Scientists believe that on February 15 there will be an asteroid
that will approach the earth. It is said that it will pass safely but it is
only 17,200 miles above the earth’s surface. It is half the length of a
football field (150 feet) in diameter and has an estimated mass of 143,000
tons. If this were to crash in to the earth it would be equivalent to 2.4
million tons of TNT exploding. The chances
of an asteroid of actually hitting the earth are one in a million chances, but
if it does happen you can see the destructiveness of them.
