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, Naëma measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0503 and a diameter of 54.05 kilometers based on an absolute magnitude of 10.2. Alternative mean-diameter measurements published by the WISE team include (), (), (), () and () with corresponding albedos of (), (), (), () and (). Several asteroid occultations of Naëma have been observed between 2002 and 2010. The best-rated one from 10 April 2010, gave a best-fit ellipse dimension of (). These timed observations are taken when the asteroid passes in front of a distant star.
