Asteorid hit Kerbin!

A good opportunity to get it into the orbit. Not much dV needed to alter the course, Oberth means reducing apoapsis will be cheap, though if I'm not mistaken, it comes from below - in such inclination it is useless, you'd need to do a plane change and that takes both fuel and time. Though if it's a Class E, I'd go for it.

Indeed it happens all the time. And there is absolutely nothing to worry about. Just like Schrödinger's Cat it will only exist if as long as you're looking at it. Nothing will happen when you ignore it.
And if you did focus on it to see the impact still not much will happen. NO crater and NO nuclear winter.

The very first asteroid I ever tracked was dead on-course for Kerbin.  I tracked 3 more to make sure I wasn't misunderstanding something -- nope, just that one.

It is no longer on course for Kerbin.

What the heck are the good for "in orbit" though? Fuel? Science? Real Estate?

Asteroids are incredibly fuel-rich.  They can be 80% ore or more.

Like any other rocket vehicle, though, changing its orbit any significant amount will mean pushing away a large percentage of that weight in reaction, either mined or brought from elsewhere.  So I'm not sold on the economics of asteroid capturing.  Either you've blown away a lot of its fuel to capture it, or you lifted up a ton of fuel to it.  (Unfortunately you can't really aerobrake them, it's like trying to aerobrake a snowcone.)

You might not need to change its orbit significantly, of course, not if you don't need it in LKO, emphasis on L. 

As a midpoint between two places, sure -- you could send a combo-pack of probes to solar orbit, grab an asteroid, and send them off all over the system on fuel you didn't have to lift from Kerbin.

Also, they can make handy bases.  Anything which latches onto an asteroid can share resources and power with anything else that's grabbed it.
