HD 88986 and Its Super-Earth

HD 88986 is a Sun-like, G-type main-sequence star 109 light-years away, with a mass of 1.25 solar masses and a radius of 1.54 solar radii. Its temperature is 5860 K, making it hotter than the Sun, and its age is 7.9 billion years. One planet orbits this host.

That planet, HD 88986 b, is a Super-Earth discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. It has a mass of 17.2 Earth masses, a radius of 2.49 Earth radii, and an orbital period of 146 days. Its mean density is 6.14 g/cm³, 1.11 times Earth's.
