Discovered on 31 October 1996 by A. Vagnozzi at Stroncone.
Santa-Lucia is a small Italian village on the green hills of Stroncone where a famous olive oil is produced. The village owes its name to the eponymous saint, who was a protector of eyes. It is the site of the observatory where this minor planet was discovered. The name was suggested by the children of the primary school of Vascigliano.Naming citation (WGSBN Bull. 4, #4, 6), IAU / Minor Planet Center, via NASA/JPL
