Exploring Jupiter’s
TROJAN
ASTEROIDS
In 2021, NASA will launch the Lucy mission,
which will investigate two primitive asteroid
populations that congregate at stable points
along Jupiter’s orbital path. By getting a
closer look at these asteroids, called Trojans,
Lucy may revolutionize our understanding of
how the solar system formed. ASTRONOMY: ROEN KELLY
