Photometric studies of asteroids have been carried out by using ground-based telescopes. Recently, spacecraft observations have brought us more detailed photometric data, that is disk-resolved bidirectional reflectance data, of S-type asteroids (Gaspra, Ida, Eros). The target of MUSES-C, 1998SF36, is considered an S-type asteroid. The NEAR spacecraft found the surface composition of Eros is similar to that of ordinary chondrite meteorites. In this study, we measured the bidirectional reflectance of the ordinary chondrite meteorites with a He-Ne laser (wavelength 633nm) and photomultiplier. We will compare our data with S and Q-type asteroids' data, and discuss on a comparison between ordinary chondrites and S and Q-type asteroids in terms of the bidirectional reflectance.
