  1. It would be a good idea to bring your attention to the weaved-looking F-ring. Let’s talk about why it looks like that.

    Saturn has a moon named Prometheus. Prometheus has a mean radius of ~43 km, but it’s shaped like a weird potato. It lies within the F-ring (you can see it in this GIF, near the end of the loop; look within and close to the F-ring!), but its orbit is so elliptical that it sometimes goes *outside* the F-ring. When it does this and goes through the F-ring, it attracts the ring material with its gravity, pulling it towards it, and effectively creating a weaved looking pattern. So, basically, gravity and orbital mechanics at work. =)
