HIP 97233: A Cool Giant Star and Its One Known Planet
HIP 97233 is a K0 star 334 light-years away, and one planet has been found in its orbit. A spectral type beginning with K indicates a star cooler than the Sun, and the star's measured temperature of 5020 K is indeed cooler than the Sun's. Its mass is 1.93 solar masses, larger than the Sun's, and its radius is 5.34 solar radii, also larger than the Sun's.
The single known planet is HIP 97233 b, discovered in 2014 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's mass is 6100 Earth masses, larger than Earth's and roughly 19.2 times Jupiter's mass, and it completes an orbit in 1060 days.
