What do we call a small rocky body that orbits the Sun?

A small rocky body that orbits the Sun is known as an asteroid. Asteroids are primarily found in the Asteroid Belt, which is located between the orbits of Mars and Jupiter, although they can be found throughout the solar system. These bodies are composed mainly of rock and metal, distinguishing them from comets, which are made up of ice, dust, and other materials.

The term "planet" refers to larger celestial bodies that orbit the Sun and are spherical in shape, having cleared their orbital paths of other debris. "Satellite" typically describes a body that orbits a planet, like the Moon or artificial satellites, rather than directly orbiting the Sun. Comets, while also orbiting the Sun, are characterized by their icy components and tails that develop when they approach the Sun, differentiating them from the rocky composition of asteroids. Therefore, the definition and characteristics of an asteroid align perfectly with the description provided.
