Gamma Lupi

The system has a hierarchical architecture. The primary, Gamma Lupi A is itself a spectroscopic binary with an orbital period of 2.849769 days. Although the system does not show eclipses, the hotter star of the pair heats the side of the cooler star that faces it, and as they orbit each other the combined starlight varies in brightness by about 0.02 magnitudes, as seen from the Earth. The outer component, Gamma Lupi B, is widely-separated, with a semi-major axis of 81 astronomical units and an orbital period of 210 years.

This star is a proper motion member of the Upper Centaurus–Lupus sub-group in the Scorpius–Centaurus OB association, the nearest such co-moving association of massive stars to the Sun.
