Planets Around HIP 8541
HIP 8541 is a K2 III/IV star 506 light-years away with two planets in its catalog. The star is 11 billion years old and has a mass of 0.96 solar masses, a radius of 6.84 solar radii, and a temperature of 4670 K.
HIP 8541 b was discovered in 2016 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. It has a mass of 2450 Earth masses, roughly 7.71 times Jupiter's mass, and a period of 1850 days, the longest among the listed planets.
HD 11343 c was discovered in 2022 by the same radial velocity method. Its minimum mass, a lower bound on its true mass, is 256 Earth masses, and it takes 229 days to complete an orbit, the shortest year among the listed planets.
