This system is approximately 180 light years〔 from Earth and has a combined apparent magnitude of +3.78.〔 The individual magnitudes differ slightly, with component A having a magnitude of 4.43〔 and component B at the slightly dimmer magnitude 4.83.〔 The binary nature of this system has been tracked since 1796. They complete an orbit roughly every 45,460 days, or 124.46 years. The next close approach will occur during August 2023. The orbit of this pair has a very high eccentricity of 0.9977, bringing the stars within 0.3 AU at their closest approach.〔 Image:zboo lucky image 1pc.png|Zeta Bootis imaged with the Nordic Optical Telescope on 13 May 2000 using the lucky imaging method.
