Because it wasn't big, bright or noisy. The meteor was relatively small and the noise and brightness was a product of it entering our atmosphere. The meteor, in space, has almost no friction placed upon it. When the meteor entered our atmosphere, the air friction caused the meteor to catch on fire and that's why you saw a bright light.
Very true... How the hell did they miss something so freaking big, bright and noisy...
if the average JOE, can pick it up and capture all the footage and bring in the info like i did to you guys... And i only have a tiny net book and people have phones and dash-cams..
There are a lot of factors at play in the detection of meteors. Are they large? Are they shiny and capable of reflecting light; if so, did we look at it when no light was hitting it? Even if light was reflecting off the rock, were we looking in the right direction? Our space-based satellites can look in 360 degrees on three planes, but their sensors are much more focused. Does anyone think we can take a wide-angle view of open space and find small-car sized meteors with a FOV depth of tens or hundreds of thousands of miles?
You would think BILLIONS of DOLLARS, they would collect all this data before hand and gather enough info to warn what could happen
Thousands of meteors fall from space every day. That's what "shooting stars" are, except the ones we see burn out in the night sky are small - a few ounces to pounds. Large meteors are much less common, but they're more common than you would think. Dozens of meteors strike the earth each year, but the impacts are normally small and unimpressive. The large fireballs in the sky happen a few times each year but they often break up high above the Earths surface, posing no real threat to anyone. Larger meteors striking the Earth is more rare, but it happens every couple years. Mind you, this is only what has been observed on land. Who knows what falls in the oceans that cover a majority of the Earth's surface.
But from what i have learned over the years, that BIG one's like this are not as common as wee all think
Depends on the composition. What would be larger? 10 tons of pure Iron would be much more dense/smaller than 10 tons of a silicate-based stone. Scientists predict this meteor was about 10 feet in diameter at the time of explosion... or, about the size of a Mini Cooper.
must of been pretty big if it weighed 10 tonnes
There was never a concern of the meteor striking Earth. The concern was that the meteor would damage our satellites.
The meteor that fall was part of a bigger meteor, that is on course to fall later. In around 5-6 hours from now
It is all up in the AIR at the moment on weather this other part will enter the atmosphere or just past by
well it seems the other piece of rock is not entering the atmosphere yet
Also, the two were seemingly unrelated since they were traveling in different directions.
Just adding that 10 tons of Iron isn't that large, and that most of the damage was the result of the shockwave caused by the explosion (like in early 1900s Tunguska), and most of the injuries were because of glass from blown out windows or hurt ears. I think only a few people were seriously hurt when a factory partially collapsed when part of the meteor crashed through a wall... the other parts are reported to have crashed in low-population areas like fields.
I think they said it was about 10 tons and to think that 10 tons flying over and exploding while injuring about 1,000 people. They said on the news that it was 1,000 people but on the websites it says something like 100.
For those that are curious, the meteor that passed by Earth (DA14) was 17,000+ miles away from Earth, had a diameter of approximately 150ft and is suggested to weigh almost 200,000 tons. Although we don't know for sure, the Meteor Crater near Flagstaff, Arizona is believed to be the impact site of a similarly sized meteor of similar composition to that of DA14. You can look at pictures and find numbers of the crater, but that would be a large and devastating impact, especially if it hit a populated area like Western Europe, Eastern USA or Eastern Asia.
