Moons of Saturn

This remarkable image was taken by NASA's Cassini space probe in September, 2011. It includes four of  the planet, Saturn's moons, orbiting along the outer edge of its rings.

Satun's largest moon, Titan (3,200 miles across) is in the background. In the foreground just above the rings is the moon, Diode (698 miles across) . Just beyond the outer edge of the rings on the right is the moon, Pandora (50 miles across), and finally, just in the gap between the first ring cluster and the second is the tiny moon, Pan (17 mles across).

The image above is not an illustration, it is a photograph, made all the more amazing by the fact that Saturn is a billion miles from the Sun... so far, that it takes nearly 30 Earth years for Saturn to make one complete orbit of the Sun.
