The inner section of the solar system is made up of the Sun, Mercury, Venus, Earth and Mars, while the outer solar system planets are Jupiter, Saturn, Uranus and Neptune. Current classification places Pluto under the dwarf planets. The planets are relatively small in relation to the space covered by the entire solar system. Hence, the larger portion of the solar system is space. The planets are in constant motion in their paths, which are called orbits. The Sun falls at the center of the solar system, with the orbits of the planets circling it.
