Earth, sun, center of galaxy align on that date 12/21/2012
Some scientists think polar shift may occur, not likely, but possible.
No asteroid is coming
The farthest observed asteroid is approximately 4,536,358,827,000 kilometers away. Now, assuming that this 'Death Roid' must be beyond this in order to be invisible, and that it is set to hit in 4 years, we can extrapolate a speed. 4,536,358,827,000 km/4 years.
1,134,089,706,750 km/year
8,760 hours/year
129,462,295 km/hour
1,079,252,848 km/hour (Speed of light)
12% SOL
So, the asteroid is going at about 1/8 the speed of light. Let's put this into perspective, shall we?
It's going 1,784 times faster than a supernova's explosion.
It's going 2,740 times faster than the fastest recorded asteroid.
It's going 334,652 times faster than a bullet.
I've heard reports that the size of the asteroid is near-earth sized. Let's assume this is an outlier, shall we? To accelerate the largest known asteroid towards Earth at that speed would require 940,050,815,664,960 newtons of force. That's 6,404,313 times the force of the Hiroshima bomb.
