HD 156279 and Its Two Planets

HD 156279 is a G6 star 118 light-years away with two planets. Its mass is 0.93 solar masses, its temperature is 5450 K, and its age is 4.1 billion years.

HD 156279 b was found by radial velocity in 2011, and HD 156279 c was found the same way in 2016. Both are giant planets: b has a minimum mass of 3000 Earth masses, while c has a mass of 3100 Earth masses. Their years differ greatly - b takes 133 days and c takes 4820 days.

Among the listed planets, HD 156279 b has the shortest year by reported estimates, at 133 days. HD 156279 c has the longest year by reported estimates, at 4820 days. The star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
