You may need Java on, also this link has been giving a few people issues.

2013 TX68 Mar 5 0.044 LD 30 m
OH, and hello to all the Freepers after a 2 year hiatus. Glad to be back !
what’d you come back to tell us we’re gonna die :)
seriously what kind of damage would a 30 meter do?
I think the one that flattened all that area in Siberia in 1908 was 40m.
Maybe it’ll hit Mecca and do billions of dollars ....
.... in improvements.
that one was HUGE!!
I don’t understand how something not that big causes so much damage.
how fast is it going and if we made a craft the same size and it crashed into earth at that speed would it do the same damage.
Yea just teading some more on it. Estimates are all over the place (60-120m)but when they air burst it does alot of damage. Seems maybe the one in Russia recently (2013?) may have been around 20?
The asteroid that made meteor crater was between 30 to 50 meters.
30M nad a lot of speed = big boom
Depends if it is stony, stony/iron or iron. The meteor that hit outside Winslow AZ produced a crater nearly 3/4 of a mile wide and the meteor itself was probably made of iron and around 50m in diameter.
Looks like they are quite heavy for their size. 2013 russian one was 20m and weighed 13000 metric tonnes, and it was hauling rear end speed wise. Apparently weighed the same as the eiffel tower!
Good Lord!! I see some equation that I couldn’t understand in a million years was posted too :)
We have more science people on this board than political science people.
E=MC2 my friend.
If the M is low, the C must be high to do that damage. So if this 30meter wide object (There isn’t really a 3 dimensional measure at that range.. so it may be a lawn dart or it may be a dime) is going fast enough, it’ll have the E to release.
Imagine diving into a pool from the top of the building. The pool itself has surface tension and as people say “it’ll be like hitting pavement” (It won’t) but imagine instead of just falling from a building you’re shot at the water so fast that the heat of your body touching the water causing it to boil and vaporize in front of you (Super cavitation).
A human body would be travelling at a few tens of thousands of miles per hour, which is about an asteroid of this Apollo type is doing right now. Only it’s about 100 feet across. When it hits the atmosphere it will super heat the 60 some miles of atmosphere we have over our heads and the cavitation of the air in front of it will make a boom easily equivalent to an atomic bomb of one type or another.
Hits water ? it could cause a tsunami like the one that hit Oceania a few years ago. Hits land ? Tunguska to the extreme. The tunguska event (If it was a meteor) never reached the ground. The air under it became so full of energy that the asteroid itself puffed into dust. (There is no crater, only a focal point of energetic explosion)
This is really, really close. I mean at .04 LD, if the accuracy is even in that margin, this is within geo-stationary equipment range.
Thanks Celerity. Here's a pic of what is probably the most recent impact crater caused by an object about that size:

“This is really, really close. I mean at .04 LD, if the accuracy is even in that margin, this is within geo-stationary equipment range.”
Yea .044 is real close. So close Im surprised we are not hearing more about it
Isn’t C constant?
that was actually explained really well in layman terms.
Not easy to do. Thanks :)
My wife tortures me good naturedly for driving her out to Meteor Crater.
She jokingly says it was just a big hole in the ground, just to get a rise out of me to defend it!
I did find it really interesting!
