Watch Newly Discovered Asteroid

This beautiful tracking video shows Asteroid 2013 XY8 buzzing our planet on Tuesday night. It's estimated to be up to 230 feet across, more than three times the size of And we only discovered it four days ago. This could've gotten hairy. The asteroid, estimated to be the size of a space shuttle, left us with just 470,000 miles of breathing room, roughly twice the distance between earth and the moon. Astronomically speaking, that's not a lot of space!
