The moons of Saturn (annotated)

This composite image, taken by the NASA/ESA Hubble Space Telescope on 6 June 2018, shows the ringed planet Saturn with six of its 62 known moons.

With a diameter of 1123 kilometres, Dione is the fourth-largest of Saturn’s moons and the largest of the siblings in this family portrait. The smallest satellite in this picture is the irregularly shaped Epimetheus, with a size of 143 x 108 x 98 kilometres.

The image is a composite because the moons move during the Saturn exposures, and individual frames must be realigned to make a colour portrait.
