Not one big enough to cause another great extinction, but small enough to just turn a whole small country and parts of neighboring ones into a huge crater. Will the people who was evacuated out after NASA stated a warning try to rebuild the country after everything has settled down or do they’d become citizens of another country?
Edit: after reading the comments, maybe turning a small country into a crater is too much, what about just level the place, or in any way that make it uninhabitable for a period of time?
It depends on how small the country is.
The Vatican? Italy is pretty hosed for a while and there will be a lot of devastation in the areas.
A crater the size of any small country or large city is going to have massive worldwide weather impacts. the one 65 million years ago has a crater about the size of Belgium. Luxemburg is like 1/10th the area and 1/10 of the damage that wiped out the vast majority of life is going to wipe out a very significant chunk of life. Depending on where it hit, it would most likely cause mass die offs downwind for sure and probably drop the world average temps for years.
I’ll bet there is a website that calculates this stuff, but I don’t time to check one out at the moment.
I don’t think anyone would care about rebuilding a crater while the rest of the world collapses.
There is. Have fun!
Thanks!
That same website also tracks how long it’s been since various sized meteors have hit earth.
