HIP 75092 and Its Planet

HIP 75092 is a K-type giant star 266 light-years from Earth. It is 4.3 billion years old, with a mass of 1.28 solar masses and a radius of 4.53 solar radii. Its temperature is 4890 K, which is cooler than the Sun's, though its reported mass and radius estimates are both larger than the Sun's.

One planet is known to orbit this star. HIP 75092 b was discovered in 2021 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 569 Earth masses, a lower bound on its true mass, and completes an orbit every 926 days. That minimum mass is larger than Earth's and roughly 1.79 times Jupiter's mass.
