This displacement reaches as much as 4 km (2.5 mi) at the border of the Keeler Gap , due to the out-of-plane orbit of Daphnis , the moon that creates ...
NASA's Cassini spacecraft sent back images looking over the shoulder of Saturn's rings. See more on Saturn's rings: No telescope on this planet would ever have been able to see this.

Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...

The spots can be several thousands of kilometers wide.
