Dactyl (/ˈdæktɪl/ DAK-til; formally (243) Ida I Dactyl) is a tiny asteroid moon (1 mile, or 1.6 km, in diameter) that orbits asteroid 243 Ida.[1] It was imaged by the Galileo spacecraft on August 28, 1993; Dactyl was discovered while examining the delayed image downloads from Galileo on February 17, 1994. It was provisionally designated S/1993 (243) 1.[2] The satellite was named after the mythical creatures called dactyls, who, according to Greek mythology, lived on Mount Ida.[3]
