5436 Eumelos /juːˈmiːləs/ is a mid-sized Jupiter trojan from the Greek camp, approximately 38 kilometers (24 miles) in diameter. It was discovered on 20 February 1990, by American astronomers Carolyn and Eugene Shoemaker at the Palomar Observatory in California.[1] The dark Jovian asteroid has been identified as the principal body of the small Eumelos family and is likely elongated in shape with a longer-than-average rotation period of 38.4 hours.[7] It was named after the Greek warrior and charioteer Eumelus from Greek mythology.[1]
