HD 69123 b: A Planet Orbiting a Cool Giant Star

HD 69123 is a K1 III star located 245 light-years away. Its mass is 1.68 solar masses, and its radius is 7.72 solar radii; both values are larger than the Sun's. With a temperature of 4840 K, the star is cooler than the Sun. One planet orbits this star.

The planet, HD 69123 b, was discovered in 2022 using the radial velocity method, which detects the gravitational wobble a planet induces in its star's motion. Its minimum mass is 966 Earth masses, roughly 3.04 times Jupiter's mass. This minimum mass is a lower bound on the planet's true mass. HD 69123 b completes one orbit around its star every 1190 days.
