omi CrB and Its Planet
omi CrB is a K0 III star 277 light-years away, with a mass of 1.3 solar masses, a radius of 11.9 solar radii, and a temperature of 4770 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet, omi CrB b, was discovered in 2012 by radial velocity, the method that measures the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 356 Earth masses and an orbital period of 187 days. Its minimum mass is larger than Earth's and roughly 1.12 times Jupiter's mass.
