Screaming "Earth Killer! Earth Killer!" is a cry for money, dontcha know.
We should be so lucky. That's actually less likely on two counts. The moon is a smaller target and its sucks less, that is it's gravity is weaker, so it wouldn't bend the orbit of the rock as much as the rock gets closer.
It would be quite a show if should impact the front side (just as likely). I don't know if the near side being in daylight (full moon) or darkness (new moon) would be more spectacular. Maybe the best would be for the impact site to be near the terminator, but in darkness. As the debrie cloud rose into the sunlight, you would be able to see a bright spot appear over an otherwise dark area. During a full moon this would appear as a protrusion from the edge of visible disk.
Hope I make it to 2019. Although most likely it will miss, space is large and mostly empty.
Oh man, are you ever right!
Chicken Littles gotta have those gubmint grants to see if the sky is indeed falling. Or global cooling warming is about to do us in.
Or whatever.
