HD 331093 b: A Planet Orbiting a Cool Star

HD 331093 is a K0 star located 164 light-years from Earth, with a mass of 1.03 solar masses and a temperature of 5540 K. That temperature is cooler than the Sun's. One planet orbits this star.

HD 331093 b was discovered in 2021 using the radial velocity method, which detects the gravitational wobble a planet induces in its star's motion. The planet has a minimum mass of 477 Earth masses, a lower bound on its true mass, and completes one orbit every 622 days.

That minimum mass is larger than Earth's and roughly 1.5 times Jupiter's mass.
