HD 29985 and Its Distant Planet

HD 29985 is a star 102 light-years from Earth, with a reported mass of 0.75 solar masses, a radius of 0.575 solar radii, and a temperature of 4680 K. Each of these estimates is smaller or cooler than the Sun's corresponding value. One planet is known to orbit this host.

That planet, HD 29985 b, was discovered in 2022 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a mass of 1740 Earth masses, roughly 5.47 times Jupiter's mass and larger than Earth's mass. Its orbital period is 20600 days.
