 In the Tholen classification, "Lalage" has an unusual spectrum, that is closest to a dark D-type, somewhat similar to an X-type, and, to a lesser extent, a carbonaceous C-type asteroid.Conversely, the Small Solar System Objects Spectroscopic Survey (S3OS2), classifies the body an uncommon A-type in the survey's Tholen-like taxonomic variant, and as an Sl-subtype – which transitions from the stony S-type to the uncommon L-type asteroid – in its SMASS-like variant.In September 1992, a rotational lightcurve of "Lalage" was obtained from photometric observations by Polish astronomer Wiesław Wiśniewski.
