 Lightcurve analysis gave a rotation period of hours with a brightness variation of magnitude ().This result supersedes a period determination of 16+ hours by Pierre Antonini from June 2006 (), and of hours with an amplitude of magnitude by John Menke at the Menke Observatory in January 2004 ().According to the survey 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, "Whittemora" measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively.
