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

A small rocky or metallic body that orbits the Sun is known as an asteroid. Asteroids primarily reside in the asteroid belt, which is located between the orbits of Mars and Jupiter, and they vary in size and composition. While meteoroids are significantly smaller objects that can be fragments of asteroids or comets, the term specifically used for those that orbit the Sun is "asteroid." Comets are composed mostly of ice and dust, which distinguish them from the rocky or metallic composition of asteroids. The term "tiny planet" is not commonly used in astronomy and does not accurately describe the objects in question. Thus, asteroid is the most appropriate term for a small rocky or metallic body orbiting the Sun.
