5283 Pyrrhus /ˈpɪrəs/ is a large Jupiter trojan from the Greek camp, approximately 65 kilometers (40 miles) in diameter. It was discovered on 31 January 1989, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California.[1] The dark Jovian asteroid belongs to the 100 largest Jupiter trojans and has a rotation period of 7.3 hours.[9] It was named after Achilles son, Neoptolemus (also called Pyrrhus) from Greek mythology.[1]
