HD 112640 b: A Giant Planet Orbiting an Aging Star

HD 112640 is a K0 III star located 1050 light-years away. It has a mass of 1.8 solar masses and a radius of 39 solar radii, making it larger than the Sun in both respects. Its temperature is 4160 K, cooler than the Sun's. The star is 1.6 billion years old. One planet orbits this host.

HD 112640 b was discovered in 2020 using the radial velocity method. Repeated wobbles in the star's motion reveal the planet and its orbital period. This world has a minimum mass of 1590 Earth masses, roughly 5 times Jupiter's mass, and completes one orbit every 613 days.
