better descriptions were in the pop-science media.
Freeman Dyson, in _Imagined Worlds_, 1997, discussed the problem. He points
out that nuking it delivers a lot of energy, but that what is really needed
is
momentum. Given time, he suggests building a mass driver on the asteroid and
letting it work for a decade or so.
There are a few other serious proposals out there as well, a recent one being
a
one-two punch. The first bomb creates a crater to focus the energy of the
second,
and thus divert it.
I'm not sure they know enough about the make-up of the comets & asteroids to
predict the outcome of simply blasting them.
Suppose the rouge whips around the Sun and is deflected by outgassing
into an Earth collision orbit. Not much time to shout Te Deum (when we
see that Icy BM).
WTF? Rouge is a red powder or paste.
Rogue - she's one of the X-Men.
And pretty as well.

Can you tell your opinions on incest and child sex, David?While the global warming industry is hoovering up trillions of dollars, the
solution to a real, proven threat to humanity is apparently 'to pray'.

We are truly living in a scientific dark age.
The CBS article does mention the beginning of a search for near-earth objectssolution to a real, proven threat to humanity is apparently 'to pray'.
