I'd also like to see it hit. Most of the Earth is still pretty much empty, so even if it hits the Earth, it will probably end up somewhere where a 2 Megaton burst is relatively unimportant. We can predict where it will hit a long time in advance, so nobody need get hurt. It would be good science, and a media event. For many countries with lots of land it could even be a good foreign exchange earner. And it will encourage governments to stump up the necessary money to map the other asteroids.
Pity it will almost certainly miss. 0.022% isn't much.
IIRC, the main damage from asteroid impacts is the tidal wave resulting from a probable drop in the ocean, which would cause deaths within an order or two of the Indonesian tsunami in '04.

Seems like a good opportunity to bring up existential risks. And A friendly reminder that NASA is in fact pretty damned important.
Thoughts?
