Eurybates

After launch, Lucy will make several loops past Earth to gain the gravitational boost needed to head towards its first target, Eurybates, which it won’t reach until 2027.

The spacecraft’s targets include Eurybates, a 64-kilometre-wide remnant of a massive cosmic collision, and its tiny moon Queta, discovered last year with the Hubble Space Telescope.

Two years later, the spacecraft will fly by the first Trojan asteroid, 3548 Eurybates, which also has a tiny moon, Queta.

Eurybates was once part of another destroyed asteroid.

Scientists are interested in differences between its terrain and that of Eurybates.
