Eos family

(ee -os) A Hirayama family of asteroids located at a distance of 3.0 AU from the Sun. The members are unusual and their color lies between that of C-type and S-type asteroids. Their reflection spectra are very similar to chondrite meteorites. Observations of spin rates indicate that the family is old.
