Calculator to assess the impact of an asteroid

What if a giant asteroid crashed into the area near your home? Scientists have come up with an 'impact effects calculator' that lets you work out what would happen if an asteroid hits our planet.

Users can type in the size of their hypothetical asteroid, its speed, what it will hit, its angle of entry and even how far they are from the blast. There is even a helpful drop-down menu of pre-set sizes which include 'school bus', 'humpback whale', 'Empire State Building', all the way up to the ominous-sounding 'small planet'.

The website's algorithms then calculate what the effects of the asteroid's impact would be on the earth's axis, whether there would be a fireball - and what chance of surviving any bystanders would have.

More about the calculator.
