 The modelling also gave two poles at (343.0°, −74.0°) and (133.0°, −75.0°) in ecliptic coordinates (λ, β).According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer and the Japanese Akari satellite, "Lalage" measures () and () kilometers in diameter and its surface has an albedo of () and (), respectively.The "Collaborative Asteroid Lightcurve Link" assumes an albedo of 0.20 and a diameter of 10.16 kilometers based on an absolute magnitude of 12.33.
