Many are clustered between Mars and Jupiter in the main asteroid belt while another group, known as Trojans, both lead and follow Jupiter. Webb will add many new observations to the growing body of research about asteroids, and will help us learn more about the origins and makeup of asteroids, providing clues to the history of how planets moved around in the early solar system. Pictured: Ceres is a dwarf planet in the main asteroid belt between Mars and Jupiter. After launching in 2021, the James Webb Space Telescope will help researchers discover more about the formation of the solar system by observing objects like Ceres in the main asteroid belt with its powerful infrared capability.
