Small Asteroid To Pass Close To Earth Tomorrow

Matt_dk writes "A small asteroid will pass very close to Earth this Tuesday. Astronomers are still tracking the object, now designated as 2010 TD54, and various estimates say it should come within anywhere from 52,000 km (33,000 miles) to 64,000 km (40,000 miles) on October 12, with closest approach at approximately 11:25 UT."

    In other news "retired Air Force officer, Stanley A. Fulham", whoever that guy might be, "predicts October 13, 2010 as the date for a massive UFO display over the world’s principal cities". ;-) Given the distance, can we really be sure it is an asteroid ?

  3. Not a lot of advance warning... by Chris+Burke · · Score: 5, Insightful

    I was kinda alarmed when I read the name "2010 T" which means it was discovered in the first half of October, 2010 (as opposed to discovered in the second half via time travel). And in fact TFA says it was discovered Oct 9.

    TFA also says it's a pretty small asteroid only a few meters across, which is a pretty good excuse for not finding it sooner (and makes it Mostly Harmless), but still... More funding to asteroid finding/tracking pls thx.

      It's kinda like that, only the pin is also moving at 7,000 mph

      And the pin is a critical piece of national infrastructure, that costs $10B to replace, with a multi year lead time... and you don't get to toss one ball, but randomly a couple per month, almost all of which we don't know about until after the ball is thrown... I wouldn't expect failure every time, or even a given time, but its gotta happen sooner or later.

    It's not worrisome at all. It was not detected until then because it is very small and poses no threat even if it impacts. It's much easier to find larger objects. If an object large enough to cause a global catastrophe was on it's way toward us, we would have way more advance warning than 3 days with these kinds of efforts.

      Please read article, the distance is measured from the center of the earth. So it is only 28,000 miles from the surface, which is right in the gesynch range, based on size, composition and speed, it could vary more than 2,000 miles during its pass near our big old earth.

    First, yes, because we know about it.

    Second, because this is actually passing much closer than the lunar orbit and is thus not a daily event.

    Third, because we do know about it, but also know it would most likely cause no damage, is information worth conveying.

    Fourth, because some of us are quite interested in space and space objects and the field of asteroid tracking, especially as it relates to near earth objects.

    Fifth, because there's a slim chance we could see it! TFA says you'd need a "moderate" sized telescope, which could mean a lot of things in different contexts. The JPL NEO tracker page gives an absolute planetary magnitude of 28, which if my math is right is 10.8 apparent magnitude ideally (i.e. appears 'full' from our perspective, is roughly spherical etc) Which would be within the capabilities of plenty of amateur telescopes.

    Ultimately and obviously, how much this is newsworthy to you is subjective. But I think it's cool.

    Sure if all you care about is yourself.

    Me, I think it's pretty rational to be alarmed by things with the highest probability of killing me or someone I love, or things with a very low probability of killing me, everyone I know and love, and possibly the entire human species.

    In the latter category asteroid impacts would be less alarming than the Cuban Missile Crisis, but I think my level of concern is commensurate with that reality.

  15. Hype? by Anomalyx · · Score: 2, Informative
    From TFA:

    A five-meter-sized near-Earth asteroid from the undiscovered population of about 30 million would be expected to pass daily within a lunar distance, and one might strike Earth’s atmosphere about every 2 years on average.

    So really this happens all the time.

    If an asteroid of the size of 2010 TD54 were to enter Earth's atmosphere, it would be expected to burn up high in the atmosphere and cause no damage to Earth's surface.

    AND nobody will notice if it does decide to visit our planet. Maybe it will even hit one of those "dead satellites" and do its bit to clean up the junk in geosync for us.

    I suspect this article is nothing but NASA's way of saying "moar $$$ pl0x!!!!!1"

  18. Re:I'm not. by Nyeerrmm · · Score: 2, Insightful

    Alarmed is certainly an overreaction. However, that doesn't mean it should be ignored -- kind of like terrorism. Plus, unlike terrorism, taking precautions on the NEO threat doesn't interfere with civil rights, and hasn't seen significant overreaction on the part of the general public.

    Detection programs cost tens of millions of dollars, and even a mitigation testbed for a modest sized asteroid is only around $500 million. These kinds of programs have scientific benefit as well (and costs are on par with other space science efforts,) so it has value beyond the NEO threat.

    Additionally, the threat is not just from extinction-class asteroids, but smaller asteroids that can cause regional destruction. These are expected to occur on a much more regular basis (hundred-ish years). If something like Tunguska were to occur over a populated area, the material damage would be far greater than the cost of NEO programs, and that doesn't even include loss of life.
