HD 4760 and Its Planet

HD 4760 is a K2 star 1750 light-years away with 1.05 solar masses, a radius of 42.4 solar radii, and a temperature of 4080 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this star.

HD 4760 b was discovered in 2021 by radial velocity, a method that 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 minimum mass is 4420 Earth masses, which is larger than Earth's and roughly 13.9 times Jupiter's mass. A minimum mass is a lower bound on a planet's true mass. HD 4760 b completes an orbit every 434 days.
