Hvězda 66 Oph se skládá z dvojhvězdy s periodou 10.74 dne, která obíhá hlavní složku typu Be. Parametry dvojhvězdy byly odvozeny dvěma nezávislými metodami a spektra jednotlivých složek separována užitím metody tzv. Fourierovského rozmotání (Fourier disentangling). (cs)
66 Oph is a multiple system with a close binary orbiting the B2Ve primary Be star. The binary parameters were derived by two independent methods and spectra of components BA and BB were separated by Fourier-disentangling.
