Abstract

Analysis of the disk-integrated solar phase curve of 433 Eros, as derived from ground-based telescopic and NEAR Shoemaker spacecraft measurements, shows that Eros's surface properties are typical of average S-type asteroids. Eros displays the same single-particle scattering characteristics and porosity vs theoretical grain size relationships as typical S-asteroids, as does Ida. Eros's single-scattering albedo, however, is higher. The geometric albedo at 550 nm derived for Eros (0.29 ± 0.02) is higher than Ida's but is equivalent to Gaspra's within the error bars. The phase integral (0.39 ± 0.02) and Bond albedo (0.12 ± 0.02) for Eros are higher than those estimated for average S-type asteroids but commensurate with the values obtained for Gaspra.
