Cassini spacecraft gets a glimpse of hidden moon of Saturn

Thanks to new images from the Cassini spacecraft, scientists have detected another tiny moon orbiting Saturn. It's only about four miles across, and was spotted in a gap in Saturn's outer ring. Scientists says this previously unknown moon, being dubbed S/2005 S-One, is about 85-thousand miles from the center of the planet.

It joins another moon called "Pan" that exists within Saturn's shimmering rings. All of Saturn's other moons are outside the main ring system. A planetary scientist at the Space Science Institute says researchers need to continue studying the data to determine the shape of this moon's orbit.

The international Cassini mission was launched in 1997 and took seven years to reach Saturn.
