Bad news: Earth is not going to be walloped by asteroid 2006 QV89. Good news: Boffins have lost sight of it, so all hope is not yet lost

Panic-stricken headlines claiming Earth will be slammed by an asteroid on September 9 this year should be ignored, the European Space Agency (ESA) assures us.

The supposedly planet-threatening 100-foot-(30-metre)-diameter space rock, dubbed 2006 QV89, was discovered in August 2006. Following observations over ten days, astronomers predicted it had a 1-in-7,000 chance of crashing into our home world 13 years later in September 2019.

With that date looming, experts at ESA and the European Southern Observatory (ESO) decided to take another look at 2006 QV89 this month, and used the ESO’s Very Large Telescope (VLT), a ground-based observatory in the Atacama desert in Chile, to peer through space at the hurtling rock.

And guess what: they couldn’t find the bloody thing. Tracking asteroids is surprisingly tricky, you know, especially when they’re newly discovered and their orbit paths are not yet confirmed, as is the case of QV89. It's hard to pinpoint where they are in the vast obsidian void, especially more than a decade after they are first seen. Still, as we'll explain in a minute, the boffins persisted in their search because 2006 QV89 is a fairly worrying size.

[...] Since near-Earth asteroid QV89 was observed for just ten days 13 years ago – the same year Twitter was created and no-one outside Apple had yet heard of the iPhone – you can forgive the astronomers for being unable to find the thing in their telescopes this month. However, they didn't give up: by simulating the orbital mechanics of 2006 QV89, they identified the area of space the asteroid would have to travel through if it was to have a serious chance of hitting Earth. And nothing at all was seen in that region: so, no asteroid in that area means no real chance of it hitting our planet. Fingers crossed. [...]

    And this is the current state of our asteroid-impact early warning system. We identified an asteroid with an incredibly high (by asteroid standards) chance of hitting Earth, and didn't bother to look at it again to better determine it's orbit at any point in the intervening 13 years? Not until it's potential impact was only months away, and it would be far too late to do anything anyway?

    Why exactly are we even bothering to talk about how to deflect asteroids if we can't even bother to keep tabs on things that we know might hit us until it would be way to late to do anything anyway? I mean sure, at 30m it (probably) wouldn't do much damage unless we got really unlucky, but it's still exactly the sort of thing we're talking about getting ready for.

      Asteroids are a lot like security vulnerabilities. Everybody wants to find them, and possibly even name them, but after that there's no novelty or marketability left so the researchers move on.

        That's too pessimistic. To predict a large impact far in advance would be a huge achievement. The fact that no large asteroids (> 1 km) seem to be on a collision course is good news.

        The fact that scientists are having trouble keeping track of the asteroids with significant impact probability just means those asteroids are small, which is a good thing.

      I see many statements to the similar above. But really, truly, if it was going to hit.. can you imagine them saying "We're all fucked!"

      I don't know about you, but I'd prefer to not spend the next 2 months with insanity ruling the land. Many people can take this sort of thing calmly, but there is a certain percentage of society that's already right on the brink of fuck all madness.

      And even if you take it well, are you going to want to go to work every day, for the last 2 months of your life?

      Supply chains would break down, food would be a problem in cities, and anarchy would emerge just because people wanted to eat.

        It's pretty clear at this point that humanity is not going to be wiped out by a large asteroid within the next century or three. We may see a worse-than-Chelyabinsk incident that could kill thousands, but within the next decade or two we will be able to detect that kind of event in advance, possibly allowing enough time for city-wide evacuations. Then over the next century, we will see asteroid mining as an economic activity and even better asteroid detection. We'll deflect potential impactors and make a profit off of them at the same time.

    30-metre is now planet-threatening? Chelyabinsk meteor was estimated to be 20m and Tunguska about 150.

      Well, that entirely depends on the velocity. Just like a very small bullet can kill you if it is accelerated to the speed of sound.

      No, I don't know if this asteroid is fast enough to be planet-threatening. My point just is, size is not all that matters.

        In the solar system the typical relative velocity of these objects with Earth is around 20km/s and up to 60km/s for front collisions of objects at perihelion falling from the Oort cloud. Sungrazers could go up to 570 km/s.
        So, no, impact velocity is not a significant factor to upgrade a 30 meter object to such level of threat.
        Of course would it be an extra-solar object then the upper asymptotic bound is the speed of light, and that would be a bad bad day but you won't see it coming anyway.
