HD 111591 is a K0 star 372 light-years away. It is 1.41 billion years old, with a mass of 1.94 solar masses and a radius of 8.03 solar radii. Its temperature is 4880 K, cooler than the Sun's, while its reported mass and radius estimates are both larger than the Sun's.
One planet orbits this host. HD 111591 b was found in 2017 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet has a minimum mass of 1400 Earth masses, a lower bound on its true mass, and that minimum mass is larger than Earth's and roughly 4.4 times Jupiter's mass. Its orbital period is 1060 days.
