This chart ranks the largest asteroids in the Solar System by mean diameter, in kilometres. Ceres, so large it is also classified as a dwarf planet, dwarfs all the others in the asteroid belt.
About: Largest Asteroids in the Solar System
Overview of the data behind this chartAI Insight
Ceres, at 939 km across, is by far the largest asteroid, so massive that it is also classified as a dwarf planet and holds roughly a third of the entire asteroid belt's mass. Vesta (525 km) and Pallas (511 km) form a clear second tier, followed by Hygiea (433 km), which some astronomers argue may also qualify as a dwarf planet. After the top four the sizes decline gradually through Interamnia, Europa, Davida and Sylvia down to Juno (254 km). The steep drop from Ceres to the rest shows how top-heavy the asteroid belt is: a handful of large bodies contain most of its material, while the millions of remaining asteroids are mostly small, irregular rocks. Remarkably, all the asteroids combined would still not equal the mass of Earth's Moon.
