it is only 26 meters
if it hits a resdiential area there might be a problem
that is if it does not burn up on it's way into our atmosphere
so no
we are not doomed

I dunno, that 26 meter asteroid could probably take out a ________ ?????
You sure its not miles? haha

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
none of the known are gonna hit and this is known.
Upon its discovery in 2004, Apophis was briefly estimated to have a 2.7% chance of impacting the Earth in 2029. Additional measurements later showed there was no impact risk at that time from the 210-330 meter (690-1080 foot) diameter object, identified spectroscopically as an Sq type similar to LL chondritic meteorites. However, there will be a historically close approach to the Earth, estimated to be a 1 in 800 year event (on average, for an object of that size).

www.abovetopsecret.com... is this what you are looking for
Asteroid 2012 KA was discovered just today (May 16), and is projected to make its closest approach about 0.0015 AU, or 224,397 kilometers (134,933 miles, .6 lunar distances)

Yea, knowing that 1 LD is 384,401 km (distance from Earth to Moon), even one tenth of that is still very far away from Earth...I believe the closest NEO we need to worry about is the one of Friday 13th 2029

But if it hits a key hole while passing Earth it could come back around in 2036...edit on 25-5-2012 by jhn7537 because: (no reason given)

You can't fire at an asteroid and blow it up, NASA has already ruled that out as a possible solution if one's ever on a flight path for Earth. If you blow up an asteroid with a weapon, it will just break apart into smaller rocks and form a shower of death. NASA is not going with this idea, they actually have NO action plan as of yet. They have ideas in their heads, but no technology to show for it.
An asteroid estimated at 50 meters across explodes above Tunguska, Siberia, blowing down trees across 2,000 square kilometers and killing a thousand reindeer, but apparently no people. Because the stony object exploded in the atmosphere, there's no crater.

Obviously its size, should remove any idea of concern that it might 'be the one'.
The only reason I posted it, is because I have never seen anything ever posted at 0.1 LD.
Just thought I'd throw it out there, and see if anybody else knows anything. Plus, it's been a while since we've had some good asteroid talk on ATS lol.
