Asteroid 2009 DD45 Misses Earth
March 03, 2009
A small asteroid, designated 2009 DD45, passed the Earth at a distance of 46,000 miles, a near miss in terms of cosmic distances.
Though asteroid 2009 DD45 was just about two hundred feet long, it might have impacted with the force of a nuclear blast.Astronomers are comparing asteroid 2009 DD45 to the rock that caused the Tunguska impact of 1908.
The 1908 impact occurred in Siberia near the Tunguska River and destroyed the taiga forest at a distance of twenty five kilometers around the epicenter.
The Tunguska impact, which was technically an air burst explosion rather than a ground collision, had the force of a multi-megaton nuclear blast.
Had asteroid 2009 DD45 hit a populated area, such as a large city, it would have laid it waste.
Had asteroid 2009 DD45 hit the ocean it would have caused a tsunami that would have devastated coastlines.
The space rock was discovered only two days ago
Asteroid 2009 DD45 suggests that not only greater efforts should be made to detect and track such asteroids before they become a threat, but strategies should be put into place to divert them should they be found to be on a collision course.

Another film along those lines, When Worlds Collide, a remake of a 1950s film based on a 1933 novel, is under development.
