An asteroid a third of a mile across will pass close by the Earth - TopicsExpress



          

An asteroid a third of a mile across will pass close by the Earth on January 26. The space rock, code-named 2004 BL86, is expected to reach a point about 745,000 miles from our planet, or three times the distance to the Moon. Although easily far enough away to be safe, the flyby counts as a narrow encounter in astronomical terms. It will be the closest any asteroid comes to the Earth until the predicted fly-past of another rock,1999 AN10, on August 7, 2027. Latest estimates suggest that AN10, which is 0.6 miles across, could approach as close as 19,000 miles.
