Mini Moons: Are the moons tiny or are the rings vast? Both, in a way! The moons visible in this image, Pandora and Atlas, are quite small by astronomical standards, but the rings are also enormous. From one side of the planet to the other, the A ring stretches over 170,000 miles (270,000 km), dwarfing these small moons of Saturn. For details, visit: http://go.nasa.gov/1wvngob
