HD 188641 and Its Planet

HD 188641 is a star 210 light-years away with a mass of 1.07 solar masses, a radius of 1.94 solar radii, and a temperature of 5900 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. The star hosts one known planet.

HD 188641 b was 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. The planet's mass of 9330 Earth masses is larger than Earth's and roughly 29.4 times Jupiter's mass.

HD 188641 b takes 14600 days to complete one orbit.
