HD 120084 and Its Giant Planet
HD 120084 is a G7 III star 336 light-years from Earth. It is 1.02 billion years old, holds 2.12 solar masses and spans 9.13 solar radii, and its temperature is 4890 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler. One planet orbits this host.
That planet, HD 120084 b, was found in 2013 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. It has a mass of 2030 Earth masses, a figure larger than Earth's and roughly 6.4 times Jupiter's mass, and it completes an orbit every 2140 days.
