ARICNS =Tau1 Arietis (τ1 Ari / τ1 Arietis) is a
triple star system in theconstellation Aries. It is approximately 462light year s fromEarth .The primary component, τ¹ Arietis A, is an
eclipsing binary which is classified as a blue-white B-typesubgiant . The two components haveapparent magnitude s of +5.4 and +7.9 and are separated by 0.15arcsecond s. At 0.67 arcseconds from A is τ¹ Arietis B, which has an apparent magnitude of +8.4. The combined mean apparent magnitude of the system is +5.27, but due to eclipsing of the binary components, the brightness varies from magnitude +5.26 to +5.32.External links
