This asteroid impact disturbance is the size of the Pacific Ocean. It occurred 11 years ago.
The image you're looking corresponds to an impact energy measured in Billions of tons of TNT (the largest fusion bomb ever tested was about 50 million tons). An impact like that might well end human civilization.
Damn.....I didn’t think a few hundred meters was large enough. I would have thought at least a mile or more to cause a realistic chance of mass extinction!
We are lucky all the gas giants are in the outer solar system.
