* Congress (both houses) is taking the entire week off.
* NASA had a map earlier with a big red X at the end of the Aleutian Islands.
* There's a UNESCO multi-country Pacific-wide tsunami disaster alert exercise going on Nov 9/10.
* FEMA is taking over the airwaves in a test of the emergency broadcasting system around 3PM on Nov 9.
* FEMA in January ordered millions of emergency meals and I've personally seen the FEMA trucks delivering some of the supplies to Memphis.
* One of the tsunami simulations directly uses the NASA X-marked spot from earlier as the trigger point for the waves [link to thetruthbehindthescenes.files.wordpress.com]

It's not a comet, it's an asteroid that's reported as being 400 meters across. From the photos it looks amazingly spherical for an object this small. Most asteroids that we're familiar with are oblong--only when a planetary-like object is larger does its gravity force it to be this spherical.

The object is moving very fast so it seems unlikely that the Earth-Moon's combined gravity could trap it into a spiral-death orbit. Given the physics involved if it misses the Earth then it would be a hyperbolic path if it's at all affected by Earth's gravity.

I would hazard a guess that NASA has calculated the path to strike the Earth (using one engineer's model) and that other/competing engineers have other mathematical models that would suggest that it will miss. NASA then would be reporting the optimistic version to us, the public, all the while reporting the competing theories to our governments along with the worst-case-scenario version.

So, our government for months has been quietly planning and panicking, all the while lying to us about the possibility that the asteroid could strike the Aleutian Islands.

In theory then, it would cause big waves to hit both east/west directions from the landing zone. Additionally--given the mass of the object--it would pummel the ocean floor after splashing down and cause some serious local damage to the Earth's crust there. Given the plastic nature below the crust I'd then suggest that the shock waves would travel obliquely through the Earth and cause damage around the globe in the form of earthquakes and volcano eruptions.

Remember when the Iceland volcano erupted recently and all flights were grounded for a while? Well, imagine what the skies will be like when, say, ten volcanoes all erupt at once. The sky will be dark for days, at least in theory.

Needless to say, if the asteroid hits the planet in the ocean up there things won't be pretty for a while. It will be much worse if it strikes dry land without the ocean spreading out the impact.
