HD 222076 and Its Planet
HD 222076 is a K1 III star 297 light-years away. It is 4.5 billion years old, with a mass of 1.28 solar masses and a radius of 4.28 solar radii. Its temperature is 4880 K, making it cooler than the Sun, while its mass and radius are both larger than the Sun's. One planet orbits this star.
HD 222076 b was discovered in 2016 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 496 Earth masses, roughly 1.56 times Jupiter's mass and larger than Earth's, and its orbital period is 871 days.
