[QUOTE=mecaguy03;50980874]If this had directly hit a populated area, probably quite a lot of property damage and it could have killed quite a number of people. If it hit near a populated area, probably would have leveled some trees and people would hear a large bang. If it comes down over water which is the most likely outcome then really it does nothing but scare some fish.[/QUOTE]
The Chelyabinsk meteor weighed 13,000 metric tonnes and hit the atmosphere at ~13 KM/s. Had it hit fully intact, it would have released 2,166 Terajoules of energy in total- the atomic bomb Little Boy released only 63 Terajoules of energy. Chelyabinsk could have potentially released 34 times the amount of energy of an early atomic bomb, and this asteroid was, potentially, even larger. If it had hit fully intact anywhere near a populated area, you would have far more issues than a few toppled trees.

Probably would've broken up in the atmosphere frankly.
Also y'all are getting anxious about a space rock when [URL="http://science.nasa.gov/science-news/science-at-nasa/2014/23jul_superstorm/"]civilisation almost ended in 2012[/URL] because the sun got bored. It's a wonder humanity is still standing

Imagine if the mayans were right, but something happened that sped the Earth up a week into the future and fucked up their calculations.
Two months actually. It sounds like a lot but in the cosmic sense it really isn't. Imagine every electronic thing in the world catching fire and shorting out at once. Reactors blow, every peice of civil infastructure in the world blows up, post 1980 cars lock up in motion, every bit of non shielded electronic data in the world destroyed
i'd say it'd be a 25% chance that we'd all be going full on mad max after that. Maybe that's how george should've started fury road
[QUOTE=A B.A. Survivor;50980207]So, what would it even have down if it hit?[/QUOTE]
basically nothing which is why it wasnt detected in time

I don't know what's stupider about this, that Congress thinks that NASA can catalog 90+% of every rock greater than 400ft in diameter in space, or that they're making a big deal over a rock up to 100ft in diameter, which wouldn't have even made it to the ground, had it been pulled into Earth.
There is always a giant asteroid, or meteor, or Arquellian battleship/death ray about to destroy the world, it's better that people don't know about it.

Were lucky that meteorites are usually just a bunch of pebbles stuck together then.
Why couldn't we detect it??
[QUOTE=Firetornado;50988785]Why couldn't we detect it??[/QUOTE]
Cause a meteor in space is insignificantly small compared to how big space is. Literally needle in a gigantic as fuck haystack situation

It's hard to detect objects that aren't luminous.
This is why we sometimes find new planets/dwarf planets in our own solar system that we didn't know about.
[QUOTE=Firetornado;50988785]Why couldn't we detect it??[/QUOTE]
We have yet to invent the Solar System radar unfortunately. For now we will stick to simple observations like light reflecting off an object

Quit bulling, Chelyabinsk meteor hardly announced his presence. I doubt it would have killed more than a handful of people.
