(λ, β). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Hakone measures between 24.73 and 29.567 kilometers in diameter and its surface has an albedo between 0.1745 and 0.245. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1865 and a diameter of 24.44 kilometers based on an absolute magnitude of 10.5.
