APOD published this nice image of Helene, one of Saturn’s Trojan Moons. The moon does not orbit the planet, but rather orbits ahead of the planet at one of the Lagrange points leading Saturn in orbit. Both Jupiter and Saturn are known to have these Trojan moons.
Of course, you will need your free pair of 3D glasses to view the anaglyph image. Click on the image to enlarge.
If you don’t have a pair of 3D glasses you can see the 2D image here
