Ans. The Solar System is a collection of celestial bodies that revolve around the Sun due to its gravitational pull. It comprises the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), numerous moons, asteroids, comets, and other smaller objects. The Solar System is structured in a hierarchical manner, with the Sun at the center, the planets orbiting in elliptical paths, and smaller objects primarily found in the asteroid belt (between Mars and Jupiter) and the Kuiper Belt (beyond Neptune).
