“What in blazes is our moon doing way out there?
“It’s too far out to be a true satellite of Earth, it’s too big to have been captured by the earth. The chances of such a capture having been effected and the moon then having taken up a nearly circular orbit about the earth are too small to make such an eventuality credible.
But, then, if the moon is neither a true satellite of the earth nor a captured one, what is it?”

Interesting theory, but I doubt it. The more we learn, the less we know.
