On Friday, an asteroid as big as an office building will pass within a whisker of the Earth, the nearest recorded brush for a space rock of its size. Here’s a look at other encounters where our planet (and others) wasn’t as lucky.
Meteor (or Barringer) Crater The Meteor (or Barringer) Crater in the Arizona desert was formed nearly 50,000 years ago. Eugene Shoemaker, who also co-discovered Comet Shoemaker-Levy 9, was the first to confirm that the crater was formed due to an extraterrestrial impact, making him a pioneer in the field of astrogeology.
