text: According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Ikeller measures 5.4 kilometers in diameter and its surface has an albedo of 0.22, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for Koronian asteroids of 0.24 and thus calculates a smaller diameter of 5.2 kilometers, as the higher the albedo (reflectivity), the smaller a body's diameter at a certain absolute magnitude (brightness).
