يبدوا أن العلماء إستبعدوا مؤخراً هذا الاحتمال على الاقل خلال هذا القرن :
2029 or 2036: In 2004, it was reported that the asteroid 2004 MN4 (later named 99942 Apophis) had as much as a 1 in 37 chance of impacting Earth on 13 April 2029. The asteroid is about 1,300 ft (400 m) across and its impact would cause local or regional devastation. Further study of the orbit of Apophis found that it will miss Earth in 2029 but could strike in 2036. Still more research concluded that Apophis poses little danger of impacting Earth in the 21st century, but the object should be regularly monitored
