HD 80606 and Its Giant Planet
HD 80606 is a G5 star 217 light-years away with a mass of 1.02 solar masses, a radius of 1.04 solar radii, a temperature of 5570 K, and an age of 5.9 billion years. Its reported radius is larger than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
HD 80606 b is a Jupiter-like planet discovered in 2001 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. It has a mass of 1320 Earth masses, a radius of 11.6 Earth radii, and an orbital period of 111 days. Its reported radius is larger than Earth's, and its reported mass is larger than Earth's, roughly 4.16 times Jupiter's mass. Its mean density is 4.71 g/cm³, 0.855 times Earth's.
