The Full Story
Piazzi’s discovery of Ceres in 1801 was the first hint that there were small bodies orbiting in the gap between Mars and Jupiter. Soon afterward, other asteroids such as Pallas, Juno and Vesta were found, revealing that Ceres was not alone. The growing list of objects led astronomers to identify a broad asteroid belt rather than a single missing planet. This region is now known as the main asteroid belt.
