The document summarizes the key features of our solar system. It is made up of nine planets that orbit around the sun in circular paths called orbits. The solar system can be divided into an inner solar system containing Mercury, Venus, Earth and Mars closest to the sun, and an outer solar system containing Jupiter, Saturn, Uranus, Neptune and Pluto. Each planet is then described in more detail, noting their size, composition and other distinguishing features like moons.
