KeelerMoon-PIA07584.jpgS/2005 S1: the "Keeler-Gap" Moon56 visiteCassini's cameras were retargeted to capture the tiny Keeler Gap Moon S/2005 S1, visible at the center and first discovered by Cassini a few months ago. Waves raised in the gap edges by the Keeler moonlet's gravity are clearly visible here. Scientists can use the height of the waves to determine the little moon's mass.
The Keeler moon is 7 Km (about 4,3 miles) across and orbits within its 42-km (about 26-mile) wide gap. The much larger Encke Gap (325 Km, or 200 miles wide) is seen here at the upper right (...). This image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 1, 2005, at a distance of approx. 853.000 Km (or about 530.000 miles) from Saturn. The image scale is 5 Km (3 miles) per pixel. The image has been contrast-enhanced and magnified by a factor of 3 to aid visibility.
