Russian researchers say that the influence of Apophis would be about 37,000 miles per hour. They even believe that the event could happen much earlier, in April 2036, but with a chance of 4 in a million.
For their part, NASA succeeded Apophis's power and said it was not as easy to shine on earth in 2068; with the possibility of one in 250 thousand.
The name Apophis comes from Greek mythology and is the representation of chaos. It is a delicate body of 370 meters in diameter and was discovered more than a decaying line.
