HD 105618 and Its Two Known Planets

HD 105618 is a star located 229 light-years away. It has 1.01 solar masses, a radius of 1.27 solar radii, and a temperature of 5670 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is cooler than the Sun's. Two planets are known to orbit this host.

HD 105618 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 25.4 Earth masses and an orbital period of 10 days, the shortest year among the listed planets by reported estimates. Its minimum mass is larger than Earth's.

HD 105618 c was also discovered in 2022 by radial velocity. Its reported mass estimate is 8420 Earth masses, roughly 26.5 times Jupiter's mass, and larger than Earth's. Its orbital period is 77100 days, the longest year among the listed planets by reported estimates.
