Gamma Coronae Borealis (γ CrB) is a star in the constellation Corona Borealis. Its apparent magnitude is 3.84. A binary star system, its components orbit each other every 92.94 years and are roughly as far apart from each other as the Sun and Neptune.[2] The individual stars have visual magnitudes of 4.04 and 5.60,[3] and spectral types B9V and A3V.[4]
