HD 24040 and Its Two Known Planets
HD 24040 is a G-type dwarf star 152 light-years away. Its mass is 1.03 solar masses, its radius is 1.38 solar radii, and its temperature is 5760 K. The star's reported radius estimate is larger than the Sun's. Two planets are known to orbit it.
HD 24040 b was discovered in 2006 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 1230 Earth masses, which is roughly 3.86 times Jupiter's mass, and its orbital period is 3670 days. Among the listed planets, it has the longest year and the largest minimum mass.
HD 24040 c was discovered in 2021 by the radial velocity method. It has a minimum mass of 63.9 Earth masses and an orbital period of 515 days. Among the listed planets, it has the shortest year and the smallest minimum mass.
