Really, REALLY far away.

Earth = ~93 million miles from the Sun.
Mars = ~145 million miles from the Sun.

That's a lotta miles!

Well, not mention that Mars could be on the other side of the solar system from the earth when and if this happens. The article didn't say, but if was coming close to Mars and not Earth my guess is that Earth and Mars will be far apart.

Though to be honest, if the earth is near its closest point to Mars and this happened...I'd be a little concerned...very very little, but still. If the Earth was the next largest source of gravity then fragments might head our way if they shot out in our general direction (the earth's gravity would be an insanely weak pull of course). However, I highly doubt their would be much for fragments. The thing is just going to plow into Mars and toss up some dust. It isn't like Mars would shatter like a marble and send huge chunks flying toward Earth.

All the atmosphere a comet might make is going to be eaten by solar corpuscular radiation so it doesn't matter. I don't get it.

Additionally, the amount of H, O, and C, in its myriad of combinations will be trivial compared to the total volume of the atmosphere. Water on Earth, and our atmosphere may have originated from bombardment by comets (bombardment is an important point) but, afaik, current widely supported hypothesis is gas/water vapor released by volcanism.

I'm still not comprehending the size of this thing. 1 megaton is one million tons. This thing has the force of 20 billion megatons. Does that mean 20 billion MILLION tons, or just 20 billion tons?

how many TONS is this? One million times 20 billion? It seems incomprehensible.

Those are missions scheduled on very good launch windows, the moments where Earth and Mars are very close together & on the same side of the Sun. There are times when Mars and Earth are on opposite side of the Sun and it could take more than 2 years to reach.

That's exactly what I was thinking! It's actually a rather exciting thought, even though it would still take a long time for the "terraform" to complete after the event.

how many TONS is this? One million times 20 billion? It seems incomprehensible.

Megaton in this context is energy not mass. So a that means an energy release of 8.4 x 10^22 J.

I have not taken a physics course in awhile but using E = 1/2MV^2, and the Discovery News velocity estimate of 35 miles/s (~54km/s) the estimate of 20 billion megatons gives a mass of 5.7 * 10^10 metric tons or 57 billion tons.

For comparison that puts it over half the mass of the moon. If I did the math correctly (which I cannot say for sure that I did) that makes me a bit skeptical of the estimate.

Edited for clarity.
