HD 151450 and Its Two Known Planets

HD 151450 is a star 142 light-years from Earth with two known planets. Both planets were discovered in 2022 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The star itself has 1.14 solar masses, 1.17 solar radii, and a temperature of 6090 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

HD 151450 b has a minimum mass of 38.5 Earth masses and an orbital period of 21.9 days. A minimum mass is a lower bound on a planet's true mass, so this value represents the least it could weigh. This minimum mass is larger than Earth's, and among the listed planets, HD 151450 b has the shortest year by reported estimates.

HD 151450 c has a reported mass estimate of 1640 Earth masses, roughly 5.15 times Jupiter's mass, and an orbital period of 18100 days. Its reported mass estimate is larger than Earth's, and among the listed planets, it has the longest year by reported estimates.
