Rotation period In October 1999, a rotational lightcurve of Kordula was obtained from photometric observations by Vincenzo Zappalà and his Italian colleagues. Lightcurve analysis gave a well-defined rotation period of hours with a brightness amplitude of magnitude (). Diameter and albedo According to the surveys 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, Kordula measures (), () and () kilometers in diameter, and its surface has an albedo of (), () and (), respectively. Further published mean-diameters and albedos by the WISE team include (), (), (), and () with corresponding albedos of (), (), (), and (). The Collaborative Asteroid Lightcurve Link adopts the results from IRAS, that is, an albedo of 0.0352 and a diameter of 87.21 km based on an absolute magnitude of 9.55.
