 The study also determined two spin axes at (301.0°, 44.0°) and (154.0°, 69.0°) in ecliptic coordinates (λ, β).According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE) and the Japanese Akari satellite, "Adele" measures () and () kilometers in diameter and its surface has an albedo of () and (), respectively.The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for an Eunomian asteroid of 0.21 and calculates a diameter of 12.66 kilometers based on an absolute magnitude of 11.8.
