1:49000 chance of apophis hitting us on the first pass... I beleive the odds are in our favor
I dont think itll happen. and plus , an asteroid its size, may create a decent amount of ejecta and cause the sun to be blocked in some reigons , but the time frame of which wouldnt be signifigant enough to cause any noticeable damage to flora and fauna
I believe that same sorta thing. It is possible, but about the same as the earth blowing up any day. It won't happen because the Mayans didn't finish their calender or anything like that (99.99% sure that it wont happen, if said another way).
