Asteroid 4179 Toutatis Will Miss Earth, This Time 301

Posted by timothy
from the jimmy-carter's-revenge dept.
EtherAlchemist writes "National Geographic News reports in this story that a giant, peanut shaped asteroid known as 4179 Toutatis will pass within 1 million miles of Earth on Weds, the 29th. When it does, it will be the closest any known object of this size (3 miles) has passed near Earth in this century. No worry about impact yet, it should pose no threat until at least 2562. An interesting note: the asteroid believed to have caused Earth's biggest mass extinction is thought to have been between 3.7 and 7.5 miles as reported here in 2001." 2004 FU162 came closer, but is a much smaller object.

    Wow! You mean to tell me it's the largest object to pass near here in over 3 years!!!

    OK, one of those things that sounds impressive, then when one thinks a little, isn't all that big a deal...

    what if we knew for sure we would be hit in 500 years? that's long enough to be none of our problems. so would people say "fuck them" and just leave it to some other generation to sort out, or be willing to pay for a huge programme to deflect/destroy it?

    it's a similar problem to global warming, except there are no asteroid-impact-dependent business models funding research and laws like with oil.

      we would regard it as "none of our problem", but the technology would continue to evolve.

      in couple of generations people would start making up some plans to escape from the disaster.

    • If we knew that it was going to hit on the next pass, the logical thing would be to blast it this time after it clears the earth. A small change in it orbit at this point should translate into a large one by the time it comes around again.

      Exactly. The lack of opposition from corporate interests in exactly why international cooperation between governments has so quickly put together a comprehensive and effective solution to defending earth by deflecting asteroids.

      Meanwhile, global warming remains a nearly unknown "problem" ignored by all but a few geeks on specialist websites, never mentioned in the news media or turned into a political issue. The oil barons have buried their dirty secret where no one (but rokzy) knows about it.
    • A much more likely problem than an asteroid hitting the earth is a "supervolcano" eruption. These happen WAY more frequently than giant asteroid hits, and they're just as bad. Yellowstone National Park is a supervolcano that erupts about every 600,000 years. Guess how long since it's erupted? 640,000 years.

        Rely on oil, wave, wind and nuclear power sources for energy and invest in halogen/UV light bulbs to illuminate fields, and research atmospheric cleansing methods. I'm sure researchers would find chemicals that could be released into the atmosphere and make the dust particles condense into heavier particles and wash out of the sky.

      I agree, the media needs to stop hyping up these near misses and write the news story AFTER it hits us.
    • Detonate them in its path and stear it off course into the moon or somewhere else. Almost all our ICBMs leave the atmosphere as it is, and once they leave, it wouldn't take much to guide them where we want them. It would be one hell of a light show for sure.

      • Even if you could somehow take a guidance system designed for putting a warhead just above a target on the ground and destroying it and use it to make a far faster approach to a much, much smaller object and still go off with the required accuracy of timing, you wouldn't be accomplishing much except to add radioactive fallout to the considerable blast, heat and tsunami damage.

        ICBMs typically reach velocities of about 15,000 MPH for their sub-orbital trajectories. Getting into orbit requires about 18,000 MP

    I was just watching something the other day on the History channel about a recent find. A huge lot of dinosaurs buried under meters of volcanic ash - sort of hinting a giant volcano blast may have done all the dirt work.

    I tried to google for some more info, but came up empty-handed. I did find this article [findarticles.com] though, about dinosaurs found in Alaska. It states that if they had managed to adapt to an arctic environment, then the "nuclear winter" effect of a large meteor hitting earth may not hold as much water.

    Then again, I doubt we'll ever truly know - maybe the dinosaurs just got tired of living and went the way of the Heaven's Gate members.

    Anatomically modern humans have been around about a hundred thousand years. That's roughly five or six THOUSAND generations. The chances that we get smacked by an asteroid within the lifetime of the first couple of generations that actually have a chance to see it coming is remote.

    Yes, it would be bad.

    Yes, it's going to happen if we don't stop it.

    No, it's not going to happen in your lifetime.

    No, I'm not giving you lots of money to try to stop one with primitive turn-of-the-millennium technology. When legitimate investments in space travel bring the cost of launch down and our robotics/sensors are better and our deep space propulsion systems are better, THEN I'll vote for spending money on a decent system.

    Or I would, if I wasn't going to die in the global bio-weapons apocalypse of 2027.

    ...and park it at one of the Lagrange points? Something that massive would be much better for an international space station than a few hundred tons in low earth orbit, and it would provide more than enough shielding for any conceivable solar flare.
    • For defense, you want to kick the rocks heading for Earth no matter how slowly, or quickly, they'd hit. For capture, you want to find a rock with small delta-V requirements no matter how far away its closest approach is right now. Two different selection criteria.

      Besides, you probably want to get your shielding material sooner rather than later, and not wait for the approach of a dangerous rock to set your schedule.

  • The asteroid rotates around one axis once every 5.4 Earth days and, in turn, rotates around the other axis once every 7.3 Earth days. As such, "the orientation of the asteroid never repeats exactly," Ostro said.

    It isn't clear to what the orientation is compared (...an observer on a fixed point on Earth?, ...a fixed point in the asteroid's orbital plane?), but at some point it will have the same orientation with regard to anything in a periodic motion relative to it.

    Even if such an object hit Earth, I seriously doubt that it would lead to human extinction. In fact, it probably won't even kill as many people as the tens, or possibly even hundreds, of millions we have killed during the 20th century in two world wars, many other wars, and persistent indifference to humanitarian crises of famine or disease. This may be a young crowd, but those of us old enough who have grown up during the heat of the cold war will probably have less to worry about from a meteor hitting than all those tens of thousands of ICBM the USA and USSR seemed willing to unleash on each other and everyone at a very short notice.

    Many species survived many mass extinction events, and, ironically and in fact, many of such species have been, or are being, driven to extinction by none other than us. Soon we will have successfully driven biodiversity to the minimum we have allowed to survive because we want it, such as dairy and poultry farms, and pets.

    I am willing to bet that the last surviving species on Earth will be humans and microbes.

      The chunks of ejecta from a lunar impact will almost certainly be much smaller than the original body, and very few of them would actually hit Earth. The ones which did might well be spread out over time, also. Faced with a choice between braving a 3-mile asteroid impact on Earth and the debris coming to Earth from impact of the same on the moon, I'll let it hit the moon.

      We do have some meteorites which are known to have come from the moon, so it's proven that stuff kicked off of there can wind up here. [wustl.edu] It's also pretty obvious that the pieces that wind up here are nowhere near as big as what smacked the moon in the first place.
