[11] With μ Virginis it forms one of the Akkadian lunar mansions Mulu-izi[12](meaning "Man-of-fire"[13]).

δ Librae is approximately 300 light years from the Earth and the primary, component A, belongs to the spectral class B9.5V, indicating it is a B-type main-sequence star.

It is visible to the naked eye with an apparent visual magnitude of 4.93[3] and is moving closer to the Sun with a radial velocity of −39 km/s.

[14] The secondary is filling its Roche lobe and there is evidence of large-scale mass transfer in the past, with the star being more evolved than the primary.

[9] Along with λ Tauri, it was one of the first stars on which rotational line broadening[15] was observed, by Frank Schlesinger in 1911.
