Answer:
'The First Moon of an Asteroid ever discovered is Dactyl'. It is the Moon of an Asteroid named 'Ida'. This egg shaped Asteroid is only 1.4 kilometres (4,600 ft) in diameter, which is about one-twentieth the size of Ida. It was discovered by Ann Harch, a research specialist at Cornell's Centre for Radio-physics and Space Research, in images returned from Galileo. It was named after the Dactyls, creatures which inhabited Mount Ida in Greek mythology.
