BD+55 362: A Cool Star and Its Giant Planet

BD+55 362 is a K3 star located 171 light-years away, with a mass of 0.909 solar masses and a temperature of 5010 K. Its reported temperature is cooler than the Sun's. One planet orbits this host.

That planet, BD+55 362 b, was discovered in 2021 using the radial velocity method. The radial velocity method measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. BD+55 362 b has a minimum mass of 229 Earth masses and an orbital period of 266 days. A minimum mass is a lower bound on a planet's true mass, and this minimum mass is larger than Earth's.
