HD 168863 and Its Lone Known Planet

HD 168863 is a star 130 light-years from Earth. It has 0.8 solar masses and a radius of 0.778 solar radii, and its temperature is 4910 K, making it less massive, smaller, and cooler than the Sun. One known planet orbits this host.

That planet, HD 168863 b, was discovered in 2022 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. It has a mass of 2150 Earth masses and an orbital period of 14800 days, the time it takes to complete one orbit. That mass is larger than Earth's and roughly 6.78 times Jupiter's mass.
