A very interesting perspective. Different kinds of craters results from the intersection of different size impacts and different geological conditions prevailing at the time .

I wonder if that first big meteor would have come in at that angle. Anyway, very cool animation.

GREAT! Now I want to see a similar movie showing the evolution of Earth.

Comment on the front page of scienceblogs:

Many of the moon's craters were formed 4 billion years ago on Greg Laden's Blog.

I didn't realize your blog had been around that long, Greg. :)
