Daphnis and Saturn's rings, Cassini image. Daphnis (far right) is one of Saturn's ring-embedded moons. Here, it is seen creating waves as it orbits within the Keeler gap of Saturn's rings. Daphnis is a small moon, only 8 kilometre across, but its gravity is powerful enough to disrupt the tiny particles of the A ring that form the Keeler gap's edge. Three wave crests of diminishing sizes trail Daphnis here. There is also a faint, thin strand of ring material closer to Daphnis. The data for this image was obtained in visible light at a distance of around 28, 000 kilometres. The Cassini spacecraft has been surveying the Saturnian system since 2004, with its mission scheduled to end in September 2017. Image data obtained by the narrow-angle camera of Cassini's Imaging Science Subsystem (ISS). Image published in February 2017. | |
