 11.2 solar radii, and its temperature is 4670 K. The star is 2.73 billion years old.
One planet orbits this host. HD 59686 A b was discovered in 2016 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 2200 Earth masses, or roughly 6.92 times Jupiter's mass, and its orbital period is 299 days.
