We derive the global photometric properties of Itokawa in terms of Hapke's photometric model. We find that Itokawa has a single-scatter albedo that is 35–40% less than that of Asteroid 433 Eros. Itokawa also has a single-particle phase function that is more strongly back-scattering than that of Eros. Despite its hummocky surface strewn with large boulders, Itokawa exhibits an opposition effect. However, the total amplitude of the opposition surge for Itokawa was estimated to be less than unity while Eros and other S-type asteroids have been found to have model values exceeding unity. The wavelength dependence of the opposition surge width reveals that coherent backscatter contributes to the opposition effect on Itokawa's surface. The photometric roughness of Itokawa is well constrained to a value of 26° ± 1° which is similar to Eros, suggesting that photometric roughness models the smallest surface roughness scale for which shadows exist."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320400193925","@type":"Researcher","foaf:name":[{"@value":"Kohei Kitazato"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320400193794","@type":"Researcher","foaf:name":[{"@value":"Beth E.
