From images taken by NASA spacecrafts, this picture mosaic was created of six of the planets in our solar system and the Earth's moon. In the foreground is the Earth rising over the lunar surface with the sun flare at the edge of Earth. Venus is the first planet above the moon, and at the top left to right are the planets Jupiter, Mercury, Mars and Saturn.
