It is easy to forget just how large Saturn is, at around 10 times the diameter of Earth and with a diameter of about 72,400 miles [116,500 kilometers], the planet simply dwarfs its retinue of moons. One of those satellites, Tethys [660 miles or 1,062 kilometers across], is seen here at lower right.

This view looks toward the sunlit side of the rings from about 8 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on March 7, 2015 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 752 nanometers.

The view was acquired at a distance of approximately 1.6 million miles [2.6 million kilometers] from Saturn. Image scale is 10 miles [16 kilometers] per pixel. Tethys is slightly closer at 1.5 million miles [2.4 million kilometers] away, for an image scale of 9 miles [14 kilometers] per pixel.
