HD 112300 b: A Giant Minimum-Mass Planet Orbiting a Cool Giant Star

HD 112300 is a star located 202 light-years away, and it hosts one known planet. The star has a spectral type of M1 III, with a mass of 1.4 solar masses and a radius of 65.8 solar radii. Its temperature is 3660 K, and its mass, radius, and temperature compare to the Sun as larger, larger, and cooler, respectively.

The planet HD 112300 b was discovered in 2023 using the radial velocity method, which detects the wobble a planet's gravity induces in its star. Its minimum mass - a lower bound on its true mass - is 5030 Earth masses, roughly 15.8 times Jupiter's mass and larger than Earth's. The planet takes 467 days to complete one orbit.
