(15417) Babylon is an asteroid of the main outer belt discovered by the Belgian astronomer Eric Walter Elst on February 27, 1998 at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). Unconfirmed sightings of the asteroid had already taken place on January 8, 1981 under the provisional designation 1981 AY 2 at the Japanese Kiso Observatory .
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbital plane of (15417) Babylon correspond to the Hilda group , a family of asteroids that move in an orbital resonance of 3: 2 with the planet Jupiter around the sun . This group is named after the asteroid (153) Hilda .
(15417) Babylon was named after Babylon on August 6, 2003 , as the capital of Babylonia, one of the most important cities of ancient times . In 2013, sulci, which are furrows or gullies, were named after Babylon on Jupiter's moon Ganymede : Babylon Sulci .
