HD 22532 b: A Giant Planet Orbiting a Distant Star

HD 22532 is a star located 526 light-years away. Its spectral type is G8 III/IV. The star has a mass of 1.57 solar masses, a radius of 5.69 solar radii, and a temperature of 5040 K. One planet is known to orbit this host.

That planet is HD 22532 b, discovered in 2022 by the radial velocity method. This method measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 22532 b has a minimum mass of 674 Earth masses, a lower bound on the planet's true mass that differs from an ordinary mass estimate. Its minimum mass is larger than Earth's and roughly 2.12 times Jupiter's mass. The planet completes one orbit every 873 days.

The star's reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's.
