According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Mombasa" measures between 52.46 and 62.45 kilometers in diameter, ignoring a preliminary result of 127 km, and its surface has an albedo of 0.025 and 0.06. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0415 and a diameter of 56.83 kilometers with an absolute magnitude of 10.3.
