Lambda Lupi

It is visible to the naked eye with a combined apparent visual magnitude of 4.04.

[2] Based upon an annual parallax shift of just 4.20[1] mas as seen from Earth, it is located roughly 800 light years from the Sun.

[9] It is a member of the Upper Centaurus–Lupus sub-group in the Scorpius–Centaurus OB association.

[12] The two visible components of this system orbit each other over a period of 70.8 years with a large eccentricity of 0.63.

[3] Both are B-type main sequence stars with a stellar classification of B3 V.[5] One of the pair is itself a double-lined spectroscopic binary, making this a triple star system.
