摘要: We identified the family of binary asteroid 423 Diotima consisting 411 members in phase space orbital elements—semimajor axes a (or mean motions n), eccentricities e, and inclinations i—by using an electronic version ephemerides minor planets EMP-2003 containing osculating elements for 34992 asteroids main belt. The 9/4 resonance with Jupiter clearly separates from Eos, which, according to EMP 2003, contains 1204 asteroids.
