HD 125271 and Its Planet

HD 125271 is a star 128 light-years from Earth with one known planet. The host star has a mass of 0.75 solar masses, a radius of 0.751 solar radii, and a temperature of 4700 K. Its reported mass estimate is smaller than the Sun's, as is its radius, and it is cooler than the Sun.

The planet HD 125271 b was discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. It has a mass of 3470 Earth masses - roughly 10.9 times Jupiter's mass, and larger than Earth's - and an orbital period of 14900 days.
