How does asteroids comets and dwarf planets compare in size and composition?

Asteroids are primarily rocky and metallic bodies found mainly in the asteroid belt between Mars and Jupiter, varying in size from a few meters to hundreds of kilometers in diameter. Comets, on the other hand, are composed mostly of ice, dust, and rocky material, typically ranging from a few hundred meters to tens of kilometers across; they develop tails when they approach the Sun. Dwarf planets, such as Pluto, are larger than most asteroids and comets, with diameters over 1,000 kilometers, and can have a mix of ice, rock, and other materials. While asteroids and comets are generally smaller and have more defined compositions, dwarf planets are larger, with more complex structures and atmospheres.
