According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Zamenhof" measures between 25.91 and 27.645 kilometers in diameter and its surface has an albedo between 0.087 and 0.121. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0891 and a diameter of 25.62 kilometers based on an absolute magnitude of 11.2. This minor planet was named after L. L.
