HD 48265 and Its Two Known Planets
HD 48265 is a G-type star 295 light-years away, and two planets have been reported around it. The star is classified as G5 IV/V, with an age of 5 billion years, a mass of 1.28 solar masses, and a radius of 2.05 solar radii. Its temperature is 5650 K. Its reported mass and radius are larger than the Sun's, while its reported temperature is cooler.
HD 48265 b was discovered in 2008 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 485 Earth masses, a lower bound on its true mass, and it is roughly 1.53 times Jupiter's mass. It completes an orbit in 779 days, the shortest year among the listed planets.
HD 48265 c was also found by radial velocity, with a discovery year of 2026. Its reported mass is 1410 Earth masses, roughly 4.45 times Jupiter's mass, and it orbits in 10400 days, the longest year among the listed planets.
