Cassini spacecraft taking hi-resolution pics of Saturn's moons

Atlas

 

This small moon is only 30 kilometers, or 19 miles across.  Atlas orbits Saturn in a region called the Roche Division, between the planet's A and F rings, at the outer edge of the main ring system. The outer A ring is seen at the bottom of this view.

 

 

Epimetheus

 

A little larger than Atlas, Epimetheus is 116 kilometers, or 72 miles across.

 

Prometheus

 

Prometheus, 86 kilometers, or 53 miles across, orbits Saturn just inside the F ring, seen at the top of the picture.

 

Tethys

 

Tethys (531km or 319 miles) is dwarfed by Saturn and its rings.  A crescent view like this is impossible to see from Earth.  Reflected light from the rings illuminate Tethys' northern hemisphere.
