When I compared the first number to the yield of a KT of TNT, I was going 'holy sh*t!'
Now, we're looking st something only 10 or so times the highest yield of the largest thermonuclear device ever detonated, and while that's substantial, not all of that energy will necessarily be transferred in such a way or place that it will be devastating.
Our lovely dirtball in space still has a lot of unoccupied territory out there, especially the 70% covered by water. An airburst over a populated region would be a mess, though, depending on altitude and location...
Agree...we probably get hit quite a bit by this size rock. But it’s a SMALL ROCK, and not even know it - the big ones are the game changers though.
