HD 173416 and Its Lone Planet

HD 173416 is a G8 star 431 light-years away. Its mass is 2 solar masses and its radius is 13.5 solar radii, both larger than the Sun's, and its temperature of 4680 K is cooler than the Sun's. One planet orbits this host.

That planet, HD 173416 b, was discovered in 2008 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. Its minimum mass, a lower bound on its true mass, is 585 Earth masses, roughly 1.84 times Jupiter's mass. It completes one orbit every 322 days.
