HD 102888: A Distant Star and Its One Known Planet

HD 102888 is a G8 III star located 413 light-years away. Its mass is 2.42 solar masses and its radius is 8.6 solar radii, both larger than the Sun's corresponding values. Its temperature is 4990 K, cooler than the Sun's. One planet has been found orbiting this star.

HD 102888 b was discovered in 2025 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 1810 Earth masses, roughly 5.69 times Jupiter's mass and larger than Earth's. Its orbital period is 252 days.
