We all know what happened to the dinosaurs and how catastrophic that was for life on Earth. Well, it turns out that it almost happened again on April 14, 2018.

On that date, an asteroid was detected, that would pass by us within 120K miles – half the distance between the Earth and the moon. Even scarier, scientists only got a few hours of heads up.

With an estimated diameter of 200-350 feet, it was the largest known object to pass so close to us, and it would have devastated our planet.
