5041 Theotes /θiːˈoʊtiːz/ is a mid-sized Jupiter trojan from the Greek camp, approximately 42 kilometers (26 miles) in diameter. It was discovered on 19 September 1973, by Dutch astronomer couple Ingrid and Cornelis van Houten at Leiden, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the Palomar Observatory, California.[1] The dark Jovian asteroid belongs to the 120 largest Jupiter trojans and has a short rotation period of 6.5 hours.[7]
