Asteroids are rocky objects that orbit the Sun. They range in size from small pebbles to large boulders, and they can be found in all parts of the solar system. Most asteroids are found in the asteroid belt, which is located between the orbits of Mars and Jupiter. However, some asteroids are also found in other parts of the solar system, such as near Earth or in the outer reaches of the solar system.
Asteroids are thought to be leftover debris from the formation of the solar system. When the solar system formed, it was a hot, dusty disk of gas and particles. As the disk cooled, it began to clump together to form planets and moons. However, some of the disk’s material did not clump together, and it remained as asteroids.
Asteroids can be a hazard to Earth. If an asteroid were to impact Earth, it could cause widespread damage. The impact of an asteroid about 66 million years ago is thought to have caused the extinction of the dinosaurs. Today, astronomers are tracking asteroids that could potentially impact Earth, and they are working to develop ways to deflect asteroids if they do pose a threat.
