3548 Eurybates (/jʊˈrɪbətiːz/ yə-RIB-ə-teez) is a carbonaceous Jupiter trojan from the Greek camp and the parent body of the Eurybates family, approximately 68 kilometers (42 miles) in diameter. It is a target to be visited by the Lucy mission in August 2027. Discovered during the second Palomar–Leiden Trojan survey in 1973, it was later named after Eurybates from Greek mythology. This C-type asteroid is among the 60 largest known Jupiter trojans and has a rotation period of 8.7 hours. Eurybates has one kilometer-sized satellite, named Queta, that was discovered in images taken by the Hubble Space Telescope in September 2018.
