HD 156846 and Its Planet

HD 156846 is a G-type main-sequence star 156 light-years away, with a single known planet in orbit. The star is estimated to be 2.78 billion years old, with a mass of 1.38 solar masses and a radius of 1.95 solar radii. Its temperature is 6080 K, and its reported mass, radius, and temperature are all larger or hotter than the Sun's.

The one planet circling this star is HD 156846 b, discovered in 2007 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet has a minimum mass of 3390 Earth masses - a lower bound on its true mass - roughly 10.7 times Jupiter's mass, and an orbital period of 360 days.
