It was discovered on 8 September 1996, by American astronomer Timothy Spahr at the Catalina Station of the Steward Observatory near Tucson, Arizona, in the United States.[1] The assumed C-type asteroid belongs to the 50 largest Jupiter trojans and has a relatively long rotation period of 21.52 hours.[4] It was named for the ancient Greek city of Thronium mentioned in the Iliad.[2]
