 Photometry by Angeli and Guimarães at observatories in Brazil and Argentina gave a similar period of hours ().In 2013, an international study modeled a lightcurve with a sidereal period of 8.82653 hours and found two spin axes at (47.0°, 57.0°) and (234.0°, 50.0°) in ecliptic coordinates (λ, β) ().According to the survey carried out by the Japanese Akari satellite, the Infrared Astronomical Satellite IRAS, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Kunigunde" measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively.
