BD+45 564 b: A Distant World Orbiting a Cooler, Smaller Star

BD+45 564 is a K1-type star located 175 light-years from Earth. Its reported mass estimate is 0.85 solar masses, its reported radius estimate is 0.813 solar radii, and its reported temperature is 5090 K, all smaller or cooler than the Sun's corresponding values. One planet orbits this host.

That planet, BD+45 564 b, was discovered in 2021 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 432 Earth masses, a lower bound on its true mass, and is roughly 1.36 times Jupiter's mass. BD+45 564 b completes one orbit around its star every 308 days.
