Question

Within the last three years an Asteroid the size of a football field passed over the earth by sixty miles in Northern America.What scale of impact would we feel on earth? How much damage would this have done to our ailing environment?
Name three well known disasters that would take affect?

Answer 1

Micheal, there have been many more with a smaller one landing in South America, gee, just last week. The impact there was called mass hysteria because many people got sick from fumes. The impact will be-should you survive-that the government will cover it up lest it cause upset and unrest-the people just don't need to know. However, should we all be around in 2012 when apophis (I think) comes by very close and much inside the moon, this may become much more important because a couple of decades later it will pass by again and the third time just might be a charm in 2036 .Someone may figure out tracking these NEO's could be more worthy of our tax dollars than killing our children saving a country that doesn't seem to want to be saved. Right now our current leaders have cut the budget of those trying to find these dangerous asteroids. I guess they need the $ to put a fence up down the Rio Grande because they think people are too stupid to put up ladders. Of course, if they would just enforce the law there would be so many less trying to get in and perhaps a few trying to get out. The best suggestion here has been to take the fence money and repair and build giant levees that we need. It would keep out the illegals just as effectively and help us ward off the tsunami that's coming from your asteroid. And I could go off my diet-there would be no food. #3 End of life as we know it so the rest would not matter.
I did manage to be standing at Old Faithful when the Daylight Fireball of 198? flew over. Gary Kronk has an article about it online. Supposedly it is the closest asteroid to pass through our atmosphere and not hit earth. That story is actually worth hearing. . .

Answer 2

If this football field size asteroid was to strike the earth there would be a could of things that would be important. The time of impact, location and trajectory. All those things aside. First the impact would destroy everything it the immediate strike zone, maybe up to 25-50miles depending on the velocity, earthquakes, tsunamis, and volcanic eruptions could follow. The debris giving off would be managed pretty well by the planet without any lasting side effects. Similar to the Krakatoa eruption. But this is only a guess who really knows what will happen.
