Still, .21 lunar distances at that speed is troubling.

Al Gore denies that asteroids have an impact on earth’s weather.

Which is not to say they can't have an impact on the earth.

“Tonight from the UK (Sep 6/7) this object will be 17th magnitude but by tomorrow (Sep 7/8) it will be brightening rapidly from 16th to 15th magnitude and be accelerating from an apparent speed of about 30 “/min to 50 “/min. “

You might have an easier time seeing Pluto with a 3-inch refractor in Times Square!

unless I missed it they left out a very key piece of information - how large are these and what would have happened if they had made a direct hit on Earth?>

These are 10m and 15m wide asteroids. The one that left the crater in Arizona is 1184m wide. Not totally uncommon for one of these to hit the atmosphere.
