The Solar System is a collection of celestial bodies that orbit the Sun, which is a star at the center. It includes eight major planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets vary in size, composition, and distance from the Sun, with Earth being the only one known to support life. In addition to the planets, the Solar System contains dwarf planets like Pluto, moons, asteroids, and comets. The gravitational pull of the Sun keeps these objects in orbit, creating a dynamic and diverse environment in space.
