The planet was imaged by the Galileo spacecraft in 1994. It measures 56 × 24 × 21 km and is heavily cratered. Ida has a satellite which was named Dactyl. The moon is remarkably spherical with a mean diameter of 1.4 km. The Dactyls of Mount Ida were Daemons, Cretan or Phrygian in origin. Their name means ‘the fingers’. The Dactyls were magicians, credited with the spread, and sometimes the invention, of the Mysteries. To amuse the infant Zeus, they organized the first Olympic Games. (Z 124; LDS)
