 Analysis of the classically shaped bimodal lightcurve gave a well-defined rotation period of hours with a brightness variation of magnitude ().During the same apparition, a virtually identical period of hours with an amplitude of magnitude () was determined by Kenda Albers and colleges of the Rose-Hulman Institute of Technology at the Oakley Southern Sky Observatory in Australia.According to the surveys carried out by the Infrared Astronomical Satellite IRAS, and the Japanese Akari satellite, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), "Henrika" measures (), () and () kilometers in diameter and its surface has a albedo of (), () and (), respectively.
