HD 6860 b: A Giant Planet Orbiting a Cool Giant Star

HD 6860 is a single star 199 light-years away with one known planet. The host is an M0 III star, a cool giant with a reported mass of 2.49 solar masses, a radius of 86.4 solar radii, and a temperature of 3800 K. Its mass estimate is larger than the Sun's, its radius estimate is larger than the Sun's, and its temperature is cooler than the Sun's.

The planet HD 6860 b was discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 8980 Earth masses, a lower bound on its true mass, and an orbital period of 664 days. That minimum mass is larger than Earth's and roughly 28.3 times Jupiter's mass.
