Disk-resolved photometry of Asteroid (2867) Steins

► We present a photometric analysis of the surface of the Asteroid (2867) Steins. ► We find that the surface exhibits a coherent-backscatter opposition effect (CBOE). ► The single scattering albedo is the highest (SSA = 0.55) ever observed among small bodies visited by spacecrafts. ► This high albedo is consistent with an iron-poor surface composition similar to aubrite meteorites. ► We find no photometric variations on the surface.
