'''Sidonia''' ([[Astronomy:Minor planet designation|minor planet designation]]: '''579 Sidonia''') is a [[Astronomy:Minor planet|minor planet]] orbiting the [[Astronomy:Sun|Sun]] that was discovered by the German astronomer [[Biography:August Kopff|August Kopff]] on November 3, 1905. It was named after a character in Christoph Willibald Gluck's opera ''Armide''. The name may have been inspired by the asteroid's provisional designation ''1905 SD''.

This is a member of the dynamic [[Astronomy:Eos family|Eos family]] of asteroids that most likely formed as the result of a collisional breakup of a parent body.<ref name="Veeder1995"/>
