HD 30856 and Its Lone Known Planet

HD 30856 is a K0 III star 428 light-years away, with a recorded age of 3.89 billion years. Its mass is 1.31 solar masses, so the star's reported mass estimate is larger than the Sun's, and its radius of 4.15 solar radii also exceeds the Sun's. At 4940 K, the star's reported temperature is cooler than the Sun's. One known planet orbits this host.

That planet, HD 30856 b, was found in 2011 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 492 Earth masses, meaning this value is a lower bound on the planet's true mass, and it is also larger than Earth's and roughly 1.55 times Jupiter's mass. The planet completes one orbit every 847 days.
