HD 217958: A Distant Star With One Known Planet

HD 217958 is a star 202 light-years from Earth. Its mass is 1.08 solar masses, its radius is 1.33 solar radii, and its temperature is 5930 K. The star's reported radius estimate is larger than the Sun's. One planet has been found orbiting this host.

That planet is HD 217958 b, discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 217958 b's reported mass estimate is 167 Earth masses, larger than Earth's, and its orbital period is 2560 days.
