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?
F=Ma
30M nad a lot of speed = big boom
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!
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.
“I don’t understand how something not that big causes so much damage.”
The speed is simply UNIMAGINABLE. Tornadoes drive straw into trees, and their top speed is 300 MPH. This rock is coming in at 25,000 MPH.
And 40 meters may not sound big, but try lifting a rock that is just 1 meter - it’s something like 5,000 lbs. This rock is more like 160,000 tons...it’s pretty damn massive and will make one HUGE splash if it hits in the ocean.
Sure. if it were solid, and going 19Km/sec
It’s about the same size as created Barringer crater in AZ, yield was about 20 megatons IIRC. It was a nickel/iron body.
