 Modeled photometric data from the Lowell Photometric Database (LPD) and the robotic BlueEye600 Observatory, gave a concurring period of 5.57556 and 5.57557 hours, respectively.Both studies determined two spin axes of (72.0°, −66.0°) and (241.0°, −66.0°), as well as (61.0°, −2.0°) and (223.0°, −68.0°) in ecliptic coordinates (λ, β).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, "Britta" measures between 9.860 and 11.76 kilometers in diameter and its surface has an albedo between 0.223 and 0.346.
