Looking Up to the Giant

Thanks to the illumination angle, Mimas (right) and Dione (left) appear to be staring up at a giant Saturn looming in the background.

Although certainly large enough to be noticeable, moons like Mimas (246 miles or 396 kilometres across) and Dione (698 miles or 1123 kilometres across) are tiny compared to Saturn (75,400 miles or 120,700 kilometres across). Even the enormous moon Titan (3,200 miles or 5,150 kilometres across) is dwarfed by the giant planet.

This view looks toward the unilluminated side of the rings from about one degree of the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on May 27, 2015 using a spectral filter which preferentially admits wavelengths of near-infrared light centred at 728 nanometres.

The view was obtained at a distance of approximately 634,000 miles (one million kilometres) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 85 degrees. Image scale is 38 miles (61 kilometres) per pixel. ~ NASA
