  Still, just a city wiped. Not exactly Earth's gone. I think apocalyptic asteroids are that dangerous mostly because of high speeds. It's mv^2 after all.

    :facepalm: If you "drop" it on a city, the entire Earth is wiped out. You do know how the dinosaurs were wiped out right? Look up how big that one was and compare sizes.

Quite fast given that ISS which is very close to Earth needs to do 17100mph to keep this small orbit. But you are right 140 miles across would be deadly in any scenario.
