- 1. Small Solar System bodies are objects in the Solar System that are not classified as planets or dwarf planets. They include comets, asteroids, meteoroids, and other minor objects. These bodies are remnants from the formation of the Solar System and provide valuable insights into its history. Comets are icy bodies that develop tails when they approach the Sun, while asteroids are rocky or metallic objects that orbit the Sun. Meteoroids are smaller fragments of asteroids or comets that enter Earth's atmosphere, creating meteors when they burn up. Studying these small Solar System bodies can help us understand the early conditions of the Solar System and the potential hazards they pose to our planet.
