Celestial Wonders around Saturn: Helene and Mimas

Caption NASA:"Mimas (397 Km, or 247 miles across) is seen here just before gliding in front of Helene (32 Km, or 20 miles across), which lays about 192.000 Km (approx. 119.000 miles) in the distance beyond the larger moon.
The limb of Mimas is flattened in the West, where the rim if the large crater Herschel lies.
This view looks toward the lit side of the Rings from about 3° below the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 3, 2007 at a distance of approx. 1,3 MKM (about 800.000 miles) from Mimas and 1,5 MKM (approx. 1 MMs) from Helene.
Image scale is roughly 8 Km (approx. 5 miles) per pixel on Mimas and 9 Km (about 6 miles) per pixel on Helene".
