 Lightcurve analysis gave a rotation period of hours with a low brightness variation of magnitude ().The result supersedes tentative period determinations by Pierre Antonini (2009), Stephane Fauvaud (2011) and René Roy (2014), which were of lower quality ().According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite IRAS, and the Japanese Akari satellite, "Rockefellia" measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively.
