What If Every Asteroid Hit Earth at Once? (SIMULATION)

Sixty-six million years ago, this asteroid crashed into Earth and wiped out most of the life on our planet. Including the biggest, baddest things that ever roamed the planet. Yeah, dinosaurs. If a rock this size hit us today, well, humans would be on the brink of extinction.

Today, we look at the five deadliest asteroids to hit Earth - Either in the past or in the not-so-distant future. And we'll slam them into Earth, all at the same time. Spoiler alert: Earth does not win.
