A planetary system is a collection of celestial bodies that orbit a star, including planets, moons, asteroids, comets, and other objects. The most well-known example is our solar system, which consists of the Sun and its orbiting planets, such as Earth, Mars, and Jupiter. Planetary systems can vary widely in composition and structure, with some having multiple stars or a diverse range of planetary types. They form through the process of accretion from a protoplanetary disk of gas and dust around a newly formed star.
