back to article Asteroid could SMASH INTO EARTH in 2040

Top space boffins are keeping a close eye on an asteroid that could collide with Earth in 2040. Orbiting rock 2011 AG5 is about 140 metres wide and could come close enough to spur on a crack team of drill-wielding heroes to save the world. The Scientific and Technical subcommittee of the United Nations Committee on the …

    Hypothetically speaking...

    ... what kind of damage could a 140 metre wide asteroid do if it struck Earth?

      Re: Hypothetically speaking...

      Depends on what it's made of, how fast it's going and what angle it hits at. But to give you some perspective, here's what happens when a 50-metre nickel-iron meteor hits:

      Not so bad if it touches down in the middle of nowhere, not so great if it happens in the middle of your road.

      Depends where it landed or if it exploded in the air.

      If it happened over a city it would be catastrophic to the point of no more city

        Catastrophic? Depends on the city.

      50-100MT of TNT or so, depending on speed, density, etc.

      Enough to wipe out a megapolis of your chosing if it lands on top of one. Sizeable tsunami at sea too.

      why is this more news-worthy than Apophis? Is it just because we can practice something on this little rock before the next bigger one comes by?

      Re: Hypothetically speaking...

      It could wipe out an area the size of Greater Manchester.

      Although I doubt we will be that lucky.

          "That worked out just fine" - So, by fine you mean "dominant life-form wiped out, to be replaced by currently insignificant small hiding thingies". Are you, by any chance, not human, but insectile?

            Re: Hypothetically speaking...

            Even if the odds of it hitting are remote, it could be a good opportunity to use it as a "practice run" for when the inevitable happens and we do get a rock that could be a problem.

      A rule of thumb for impacts is to take the size of the object and multiply by ten to get the size of the impact crater.

    In 2040 humanity will be looking up at the sky with a same stupid expression the dinosaurs had when the rock hit them. Instead of terra-forming Mars we'll have wars for oil and water.

    A group in need of a theme song

    "Former Apollo astronaut and NEO specialist Rusty Schweickart, representing the Association of Space Explorers"

    Sadly I have a feeling their numbers will be dwindling in the coming decades... I can see earth, in 2039, people screaming in the streets, looking to the sky and wailing "Association of space Exlporers, where are you?" Before some terrific voice yells out "Explorers...... UNITE!" followed by a montage and associated music, with a few men in their eighties zimmerframing their way to the nearest bus stop.

    On a more serious note, is it wrong to hope that there will be a collision just to see what happens? The rate of "OMG ASTEROID" headlines is only increasing, it's going to be a massive anticlimax if nothing ever happens. El Reg needs a collision or two to get the strike rate up.

      Re: A group in need of a theme song

      It'll happen eventually. The likelyhood of it being in any of our lifetimes is pretty slim, but at some point in the next 20 million years or so the Earth will be hit by an ELE sized asteroid.

    According to the Telegraph...

    "NASA has said that options include deflecting the asteroid by attaching a probe to it and using the extra gravity this would create to steer it away from Earth over the course of millions of light years."

      Re: According to the Telegraph...

      Well that's alright then - I was worried there.

      So do they mean it's many years away (time), many light years away (distance), or the course will be deflected by (whatever unit they really mean) I wonder?

      I'm stopping now, thinking down at that level makes my head hurt.

      Almost anything. You would have to do a galactic risk assessment study first.

      And remember Asteroids Have Rights Too, You Know.

    re: Hypothetically speaking...

    It has been calculated that the Tunguska event could have been caused by an asteroid with a diameter of 60 Metres with solid composition. So, depending on its composition it could cause a lot of damage but not capable of wiping out the planet.

    Unless the Tunguska event was caused by something far more exotic, like a black hole or UFO

    Damage

    For something this size it will probably have a yield of between 100 to 1000 megatons, a 3km crater and a land impact would destroy a large urban area (e.g. New York/Tokyo/London).

    Of course the chances of it hitting a major population zone are slim, a more likely oceanic impact would create a sizeable tsunami that, depending on its location, could affect a considerable number of people.

      Re: Damage

      Just started reading Arthur C Clarkes "Rendez-vous with Rama" and as usual he's almost spot on with his predictions ... that has a catastrophic meteor strike in 2077 which wipes out most of North-Eastern Italy.

      Re: Damage

      that yield similar to wot stiffed Japan. Richter 8-10 sort of scale. BIG but not the end of life as we know it.

      So basically, it wouldn't do a lot really. Not on extinction of the species terms anyway.

      Is there anyway to make sure it hits, for example, Scunthorpe?
