looking for animation of asteroid event

…one of the big ones, y’know? I’d kinda like to see how much of the sphere was immidiately involved.

If you mean how much of the Earth’s sphere, the answer is not much. Although these events are highly energetic, they don’t directly affect a large area. The impact crater from the Chicxulub event believed to have been responsible for the extinction of the dinosaurs has a diameter of about 210 miles, and a depth of about 50 miles–very small in relation to the size of the Earth.

Wouldn’t a crater of 210 miles equate to an ejecta field of thousands of miles? Sounds like a big chunk of the globe to me. i’ll bet it looked cool from the moon!

Oh, sure. And a fireball that nearly engulfed a hemisphere. But you said “immediately involved”, which I took to mean as a direct result of the impact itself. Indirectly the entire globe was affected.

well I figured we could include the area buried whithin the first ten minutes as immidiate

No animation, but this is pretty neat.
