Movement Of Planets In Solar System [Diagram]

This solar system diagram shows the movement of the planets around the Sun, the plane of their orbit, and how they are placed with respect to Earth.

An asteroid belt (dotted area in diagram) sits between the inner and outer planets. The inner planets are Earth, Mercury, Venus, and Mars, and are comprised of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune and are gaseous types.

Uranus and Neptune, the farthest from Earth, can’t be seen with the naked eye.
