HD 60532 and Its Two Known Planets

HD 60532 is a star 84.7 light-years from Earth with two planets orbiting it. Its spectral type is F6V, which classifies it as an F-type main-sequence star, hotter and more massive than the Sun. The star's reported mass estimate is 1.5 solar masses, larger than the Sun's, and its reported radius estimate is 2.5 solar radii, also larger than the Sun's. Its reported temperature is 6250 K, hotter than the Sun's, and its age is 2.25 billion years.

Both planets were discovered in 2008 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. HD 60532 b has a minimum mass of 337 Earth masses, a lower bound on its true mass, and an orbital period of 202 days, the shortest year among the listed planets. Its minimum mass is larger than Earth's. HD 60532 c has a minimum mass of 798 Earth masses, also a lower bound, and an orbital period of 600 days, the longest year among the listed planets. Its minimum mass is larger than Earth's and roughly 2.51 times Jupiter's mass.
