 The body's high brightness amplitude of 0.78 magnitude also indicates that it has a non-spheroidal shape.According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Geake" measures between 11.54 and 14.040 kilometers in diameter and its surface has a low albedo between 0.033 and 0.05.Contrary to the results obtained by the space-based observatories, the "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20, derived from the family's namesake, and consequently calculates a much shorter diameter of 6.50 kilometers based on an absolute magnitude of 13.3, as the higher a body's reflectivity the smaller its diameter for a given brightness.
