New wave-making moon S/2005 S1

This new moon, provisionally named S/2005 S1, was first seen in a time-lapse sequence of images taken on 1 May 2005. A day later, an even closer view was obtained, which has allowed a measure of the moon's size and brightness.

The tiny object is in the Keeler gap and the wavy patterns in the gap edges that are generated by the moon's gravitational influence. The new moonlet is about 7 kilometres across orbits approximately 136 505 kilometres from the centre of Saturn.
