HD 190984 and Its Planet
HD 190984 is an F8 V star 483 light-years away. Its reported radius is 1.53 solar radii, and its reported temperature is 5990 K. One planet orbits this host.
That planet is HD 190984 b, discovered in 2009 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is a lower bound on its true mass: 985 Earth masses, roughly 3.1 times Jupiter's mass, and larger than Earth's. Its orbital period is 4890 days. The star's reported mass is 0.91 solar masses.
