Which Saturn satellite does it pass closer to Saturn's rings and at what distance?












1












$begingroup$


I was using Stellarium to watch Saturn from its moon Pan and I saw the rings were very close to this moon. Now Saturn's rings extend for a large distance so several moons see them from close. I was wondering, is it know which Saturn moon passes closer to Saturn's rings and at what distance?

          If you explicitly discount the Encke gap (which Pan orbits in) and the Keeler gap (which Daphnis orbits in) as being part of the ring system, Daphnis would be your answer, as it is a ~8 km object in a 42 km gap. (for comparison, Pan is a ~35 km object in a 325 km gap)



          Really, your answer depends on what you want to consider a moon. There are many objects small enough to be classed as moonlets (several hundred metres across) embedded in the rings, and presumably countless more of smaller size.

            Does Pan and Daphnis go at the same speed than the ring objects?

            Pan and Daphnis go at similar (but not exactly the same) speeds as the ring material at the edges of their respective gaps. All the material in Saturn's rings is orbiting around Saturn, which means the orbital velocity changes with how far out from Saturn the material is. The rings don't move at the same speed around saturn.

          Is this a new Fibonacci Identity?

          Image
          6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
