We will have a close call from an asteroid tonight (Oct 11/12) that will pass well within the Moon's orbit at 26,000 miles above the Earth. It is similar in size to the Chelyabinsk asteroid that exploded over that city on 2/15/14 with over half a million tons of TNT explosive force.

NASA and others will be testing the international asteroid warning network to see how well observations are coordinated.
