An asteroid is a small, rocky object that orbits the Sun, primarily found in the asteroid belt between Mars and Jupiter, though they can be found throughout the solar system. Ranging in size from a few meters to hundreds of kilometers across, asteroids are remnants from the early formation of the solar system over 4.5 billion years ago. Studying these ancient space rocks provides valuable insights into planetary formation and the composition of the early solar system. Asteroids also draw scientific and public interest due to their potential impact risk to Earth and their promise as future targets for space missions and resource exploration.
