Asteroids are small rocky bodies that orbit the Sun, primarily found in the Asteroid Belt between the orbits of Mars and Jupiter. They vary in size, shape, and composition, with some being just a few meters across while others can be hundreds of kilometers wide. Asteroids are remnants from the early solar system, providing valuable insights into its formation and evolution. Many asteroids have irregular shapes and can be composed of metals, carbon, or silicate materials. Some asteroids, known as Near-Earth Asteroids, have orbits that bring them close to Earth, raising concerns about potential impacts. Studying these celestial objects helps scientists understand more about our solar system and the origins of life.
