The solar system refers to a celestial system consisting of the Sun, the Earth, and other celestial bodies such as planets, satellites, asteroids, and comets. The most important celestial body in the solar system is the Sun, which occupies the vast majority of the system's mass, while the total mass of other celestial bodies only accounts for 1.35% of the entire mass. The Sun and other celestial bodies are attracted to each other by gravity, maintaining the stable existence of the solar system.
