Saturn F ring animation

The moons Prometheus and Pandora shepherd the F ring of Saturn. Their gravity tugging at the particles in the ring creates the ripples seen in this image. The gravity of these shepherd moons serves to maintain a sharply defined edge to the ring: material that drifts closer to the shepherd moon's orbit is either deflected back into the body of the ring, ejected from the system, or accreted onto the moon itself.

Nothing is cooler than Saturn. Nothing.

• I think that no one has reviewed this because no one has any clue what it is. Could you expand the caption or provide more info? Intothewoods29 (talk) 22:55, 27 October 2008 (UTC)
  • I get the gist of what it is - having said which the 'reason' given above doesn't do much to encourage voters. Have a read of the image description page, there's a bit of detail there. I just don't know that this does it for me as far as FPC is concerned, I guess it shows what it intends to, but how it ranks on the scale of all our Saturn pics (without checking, I think there's already more than one featured) I'm not sure. --jjron (talk) 12:51, 31 October 2008 (UTC)

• The phenomenon is important, but wasn't well-explained. I've tweaked it. The last sentence comes from Planetary ring (I was checking I got it right, and then found a better explanation, so thought... why not?) Shoemaker's Holiday (talk) 05:20, 8 November 2008 (UTC)
