HD 211810 b: A Giant Planet Orbiting a Sun-Like Star

HD 211810 is a G-type star 211 light-years from Earth. It is a single-star system, and one known planet orbits it. The star is slightly more massive than the Sun at 1.03 solar masses and slightly larger at 1.13 solar radii, with a temperature of 5650 K, which is cooler than the Sun's.

The planet HD 211810 b was discovered in 2018 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 211810 b has a minimum mass of 213 Earth masses, a lower bound on its true mass, and it completes one orbit every 1560 days. Its minimum mass is larger than Earth's.
