BD+48 740 and Its Planet

BD+48 740 is a K3 III star 2170 light-years away, with a reported mass of 1.09 solar masses, radius of 10.3 solar radii, and temperature of 4530 K. Its radius estimate is larger than the Sun's, while its temperature is cooler than the Sun's.

One planet orbits this host. BD+48 740 b was discovered in 2018 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet has a minimum mass of 540 Earth masses and an orbital period of 733 days. Its minimum mass is larger than Earth's and roughly 1.7 times Jupiter's mass.
