Saturn’s moon Daphnis is only five miles in diameter, but its orbit can still make some waves.
The tiny moon travels within the Keeler Gap, a space about 26 miles wide in Saturn’s A ring, keeping it clear. It also causes the edges of the gap to ripple as it swings past.
Two new visualizations by NASA software engineer Kevin Gill illustrate how this interaction might look. "This is one of the many aspects of the Saturn system that I imagine would be absolutely breathtaking if you could see it in person," Gill toldUniverse Today.
