Yeah! just to think that ridge was created by gravity...

What's wrong with it other than its shape?

You guys are so funny Haha ^^ 
Hornblower, that Gif is really neat !

I hope CICLOPS will soon release full resolutions of this one too..! like they did for Daphnis 
This last mission phase is really exciting..!

Two things I notice:

The equatorial dune has more or less 4 km in height (considering Pan's diameter). Is like an inmense wall rising up to the sky separating the two hemispheres.

And the other thing is that the walls of that sharp dune have clear crater impacts. That's fascinating. What does this tell us about the rigidity of the ridge?

If the ridge is 100m thick, I don't think it has to be rigid to get craters, just compact.  Even a rock going tens of km/s will likely not punch through a that thick layer of loose sand, dust or even snow.

Hmm... I read about Pan looking like that because it had a "molten" core at an early age and it flexed out into that shape due to a high rotation. I see many, including I, have come to the different conclusion. I see how it is orientated to the rings and think that the ridges were created from the collection of ringlet particles. It does not spread out due to its rotation and the same effect that makes large surface formations "drift" towards the equator, in my opinion. It is quite amazing and offers a very interesting picture of moon formation in the rings, and perhaps applicable to planet formation. Should we expect such features to be present in a "not so distant" update to space engine (I know all phenomena will be implemented but I am speaking for the short term in this context) :)

My first thought was perhaps the ridge was formed by ring material settling down onto the surface. The rings themselves are certainly thin enough for that to make sense, though I'm not sure offhand if Pans orbit is of sufficiently low inclination.

If that's right then the ridge is probably an accumulation of fine particles and not very solid. It would still be prone to forming craters though -- Newtons impact depth approximation suggests a fast projectile will be stopped by a loose powder very easily.

Plus a transiting terrestrial planet has been found in the habitable zone of the nearby red dwarf GJ 3053, but more HST time is needed to confirm.

What happens when you try to create a similar shape in Space Engine? Well, the program is not completely happy, but...
