 The study also determined two spin axes of (201.0°, −41.0°) and (2.0°, −36.0°) in ecliptic coordinates (λ, β).According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), and the Japanese Akari satellite, "Rotraut" measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively.The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0506 and a diameter of 56.42 kilometers based on an absolute magnitude of 10.1.
