HD 12235 and Its Two Planets

HD 12235 is a star 104 light-years away with two planets orbiting it. The host star has 1.1 solar masses, 1.8 solar radii, and a temperature of 5990 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

HD 12235 b was discovered in 2022 by the radial velocity method. It has a minimum mass of 10.5 Earth masses, larger than Earth's, and an orbital period of 4.36 days, the shortest year among the listed planets by reported estimates.

HD 12235 c was also discovered in 2022 by the radial velocity method. Its reported mass estimate is 3140 Earth masses, larger than Earth's and roughly 9.87 times Jupiter's mass. Its orbital period of 36300 days is the longest year among the listed planets by reported estimates.
