An asteroid is a small rocky body that orbits the sun, primarily found in the asteroid belt between Mars and Jupiter. These celestial objects are remnants from the early solar system and can range in size from a few meters to several hundred kilometers in diameter. Asteroids are considered minor planets and can vary in composition, from rocky to metallic to a combination of both. They have been studied extensively by astronomers and scientists to better understand their formation and composition, as well as their potential impact on Earth. Some asteroids have even been visited by spacecraft for close-up observation and data collection. In addition, the study of asteroids is crucial for planetary defense against potential impacts that could cause catastrophic damage.
