Each of the little Space eggs resides within its own ring arc--which is a fragmentary ring of Saturn. One hypothesis states that glittering ice crystals swarming around in the ring arc might be floating down to the surface of Methone, filling in its impact craters or other rough topography. This is something that is thought to have occurred on two other small, icy moons of Saturn--Atlas and Pan. Icy stuff swarming around in Saturn's rings apparently piled up around each moonlet's equator.
The GRAIL mission determined the internal structure of the Moon in great detail for nine months during 2012. Armed with this the new information, GRAIL astronomers were able to redefine the sizes of the largest impact basins on the lunar surface.
The bottom line is that the moon and fishing are inexorably linked, and it will serve you well to educate yourself as to how it all works. Just understanding the phases of the moon and which are better for fishing than others is of huge importance. As a matter of fact this free e-book will teach you what you need to know, and again it won't cost you anything. It's all free! What could be a better deal than that? I would also suggest that you never forget what the reverend McLain said in the movie A River Runs Through It, "Anyone who does not know how to catch a fish shouldn't be able to disgrace that fish by catching it." To that I say, Amen reverend, Amen!
