Killer Asteroid

Scott Manley writes "Astronomers have found a mile wide asteroid which has a non-zero possibility of hitting the earth i n the next century. Asteroid 1999 AN10 was found on 13th January '99 by the LINEAR system and scientists working in Italy have predicted a close approach in August 2027 and a potential collision in August 2039. This has been kept quiet after the panic last year over 1997 XF11 whic had a similar 'remote' possibility, if 1999 AN10 were to hit it would be a real civilisation killer. " I can't believe scientists are bothing with this stuff when we all know Y2k will kill us all in less than a year anyway.

    >Sometimes I really believe that if you don't think about it, it's really not a threat.

    In the last sixty million years, it seems like there has been at most one truly planet-affecting asteroid collision: the one that may have doomed the dinosaurs. More recently, there was a doozy that carved a sizeable crater in Arizona about 50,000 years ago, and one in Siberia about 100 years ago; no doubt there were a number of others over that same time period. There's no reason to believe that asteroid collisions will change in their frequency, so a truly world-affecting asteroid should be an extremely rare event based on previous history. A Siberia class one is rather more likely, but the question is just how much of our resources do we devote to something that we may not be able to detect in time anyway, may not be able to stop anyway, and may have the unfortunate side-effect of making us even better at killing each other? Reagan's Star Wars speech was in 1983, and 16 years and billions of dollars later it still hasn't come close to realization. I can't see a system that has to go far out into space and blow up something huge (and spread the debris far and wide) doing a whole lot better.

    Please don't call it World War III. "World War III" has traditionally referred to a nuclear exchange between superpowers, while the present situation would more likely lead to a fully-informed air- and ground-forces escalation than to the panicked, uninformed, "get them before they get us" escalation to nuclear exchange of the classic WWIII scenario.

    Given the political importance in the present conflict of international bodies such as NATO and the UN, as well as ethnic and political factions within nation-states, it seems like the present situation would more likely escalate into something resembling a global civil war.

    Besides, "Global Civil War" is what it was called in Robotech. Maybe the "asteroid" is really the SDF-1. :)

    Ya, but the biggest trouble would in the licensing of the planet.


    The Open Earth Initiative (OEI) would write an open letter stating their belief in the new Living Earth Public License (LEPL).


    The Free Space Foundation (FSF) will challenge the OEI's position while claiming that they're not against some company from selling space ships for the great exodus, but that it is necessary for all people to have free access to shuttles. The bar service and food service would cost though.


    "Free Shuttle, not Free Beer" they're heard to say.


    They also insist that since the actual shuttles are licensed under the GPL as derived works (from a GNU editor in the 20th century - see: emacs), that the destination planet be called GNU/World.


    There are currently 15 licenses in the making, and no real work has commenced outside of angry letters and a couple small border skirmishes. The Asteroid is now easily visible in the day sky in the northern hemisphere.


    The latest trajectory reports place the impact in the Western United States near Seattle Washington.

    That was one of the sillier things in that movie. "The size of Texas" puts the asteroid at somewhat bigger (1.5 to 2 times, IIRC) than the asteroid Ceres, largest known in our solar system.
    There's no way you're going to blow that up with any mere collection of nukes, and even if you did, there's no way to avoid having a rain of multi-mile wide chunks falling on you anyway. (Consider - the size of Texas - call it a diameter of 600 miles - means about 40 million mile-wide chunks, distributed evenly).

    The other asteroid movie - "Deep Impact" - at least had the physics a bit more reasonable.

    What a comet. Apollo asteroids come close periodically but we have had the same orbit for millions of years as have they and I would think that we would have been hit by the ones that will hit us by now, the orbits would have to be just perfectly skewed so that we could orbit for millions and millions of years before an impact. I'd worry more about a comet, they find new ones all the time. A comet has much much more kinetic energy than an asteroid so a smaller comet could hit us and mess things up pretty bad.

    Like that Shoemaker-Levy commet, it screwed up Jupiter's crap. The largest recorded explosive release of energy man has ever witnessed (other than the Crab (or was it the horse?) nebula which burned as bright as the sun during day light for a couple weeks a little over 1000 years ago, can you imagine seeing two suns for a couple weeks? That was a spiritual experience back in those days...)

    I would think that the odds of a comet hitting the planet would be pretty good compared to asteroids. It would/will be crazy too, people are packing up and heading for the hills because of y2k, imagine what would happen when they get on the news and say a comet is heading for us and it looks like it will get her in about 6 months...

    It's pretty hard to worry about something we can't see =)

    But this asteroid we can see...

    And it passes close enough to our own planet that they perturb each other, and it passes nearby often enough in the next 600 years that we cannot predict if it will hit us or not, or when.

    After each near miss, of course, we can observe the movement of the asteroid and get a better understanding of its motion, but until it misses we actually don't know if it's going to hit!

    And I quote
    "Among the possible orbital solutions
    there are some that undergo a close approach in August 2027, but no impact is possible. However, the period of the asteroid may be perturbed in such a way that it returns to an approach to the Earth at either of the possible encounter points."

    It goes on to note that their accuracy isn't good for more than a decade after each pass, and that each successive pass makes it worse...

    Not something you want to ignore when there is a greater danger from it, than say, Y2k or something...
