4754 Panthoos /ˈpænθoʊəs/ is a Jupiter trojan from the Trojan camp, approximately 53 kilometers (33 miles) in diameter. It was discovered during the third Palomar–Leiden Trojan survey on 16 October 1977, by Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at the Palomar Observatory in California.[1] It is likely spherical in shape and has a longer-than-average rotation period of 27.68 hours.[9] The assumed C-type asteroid is one of the 80 largest Jupiter trojans. It was named after Panthous (Panthoos) from Greek mythology.[1]
