Zeta Coronae Borealis designated B. The brighter star is also known as ζ Coronae Borealis and the fainter as ζ Coronae Borealis. Each of the pair has its own Bright Star Catalogue and Henry Draper Catalogue numbers: HR 5833 and 5834, and HD 139891 and 139892 for ζ and ζ respectively. ζ Coronae Borealis is a single-lined spectroscopic binary, with an orbital period of about 9.5 days. The nature of the companion is unknown. The brighter star, ζ Coronae Borealis, is a spectroscopic triple system, consisting of three massive stars. The inner pair orbit in 1.7 days, while the outer pair orbit in
