Just a Matter of "Proportions"...

Caption NASA:"A great, eye-like vortex stares out of Saturn's roiling atmosphere. The storm is wide enough to span the distance from Washington, DC to London. Bright Enceladus drifts past in the foreground.
This view looks toward the unilluminated side of the Rings from about 3° above the Ring-Plane.

The image was taken with the Cassini Spacecraft wide-angle camera on April 23, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 752 nanometers. The view was acquired at a distance of approx. 1,3 MKM (such as about 783.000 miles) from Saturn.
Image scale is roughly 72 Km (about 45 miles) per pixel".
