HD 38801 and Its Planet
HD 38801 is a K0 star 298 light-years away. Its reported mass is 1.36 solar masses, greater than the Sun's, and its radius of 2.53 solar radii is also larger than the Sun's. At 5220 K, the star is cooler than the Sun, and it is 4.67 billion years old. One planet orbits this host.
That planet, HD 38801 b, was discovered in 2009 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 3080 Earth masses, a lower bound on its true mass and roughly 9.7 times Jupiter's mass. HD 38801 b completes one orbit every 685 days.
