" They say asteroids hit the moon pretty often, which is how the moon gets its crater, but this one is going to be the biggest asteroid ever to hit it and on a clear night you should be able to see the impact when it happens, maybe even with the naked eye but certainly with binoculars. They made it sound pretty dramatic, but I still don't think it's worth three homework assignments. "
