During its 12-year mission, NASA’s Lucy spacecraft will explore eight asteroids. It will explore more asteroids than any previous mission. On its way out to the Trojan asteroids, Lucy will fly by the main belt asteroid (52246) Donaldjohanson on April 20, 2025. There, Lucy will fly by five of these L4 Trojans: Eurybates and its satellite, Queta, on August 27, 2027, Polymele on September 15, 2027, Leucus on April 18, 2028, and Orus on November 11, 2028.
The spacecraft’s orbit will then bring Lucy back to the vicinity of the Earth for another gravity assist, and will take it again out to the distance of (function(d, s, id){
