7641 Cteatus, provisional designation: 1986 TT6, is a large Jupiter trojan from the Greek camp, approximately 70 kilometers (43 miles) in diameter. It was discovered on 5 October 1986, by Slovak astronomer Milan Antal at the Toruń Centre for Astronomy in Piwnice, Poland.[1] The dark D-type asteroid is notably inclined and has longer-than-average rotation period of 27.8 hours.[4] It belongs to the 50 largest Jupiter trojans. It was named from Greek mythology for Cteatus, the conjoined twin and father of Amphimachus.[2]
