Kappa Coronae Borealis is a star approximately 102 light years away in the constellation of Corona Borealis.The apparent magnitude is +4.82 (4.17 trillion times fainter than the Sun) and the absolute magnitude is +2.35 (9.82 times brighter than the Sun). It is an orange K-type subgiant star, meaning it has nearly completely exhausted its hydrogen supply in its core.
