Dactyl, discovered in 1993, is a tiny asteroid (diameter 1.4 km) that orbits asteroid 243 Ida with a period of 1.54 days at an average distance of 108 km. The origins of Dactyl are unclear. The two main theories are that it and Ida formed at the same time, and that it was knocked loose by a later impact. Both theories have problems and cannot explain the situation satisfactorily.

Dactyl, found by the Galileo probe, was the first asteroid moon discovered.
