243 Ida is a large asteroid shaped very elongated, perhaps a contact binary. It was discovered by Johann Palisa on 29 September 1884 and was named for a nurse of Zeus. On 17 February 1994, Ida was discovered to boast a small moon (Dactyl) as it was imaged during the flyby of the Gallileo spacecraft in 1993 as it flew by enroute to Jupiter.
