Kappa Coronae Borealis b is an extrasolar planet approximately 98 light-years away[1] in the constellation of Corona Borealis. This planet was discovered by Johnson et al., who used the radial velocity method to detect wobbling of the star caused by a planet move around by its tug of gravity. It was first discovered in September 2007 and was published in November.[2]
The planet is 1.8 Jupiter masses, or 570 Earth masses, although only the minimum mass is known since the inclination is not known. It orbits at a distance of 2.7 astronomical units, or 400 gigameters, and takes 1,208 days, or 3.307 years, to orbit around Kappa Coronae Borealis.
