Notes	An orange giant is a variable star of the eruptive class. It lies in the extreme east of Corona Borealis in the sky, close to the Keystone of Hercules, and forms an optical double with the more distant red star Nu¹ Coronae Borealis.

Nu² Coronae Borealis forms an optical pair with Nu¹ Coronae Borealis, just five arcminutes to the north. Though marginally the brighter of the two as seen from Earth, Nu¹ Coronae Borealis is actually the more distant of the pair. Both stars are giants, but red Nu¹ is rather more luminous than orange Nu². Imagery provided by Aladin sky atlas
