Of more interest to me, would be whether any of the space junk clinging to this asteroid will come loose and head to earth.
This is what some scientists say the meteor which expoded above Russia a few years ago was: a tag-along of the large asteroid which flew by earth during the same time.
Tag-along asteroid fragments, a much more legitimate concern, since the main event is about 40 times farther away than the moon. On the other hand it might be interesting to watch the moon and see if anything hits there. Also, will the moon be nearer or farther from the asteroid at the critical days?
Even stuff originally unrelated to it *could* have been pulled into a different trajectory and over the lifetime of both objects repeated encounters could turn out to be quite a train of debris on similar paths. Stuff the size of a car and smaller would likely burn up or shatter into harmless or less harmful pieces on the way in. The Moon is a different story, but that’s obvious just looking at its visible craters. :’)
