HD 109286 and Its Planet

HD 109286 is a G4 V star, a Sun-like dwarf, located 181 light-years away. Its mass is 0.98 solar masses, its radius is 1.09 solar radii, and its temperature is 5690 K. The star's reported radius estimate is larger than the Sun's, while its reported temperature is cooler than the Sun's. One planet orbits this host.

That planet is HD 109286 b, discovered in 2021 by the radial velocity method. Its minimum mass is 950 Earth masses, which is larger than Earth's and roughly 2.99 times Jupiter's mass. Its orbital period is 520 days.
