NOVA scienceNOW: Doomsday Asteroid
Will a doomsday rock the size of the Rose Bowl hit Earth in 2036? Neil deGrasse Tyson narrates this segment, RT 12:10 and first aired October 3, 2006. The Apoapsis asteroid, the size of a football stadium, is headed towards Earth and should arrive in 2036.

Why do they express any hurry in this matter? The asteroid might hit in 28 years be we don't even know that for sure. Also to start fraticly searching for dangerous asteroids is also a waste of time, the last asteroid that actually dammaged anything was millions of years ago, the next one is not going to come tomorrow.

The most recent large scale event was theTunguska event in which a meteoroid exploded in the atmosphere above a forest in Siberia, wiping 30 sq miles off the map. A 10-15 megaton detonation (1,000 times greater than Hiroshima), all from an object probably the size of a Ford Bronco.
Still, this was 100 years ago and on a much smaller scale than what could potentially occur.

We;ll tell Bush that Saddam Hussein's ghost is hiding on the asteroid and is a major threat. The rock will be gone within twelve hours.
