of NASA's Wide-field Infrared Survey Explorer (WISE), and the Japanese Akari satellite, Melanie measures (), () and () kilometers in diameter and its surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link adopts the albedo obtained by IRAS and derives a diameter of 41.38 kilometers using an absolute magnitude of 10.59. Alternative mean-diameters published by the WISE team include (), (), (), () and () with a corresponding albedo of (), (), (), () and (). On 4 August 2002, an asteroid occultation gave a best-fit ellipse dimension of () with a low quality rating of 0. These timed observations are taken when the asteroid passes in front of a distant star.
