Should Humans Worry About Killer Asteroids?

An asteroid impact likely wiped out the dinosaurs.

Could another one obliterate humanity? The risk of a large asteroid slamming into Earth during your lifetime is relatively low. You have an estimated 1 in 75 million chance of dying in such a catastrophe. A fireworks accident (1 in 50 million), a bee sting (1 in 25 million), or a lightning strike (1 in 10 million) is more likely to take you out.

Despite the long odds, astronomers and scientists keep an eye on the sky for nearby objects that might pose a threat. Now, thanks to technology, you can join them.
