The Solar System is a dynamic system comprising the Sun, eight planets, moons, asteroids, and comets. It is located in the Milky Way galaxy and is estimated to be around 4.6 billion years old. Each planet has unique characteristics, with the gas giants being composed primarily of hydrogen and helium, while the rocky planets, including Earth, are more dense. Studying the Solar System offers insight into the formation and evolution of our planet and the universe as a whole.
