It will not happen—To really take over you would need the support of the Army—he lacks that. If he tried to take power the tanks would roll. Even Hillary would go against him. No, I can’t see this happening and if it does—it would bring about Civil War—a new Confederacy—an end to the USA. Obama’s end would be swift and be more like that of the late Col. Quadaffi.
That may be the modeling program itself or the code. I doubt something that's not much larger than the Empire State Building could effect the Earth's orbit at all. Which is why I view the theory of having satellites slightly shift the orbits of objects to be preposterous. I don't see how a sat can have enough gravity to do that without using thrusters. And in their model videos the satellite never touches the object.
I noticed it too but discounted my observation because the article says the asteriod won't even affect tides.
