HD 109988 and Its Planet

HD 109988 is a star 139 light-years from Earth with one known planet. The star's reported mass estimate is smaller than the Sun's, at 0.88 solar masses, and its reported radius estimate is smaller than the Sun's, at 0.87 solar radii. Its reported temperature is cooler than the Sun's, at 5190 K.

The planet HD 109988 b was discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet's mass is 6940 Earth masses, larger than Earth's and roughly 21.8 times Jupiter's mass. Its orbital period is 17100 days.
