 In 2013, an international study modeled a lightcurve with a concurring period of 8.24991 hours and found a spin axis of (n.a., −99.0°) in ecliptic coordinates (λ, β).According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Lilofee" measures between 27.29 and 36 kilometers in diameter and its surface has an albedo between 0.07 and 0.198.The "Collaborative Asteroid Lightcurve Link" adopts an albedo of 0.08 and calculates a diameter of 34.04 kilometers based on an absolute magnitude of 10.7.
