Pretty Big Rock flying by.

There's a pretty big ateroid that's going to fly by the earth next week.  Closer than most satellites providing TV and cell phone communications. 

It's 50 yards wide.  That's one of the bigger asteroids.

A 50-meter asteroid impacted what would become the United States about 50,000 years ago, levelling the area for 50 miles around, and leaving behind the Meteor Crater in Arizona, though that was made of iron, Yeomans says. Another mysterious object believed to be a meteoroid exploded in the atmosphere above Siberia in 1908, leveling an estimated 500,000 square miles of taiga forest in what has become known as the Tunguska Event.
