HD 156098 and Its Two Known Planets

HD 156098 is a star 157 light-years from Earth with two planets in its system. The star has a mass of 1.29 solar masses, a radius of 2.76 solar radii, and a temperature of 6420 K, making it more massive, larger, and hotter than the Sun.

HD 156098 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 minimum mass of 15.9 Earth masses and an orbital period of 21.9 days, the shortest year among the listed planets.

HD 156098 c was also discovered in 2022 by radial velocity. It has a mass of 1660 Earth masses, roughly 5.23 times Jupiter's mass, and an orbital period of 7840 days, the longest year among the listed planets.
