Know your enemy!
If an asteroid was on course to hit Earth, one of the best things to know, apparently, would be its composition. The strategy for dealing with it can change depending on what it’s made of. My guess is that it comes down to just how solid and strong it is, and thus how severe the measures taken have to be.
There’s an asteroid that’s a current candidate for Earth smashing, called Apophis. A roughly 0.00002% chance for a hit. In that unlikely event of a coming collision, we actually know what this one’s made of, based on meteorites similar to it that have already hit Earth. All to say, probably a false alarm. Then again, someone won the lottery today, and they had worse odds.
