BD+48 738 and Its Planet

BD+48 738 is a K-type giant star 2840 light-years away. It has 0.74 solar masses and 11 solar radii, and its temperature is 4410 K. Its radius is larger than the Sun's, and it is cooler than the Sun. One planet orbits this star: BD+48 738 b.

BD+48 738 b was discovered in 2011 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. Repeated wobbles reveal the planet and its orbital period. The planet's minimum mass, a lower bound on its true mass, is 289 Earth masses, larger than Earth's. Its orbital period is 393 days.
