That's still large enough to completely wipe out good sized country or create a tsunami similar to but much larger then the one that happened in the Indian Ocean in 2004.
I guess this means NASA may be getting their money for both SLS and Nautilus-X.
You have to also take into consideration the dust, gases, shockwave and heat generated by the impact.

End of the world has postpone to 2040. ^^A new asteroid, identified by NASA, could potentially hit the earth Feb 5, 2040, even though it is much smaller than the one -- nine miles across -- which wiped out the dinosaurs 65 million years ago.
The UN Action Team on near-Earth objects, which has taken note of the 460-ft asteroid, placed the odds of its hitting the earth at one-in-625, though that could change nearer the time.

A UN Action Team on near-Earth objects (NEOs) noted the asteroid’s repeat approaches to Earth and the possibility — however remote — that 2011 AG5 might smack into our planet 28 years from now.

I used this calculator.
http://impact.ese.ic.ac.uk/ImpactEffects/
Also an improved calculator
http://www.purdue.edu/impactearth
Also the data can be placed in this tool to see what the effect would be though the thermal will be less then an equivalent sized nuclear weapon but air blast will be identical
http://nuclearsecrecy.com/nukemap/
The yield would be around 700 megatons not large enough for significant global effects but the radius of total destruction would be about 40 miles and would pretty much financially ruin what ever county it lands in.
Now if it came down in the ocean the resulting tsunami would be 100+ feet high which would could cause damage even hundreds of miles from the impact site.

If you did the calculations you're awesome!
The main danger that remains is dust. Dust particles reflect sunlight and can cause a huge change in climate. When a huge volcano erupted in the XIX. century, the winter after it were especially cold(I don't remember the name but I'm 100% sure it's not BS).

There were two big eruptions that century Tambora in 1815 and Krakatoa in 1883
http://en.wikipedia.org/wiki/Tambora_volcano_eruption_in_1815#1815_eruption.
http://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa.
The explosion would be similar in size to Tambora but since the sulfur dioxide released likely would be much less the global effects would be closer to Krakatoa.
Not an extinction event but could cause chaotic weather patterns and failed crops in some regions along with several years of unusually harsh winters.
The good news considering the size of the object and the lead time even giving a good shove with a VASIMR propulsion stage or attaching a solar sail should be enough to deflect it off course.
Even the propulsive capacity of a fueled chemical EDS might be enough delta V.
There should be no need for anything drastic like using a nuke.

I think you miss the point
You see, the juxtaposition of the words "UN" and "action" is rather humorous to some of us, given the absolute fucking uselessness of the UN. The "Action Team" will probably still be talking in 2040.

They need to let NASA handle this one as it really would only take a single SLS or 2 Falcon 9 heavy launches to send an automated probe to deal with it.
Of course the longer you wait the harder the problem will be to deal with as more delta V will have to be imparted to the asteroid to cause it to miss Earth.
Though for a last resort a 50 to 100MT nuclear weapon should be able to destroy an asteroid of this size.
An interesting asteroid deflection mission proposal from the 1960s.

Dun misunderstand. XD
The emoticon I used is not targeting at you.. ^^
But targeting at those articles which I've cut and paste.
It's to show that I've not choice but to cut and paste out the whole "UN Action Team" accordingly to the article as a respect to the author. ┐（￣ー￣）┌

Anyone who attended social studies class before/ watch news would know the UN is only effective in asking/requesting for humanitarian aids. ^^

I think there needs to be a policy of having all laptops run a high security Linux or BSD using encrypted filesystems and physical destruction of decommissioned drives.
Something mission critical like the ISS's command and control should not be accessible over the public Internet.
Instead things like this should have their own private net work.
It a much more wide spread problem then just NASA.
This also includes things like power switching equipment for the power grid.
Today too few companies control our digital infrastructure and one exploit can open up too many things to attack.
A good example was admins using Vpro to save time thinking it was secure and then it got cracked causing many systems to become vulnerable.
TPM also has been cracked wide open.
The irony is for the exploits known at the time we had a much more secure digital infrastructure in the 1990s then we do today.
I think for some applications Unix and VMS like OSes should be used and heck don't even use X86 CPUs you need every last bit of security you can get even that provided by having some obscurity of the hardware.
Heck even go as far as having custom IBM and Sparc CPUs running nothing but signed code with all the typical security such as encrypted file systems ,private networks,encrypted network traffic and for the extra paranoid even proprietary protocols.
Ie bring back the concept of the Unix workstation.
the video & artecle here.
The Dextre robot on ISS has successfully complete the robotic refueling mission experiment.
The RRM experiment package simulates performing a refueling on a satellite not designed to be refueled in space.

This video has has greatly increase my respect for Neil deGrasse Tyson.
If I had my way I'd liquidate the TSA,DEA,and ATF and use that money to fund a real space program.
found this while lurking for space art news and stuff,... anyway check it out if you're interested.
made here in Japan
I wonder if Arte likes exotic one of a kind chocolates
NASA to launch five rockets in five minutes to study the upper atmosphere.

It seems Neil Armstrong and Gene Cernan do not support the concept of commercial space fight which is odd as this is the polar opposite of Buzz Aldrin's views.
If you ask me Armstrong and Cernan's views are very archaic as commercial transport to LEO is needed for NASA to be able concentrate on exploring deep space.
Unlike the Apollo era they don't have unlimited funding and have other missions going on as well as commitments to keep with other nations on ISS.

Also found a video of the planned EFT-1 test proposed for 2014.
There is a need to recover hardware that would otherwise either linger in orbit or be lost in re-entry. And kept or staged for re-use at a later time. Like for assembly of other projects when the opportunity arises.
Some news on one of the other companies competing for commercial crew transport.
On April 3,2012 Boeing has successfully completed a drop test on the CST-100 capsule.
