HD 51608 and Its Two Known Planets
HD 51608 is a K-type star 114 light-years away, with a spectral type of K0 IV-V. It has a mass of 0.93 solar masses, a radius of 0.917 solar radii, and a temperature of 5350 K. The star's reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. Two planets are known to orbit this host.
HD 51608 b was discovered in 2019 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 12.8 Earth masses, larger than Earth's, and an orbital period of 14.1 days. Among the listed planets, HD 51608 b has the shortest year and the smallest minimum mass. HD 51608 c was also discovered in 2019 by radial velocity. It has a minimum mass of 14.3 Earth masses, larger than Earth's, and an orbital period of 95.9 days. Among the listed planets, HD 51608 c has the longest year and the largest minimum mass.
