A substantial body of indirect evidence suggests that some asteroids have satellites, although none has been detected unambiguously. Collisions between asteroids provide physically plausible mechanisms for the production of binaries, but these operate with low probability; only a small minority of asteroids are likely to have satellites.

Formation of satellites around large asteroids
Known satellites orbiting asteroids larger than ~100 km are found preferentially around primary bodies with rotation periods 5-6 h. This is significantly more rapid rotation than is typical for asteroids this large, which have an average rotation period closer to 10 hours.Kevin Walsh +5 more

Prediction of stellar occultations by satellite of asteroids
2004Our group is working on the orbit determination of asteroid satellites on the last four years gathering data recorded with several AO systems. Based upon our observations, we focused specifically on models for (22) Kalliope, (121) Hermione, (45) Eugenia and (90) Antiope systems characterizing accurately their dynamical and physical properties (Marchis ...
