Asteroids

An asteroid is a small, rocky object that orbits the Sun. They are remnants from the formation of the solar system and are usually found in the asteroid belt between the orbits of Mars and Jupiter. These objects vary in size from small pebbles to hundreds of kilometers in diameter.

Characteristics of Asteroids

Asteroids are made of different materials, including rock, metal, and sometimes ice. Their irregular shapes and sizes make them distinct from planets and moons. They lack the atmosphere and geological activity found on larger celestial bodies.
