<h3>What is an asteroid?</h3>

One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.

The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.

These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.
