The astronomers found that larger craters, which excavated pits much deeper into the Moon's surface, only increased porosity in the underlying crust. This indicates that these deeper layers have not reached a steady state in porosity, and are not as fractured as the megaregolith.
Dr. Thomas and his team at Cornell University have tried to peer into the mysterious interior of the weird little Space egg that is Methone. They started out with the hypothesis that Saturn's relentless strong gravity pulls the little moon into an elongated shape, just like Earth's own large Moon raises ocean tides on our own planet. Then the team went on to calculate how dense the little moon would have to be for its own gravity to counteract those intense tidal forces and create its strange egg-shape.
Other than the sun, no other celestial body significantly affects the earth as the moon does. It is well know that the moon affects the rise and fall of the ocean tide. Such is the effect of the gravitational pull between the earth and the moon. Jupiter is easily the largest planet in our solar system. To put its size in context, Jupiter is more than 300 times the mass of Earth. Here is the interesting part; Jupiter has 63 moons that orbit it and yet it is not the planet in the Solar System with the most moons. That honor belongs to the ringed-planet Saturn, which has 66 moons identified so far. Pluto, the farthest flung among the nine planets, has been the subject of heated debate on whether it really qualifies to be considered a planet. Nowadays, it is classified as a dwarf planet. Its orbit around the Sun is somewhat heavily elliptical. In fact, there are instances where Pluto is actually closer to the Sun than Neptune, the planet that precedes it.
