I’m going to say 2036. 2012 I don’t think anything will happen. 2029 however, the asteroid is projected to miss Earth, but when it comes around again in 2036 it has a greater chance of hitting us. No one knows for sure, but from looking at the supposed path of the asteroid in people’s research, it has the greatest chance of hitting us in 2036. Even then I’m doubtful. It is supposed to travel uncomfortably close, between the earth’s surface and the satellites orbiting the earth, but there is still a chance it makes no contact. That’s what I’m hoping for, at least.
