HD 80869 and Its Giant Planet

HD 80869 is a G1 V star located 279 light-years away, with a reported mass of 1.08 solar masses and a radius of 1.06 solar radii. Its temperature is 5840 K. One planet orbits this star.

That planet, HD 80869 b, was discovered in 2021 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a mass of 1610 Earth masses and an orbital period of 1750 days.

The star's reported mass estimate is larger than the Sun's, as is its reported radius estimate, and its reported temperature is hotter than the Sun's. HD 80869 b's mass estimate is larger than Earth's and roughly 5.07 times Jupiter's mass.
