The outer planets

This animation shows the motion of the Earth and the remaining outer planets. You can see Earth orbiting the Sun and the tiny dot of Mars swinging round outside it and then the giant planets Jupiter and Saturn. At 20 times the distance of the Earth from the Sun we reach Uranus and further out still is Neptune (30 times the distance of the Earth from the Sun), the last of the major planets.

NB The relative sizes of the planets are shown to scale as are their relative times of revolution and relative distances from the Sun. However the size of a planet is not shown to the same scale as its distance from the Sun. The size of the Sun is not to scale - it is shown for position only.
