well as two spin axes at (69.0°, −62.0°) and (261.0°, −53.0°) in ecliptic coordinates (λ, β). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Schmidt measures between 17.00 and 20.78 kilometers in diameter and its surface has an albedo between 0.042 and 0.0603. The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0603 and a diameter of 17.28 kilometers based on an absolute magnitude of 12.48.
