How big would an asteroid have to be to end the world?

Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.

Assuming that the asteroid was the shape of a sphere it would have weighed around 3,135,000,000,000 lbs (1,422,012,079,950 kilos). It left a crater 110mi (177.028 km) across. Originally Answered: How big was the asteroid that wiped out the dinosaurs? it is guesstimated to have been around 6-10 miles in diameter.

It would completely destroy most major cities in the United States. For an asteroid to wipe out most everything on Earth, it would have to be massive. Scientists estimate it would take an asteroid about 7 to 8 miles (11 to 12 kilometers) wide crashing into the Earth.

How does the asteroid-impact hypothesis explain the extinction of the dinosaurs and other species? A strike by a 10-km asteroid would have caused tons of dust and debris to be blown into the atmosphere, blocking the sun for many years.

Would it be possible to shoot down an asteroid that is about to impact Earth? An asteroid on a trajectory to impact Earth could not be shot down in the last few minutes or even hours before impact.
