The lighter albedo seems to be solid rock while the darker albedo seems to be dust or loose material that has found it's way somehow to the lower spots on Epimetheus.zbvhs wrote:Note the large crater at the top of the side facing us: Material seems to be "falling down" and collecting on the "bottom" wall of the crater. Why do you suppose that is? Gravity gradient?
Since this is such a small body, instead of a "rebound center peak" which would imply something "liquid", could this central peak actually be caused by material from the impacting body? (It would be much like part of a snowball sticking to the side of a building while the rest blasts out radially.)It is thought that the big red circle is a crater and that the smaller circle represents the rebound center peaks from the blast.
A slow impact? The momentum of, at least, a 4km comet would have been needed to separate Janus from Epimetheus in the strong gravitational well of Saturn.Doum wrote:(emc write:Could Epimetheus be a "chunk" from a much larger source?)
Interesting. A good idea to explore.
Can they have been one bigger asteroid that have been hit with the right amount of force to split them apart just enough. A slow impact. May be it can explain all those moonlet in there. They seem to be made of the same composition (icy). Just curious to know. If anyone know some facts about it, please tell. Just curious. TY.
Or, at least, match what's left of the impacted body.FieryIce wrote:

Hyperion has an unusually low density and high porosity whereas Epimetheus has been described as having possibly more of a bedrock layer. I wouldn’t conclude that all those moonlets seem to be made of the same composition. But I would examine the presumed large crater with a rebound center peaks, it’s interesting to note how the size of these presumed craters match the impacted body.
Titan's escape velocity is only 2.64 km/s so Hyperion's (250km?) chunk would have crashed at a pretty low velocity;FieryIce wrote:That is a stretch.Epimetheus's chunk is probably Janus;
Hyperion's (250km?) chunk may have formed "Xanadu" on nearby Titan:
, , , that is against yourself.Most people who browse this forum have a genuine interest in what is going on out there and find your ignorant, self important garbage annoying and embarrassing.
It was an hypothesis based primarily upon your own idea that Epimetheus & Hyperion show clear evidence of moon sized impact craters.craterchains wrote:While, as Art said, "Hyperion's (250km?) chunk may have formed "Xanadu" on nearby Titan: " , and, "Epimetheus's chunk is probably Janus; " may sound possible, it is highly unlikely.

FieryIce says it is a "stretch", but I say it is just about the purest form of BS I have yet to hear.
Art, you are sadly mistaken in ever assuming that I subscribe to the theory that these craters are caused by asteroids, comets, or even so called moons colliding with other so called moons. FieryIce and I, along with many others, have changed our minds about accepting such a "pat answer theory" of these craters forming by so called impactors years ago.It was an hypothesis based primarily upon your own idea that Epimetheus & Hyperion show clear evidence of moon sized impact craters.
Indeed, if the back half of the moons broke off from the impact it would have generated a return (rarefaction) shock wave that might have broken down the central crater peaks as observed on Epimetheus & Hyperion (but not on the intact Mimas).
Why would "trajectories and orbits not have permitted it"?
And what is your own scenario of the aftermath of such violent impacts?
Have a nice day. Broken ArrowBut speaking of theories, I find the audacity of some posters that ridiculously and ignorantly challenge some theories to be of great interest to FieryIce, myself, and many others. Why would such ones post in such a fashion? What is it they want to keep people from thinking about? Is it their fear of truth and reasonable questioning that provokes such blatant lies about evidence provided that causes them to deny such proof?
The research done concerning the theory that Concise and Systematic Crater Chains are positive evidence of alien interaction in our solar system in the past couple centuries was closed a few years ago. The losers of said War in the Heavens having been cast out of heaven and thrown down to the earth would of course have an attitude about that. Just think of the psychological blow that would have been for an intergalactic movement against it's government and the creation of the human race to have been beaten then tossed down here amongst mankind of whom they were so jealous of. Like on broken knee caps, they would deny their fall from such technological advancement and way of life, deny everything and crawl on to their soon final defeat here on earth. Sucks to be "them". Note some of the posters attitudes, quite fascinating.
Great story, you should read the bible with out the religion.
