The combined apparent visual magnitude of the pair is 5.02, making the system bright enough for it to be dimly visible to the naked eye. Kappa Arietis is a double-lined spectroscopic binary with both components displaying the spectral properties of an Am, or metallic-lined star. They have nearly the same brightness and their mass ratio is 1.03; very close to equal. Their orbital period is 15.2938 days and they have a high eccentricity of 0.61.
