How did the moon form? The "big whack" theory suggests that a Mars-size object slammed into the hot early Earth. The debris that was ejected went into Earth's orbit and gradually came together, forming the moon, the widely accepted theory says. A new lunar-rock study suggests that the moon's insides are a lot like Earth's -- new evidence that the theory of the big whack is on the right track. [Illustration courtesy NASA]

“It’s huge compared to the moons we see around other planets, so it has always been suspected that there was something strange in its origin.”
“Strange in its origin?” That’s because it was created.
I must have been out of town that weekend.
Bush’s fault!
I knew an ole chic once that had a an iron core. Cold.
That the moon has a small iron core has been known for a long time.
bump
whatever or whomever made our earth/moon system, its gravitational pull is what keeps our core molten and thus maintains our van allen belt which protects us from solar radiation.
Chewy caramel center bump.
I wasn't aware that the moon had volcanoes?
Nice try, but we all know you were drivin’.

Cool.
Say what?
At one time, the moon’s craters were all attributed to volcanism. That was laid to rest as a consequence of the Apollo mission astronauts who sampled, examined, and photographed the lunar surface. The volcanic explanation made some sense, but was basically an alibi against impact. The so-called “Late Heavy Bombardment” is ascribed to a 200 million year period beginning 4 billion years ago, putting it waaaay back in time, and farrrrr, farrrrr away from our own.

A giant meteorite struck Earth 1.8 billion years ago, creating Sudbury Basin.
