Diagram of the Orbits of the Planets and the five known Dwarf-Planets. The orbits of each object is shown as a blue ellipse. All eight major planets and the asteroids orbit the Sun in roughly the same plane, but the orbits of the outer dwarf planets do not. The objects plotted in the diagram moving outward from the Sun are Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, and Eris.
