In 2029 an asteroid will enter the earth's atmosphere and dip low enough so that it is below satelights. This pas will nock it ever so slightly off it's course and when it comes back in 2036 it may hit the earth, the chances are around 1 in 1600 but the fact that one exists is scary enough. I've heard a bit about this subject in an astronomy class and was wondering if any one had an opinion or information on it.
