HD 111232: A Sun-Like Star With Two Giant Planets
HD 111232 is a G5 V star, a Sun-like main-sequence dwarf, located 94.4 light-years away. Its reported mass is 0.7 solar masses, smaller than the Sun's, and its reported temperature is 5410 K, cooler than the Sun's. The star's radius is 0.95 solar radii, and its age is a reported lower limit of 13 billion years. Two planets are known to orbit this host.
HD 111232 b was discovered in 2003 by the radial velocity method. It has a mass of 2530 Earth masses, roughly 7.97 times Jupiter's mass and larger than Earth's. Its orbital period is 1170 days.
HD 111232 c was discovered in 2022, also by radial velocity. Its mass is 5740 Earth masses, roughly 18.1 times Jupiter's mass and larger than Earth's, and its orbital period is 26500 days.
Among the listed planets, HD 111232 b has the shortest year by reported estimates, at 1170 days, and the smallest reported mass, at 2530 Earth masses. HD 111232 c has the longest year, at 26500 days, and the largest reported mass, at 5740 Earth masses.
