I know there is plenty of objection to nuking very large asteroids — say, larger than a few miles in length, as the attempt may just break
the asteroid into several large pieces.
However, in the case of Apophis, which is a relatively small asteroid — at 800+ feet, it's actually smaller than a modern cruise ship —
why wouldn't a small tactical nuclear warhead just vaporize it instantly?
I mean, I'm not quite clear on why we need to tamper with Apophis in the first place — chances are, IF it ever actually collides with
Earth in 2029 or other future date, this asteroid is going to impact in the ocean, which might produce a minor tsunami, but it's not going to
be catastrophic. Certainly not as catastrophic as any typical earthquake on Earth.
If there is a chance of it hitting a populated land mass, we're not going to know for certain until the final hours of approach — still, even at
that late date, a small tactical nuke atop a missile would reduce such a small asteroid to gas and dust. Instantly.
Is this Russia plan just a training run for intercepting and deflecting asteroids? It's not worth the money and effort, in my opinion.
