It is faintly visible to the naked eye with an apparent visual magnitude of 5.37.[2] Based upon an annual parallax shift of 8.02[1]\u00a0mas as seen from Earth, it is located around 410\u00a0light years from the Sun. The two components of Upsilon Lupi share a common proper motion through space and most likely form a wide binary star system.[10] As of 1945, the pair had an angular separation of 1.50\u00a0arc seconds along a position angle of 40\u00b0.[3]The brighter member, component A, is a chemically peculiar Ap star with a stellar classification of A0p\u00a0Si,[4] where the ‘Si’ suffix indicates an abnormal abundance of silicon in the star’s photosphere. A magnetic field has been detected with a quadratic field strength of (764.7\u00b1311.3)\u00d710\u22124\u00a0T.[11] The star is radiating 113 times the solar luminosity from its outer atmosphere at an effective temperature of 10,049\u00a0K.[7]The magnitude 10.9 companion star, component B, has a visual magnitude of 10.90.[3] It may be the source of the X-ray emission detected coming from these coordinates.[12]References[edit]^ a b c d e f van Leeuwen, F.
