An asteroidâs composition is mainly determined by how close it is to the Sun. The asteroids that are nearest the Sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock.Silicates are very common on Earth and in the Solar System.ut other materials have been found in asteroids, as well. Overview. Asteroids are solid, rocky and irregular bodies that are the rocky remnants of the protoplanetary disk of dust and gas that formed around our young Sun over 4.5 billion years ago.
Asteroids are small, metallic or rocky in composition, and have no atmosphere. Most asteroids orbit the sun within a broad belt located between the orbits of Mars and Jupiter: the asteroid belt. Millions of asteroids are under 0.6 mile (1 kilometer) in diameter, but there are many that are larger.The biggest, Ceres, is 590 miles (950 kilometers) in diameter.-type (metallic) are bright and composed mostly of iron. While most asteroids are located in the main belt, asteroids can be located throughout the solar system. Those with orbits that carry them close by Earth are known as Near-Earth Asteroids (NEAs). They can have the potential to someday strike our planet.
