Are We Watching A Moon Form?

Scientists have long speculated about how are own moon formed. The current theory is the Impact Theory. It goes like this. When the Earth was still molten, a Mars sized orbit crashed into the moon, shooting out molten material into orbit around the earth. This coalesced into what is now our Moon. Now, it seems, we are witnessing the formation of a new Moon in our Solar System. At the edge of Saturn’s brilliant ring system, the Cassini Spacecraft has spotted what appears to be an icy object, about a kilometer in diameter, drifting into an orbit of its own. This motion is consistent with the current theory of how Saturn’s icy moons formed. (Remember Enceladus, just much smaller). While the process of moon formation around Saturn, with it’s huge gravity and immense ring system, is far different from that on Earth, this development is no less fascinating. The Cassini spacecraft has given us some treats during its study of Saturn, from the hexagonal storm at its pole, to this unbelievably cool photo of earth shown below. Now it seems, we are in for another one. A first in human history, the formation of a moon.
