Planet HD 86950 b and Its K-Type Giant Host
HD 86950 is a K1 III star 684 light-years away with one known planet. The star has a mass of 1.66 solar masses, a radius of 8.8 solar radii, and a temperature of 4810 K. Its mass and radius are larger than the Sun's, while its temperature is cooler.
The one planet orbiting HD 86950 is HD 86950 b, discovered in 2016 by radial velocity, a method that detects the wobble a planet's gravity induces in its star. It has a minimum mass of 1140 Earth masses, larger than Earth's, and roughly 3.6 times Jupiter's mass. This minimum mass is a lower bound on the planet's true mass. Its orbital period is 1270 days.
