Belial Posted October 31, 2010 #1 Share Posted October 31, 2010 (edited) Somewhere out in space there’s a big rock that has our address on it. If an object was sent to strike the asteroid, the rock's course could be subtly changed Throughout geological history, our planet has been hit by a succession of major asteroids and the probabilities suggest further impacts will occur in the future. No-one can say today when these might happen; we haven’t yet identified an asteroid of sufficient size and on a path that gives us immediate cause for concern. But the evidence hints strongly that something could find us sooner or later, and we need to be ready. On average, an object about the size of car will enter the Earth's atmosphere once a year, producing a spectacular fireball in the sky. About every 2,000 years or so, an object the size of a football field will impact the Earth, causing significant local damage. And then, every few million years, a rock turns up that has a girth measured in kilometres. An impact from one of these will produce global effects. click Edited October 31, 2010 by Belial Link to comment Share on other sites More sharing options...
CT2010 Posted November 1, 2010 #2 Share Posted November 1, 2010 An asteroid strike isnt foreseen in the immediate future. Smaller ones may fly by about 60000 miles closer to earth may be anytime. But , they dont pose any danger. There is one that may come again closer by thousands of miles around 2080 AD may be but by then we'll have far better deflection mechanisms in place, to deflect it, in case it poses any danger. Of course, all the countries will have to chip in and pay for it Link to comment Share on other sites More sharing options...
