    The number of NEOs (Near Earth Objects) is in continuous growth. A category of these, the most dangerous, the PHAs (Potentially Hazardous Asteriods) is next to 1000!

    Thanks ricci70 these PHA's are a concern. I have read of some methods to avert potential earth annihilation but they require years of preparation and probably international co-operation. Nudging PHA's off course seems the best approach as trying to nuke 'em might seem to be the Sylvestor Stallone way but doesn't get a front row seat in the space theater of "near extinction object" diplomacy!

    Even then, I wonder if sabotage wouldn't belittle the efforts? What is some fanatic religious group intervened to nudge the PHA on to a certain collision path? I guess that would teach the infidels a lesson!

    (note I don't disrespect Muslims as most are nice and certainly not fanatics)

    Using asteroids has the advantage that it doesn't create large amounts of nuclear waste. You kill the people, but leave their land and resources largely intact. And, yeah.... you can probably cover up your role in causing the catastrophe more easily.


    However: I doubt highly that the actual number of PHA's is growing at all. More likely our ability to detect them is growing, but they were there all along.
