BD+37 3172 b: A Giant Planet Orbiting a Giant Star

BD+37 3172 is a star located 1480 light-years away. It is a single-star system with one known planet. The star is substantially larger than the Sun: its mass is 3.75 solar masses, its radius is 50.2 solar radii, and its surface temperature is 4500 K. Both its mass and radius are larger than the Sun's, while its temperature is cooler.

The one known planet is BD+37 3172 b, discovered in 2023 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 3370 Earth masses, roughly 10.6 times Jupiter's mass and larger than Earth's mass. Its orbital period is 1890 days, the time it takes to complete one orbit around its host.
