BD+42 2315 b: A Giant Planet Orbiting a Distant Star

BD+42 2315 is a star located 1990 light-years away. It has a mass of 1.38 solar masses and a radius of 17.9 solar radii, making it both more massive and larger than the Sun. Its temperature is 4500 K, cooler than the Sun. One known planet orbits this star.

The planet, BD+42 2315 b, was discovered in 2023 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Its minimum mass is 175 Earth masses, a lower bound on its true mass that is larger than Earth's. It completes one orbit every 123 days.
