It's like the old saying, you can drop a mouse down a 1000 foot mine shaft, and he will get up dazed but walk away. A rat dies, a man is broken, a horse splashes.
What the frick? That is an old saying???? Never heard it. And I don't quite get it either?
- the mouse lives (ok, got it)
- the rat dies (ok, got it)
- the man dies (but gets 'broken' - huh?)
- the horse dies (and his guts splash??)
A more appropriate old saying is "if you can't stand the heat, does a bear shite in the woods?"

Wouldn't most of it burn up in the atmosphere?
NO. The last remaining chunk will hit this guy in the head and destroy most of Louisiana.

Is this because of the damn government shutdown?

What would an asteroid that size do to Earth?
Obvioiusly hitting a big city is one thing, but hitting the ocean?
Cause a ripple...

Can't we fire a nuke at it and get some target practice?
NO. Start paying your taxes and then maybe later.

Consider your target. The composition, the dimensions....the sheer velocity. You could fire every nuke you’ve got at her and she’ll just smile at you and keep on coming.

I think in general, if the object is small enough that the atmosphere doesn't tear it apart or burn it up completely, then it's small enough to not cause catastrophic damage. Larger objects break apart more easily and actually have a smaller chance of affecting the surface of the earth. It requires a really, really large object to get broken up and the remaining chunks are still large enough to cause major damage.
One interesting aside to all this:
It’s not primarily about size, it’s about energy.
Let’s say we have a killer asteroid and we send Bruce Willis to blow it into gravel.
If that gravel hits Earth, we still all die.
Because even though you broke up the asteroid, it still has the same energy. Except now instead of an impact crater, you have a lot of rock burning up in the atmosphere.
Enough so they you essentially heat up the entire planet so much you melt the crust.

Anyone get a look at this thing? Overcast skies prevented me from seeing anything.

You couldn’t have seen anything regardless.
It was a fraction of the size of the ISS, which is barely visible in spite of being highly reflective and only a few hundred miles up.
This object was tens of thousands of miles away, tiny, and probably had a low albeto.
