Pretty much.



Now, don't get me wrong. I don't think this is some small deal, and I don't mean to pass this off as some trivial event.



But the real HUGE, dangerous celestial bodies are stuff like this:

http://neo.jpl.nasa.gov/risk/2013ct82.html

Diameter 0.898 km Mass 9.8e+11 kg

In other words, the thing that hit Russia is 0.00000009% of the size of the thing above.

Even though associating the two objects is reasonable, they are moving tens of thousands of miles per hour relative to Earth in very different directions. If a piece breaks off of an airplane heading east, it will continue to move to the east rather than doing a U-turn to go west.

What remains amazing is that the most impressive meteor strike since the invention of the video camera occurs 15 hours before the nearest predicted flyby of an asteroid... and the two events have nothing to do with one another.

Current diameter estimates for the Russian meteor are on the order of several meters, so less than one tenth of the asteroid that is predicted to fly by today.

I'm not sure what's scarier/more amazing:

1. The fact that this fairly significant meteor(ite) event occurred without warning in spite of the fact that we are constantly monitoring for such things.

2. The fact that even a seemingly sleepy little industrial town in eastern Russia is so blanketed with constant surveillance that footage of the event from dozens of angles is available within hours.

It would nice if this was the only astronomical "surprise" in store for us for a little while.

It wasn't really that significant, though. Only about the size of a car, if even that. Plus, everybody was busy gawking at that other asteroid as, hey we saw that coming a way's away and the odds of two coming so close to the earth on the same day seemed pretty limited.

And Chelyabinsk has over a million residents. Sleepy, maybe. Little, nope.

To be even more correct, "small meteor explodes over Russia." While I'm sure there was a meteorite strike somewhere in Russia or Khazakstan, the news is regarding the explosion of the meteor and the resulting shockwave's damage.

While the size of the thing may not be "significant", I'm going to go ahead and say that 1,000+ injuries certainly is.

Agreed, but a large meteor, or even just a middle-sized one that also passed today, would've made 1,000+ injuries seem like absolute child's play

The one that crashed down/exploded was relatively small is why. They're saying roughly the size of a car...kind of hard to see that coming from space.Or at least easy to miss something that size. Imagine how much you would have freaked out if you'd just finished watching Seeking a Friend for the End of the World. Although I'm sure the huge plume of smoke/debris and windows blowing out scared people plenty.

It was a really small meteor, so it's not all that surprising that no one saw it.

And lots of people in Russia have car cameras.

Only 40ish remain hospitalized, and of them, only two are in serious condition. A vast majority of the injuries are very minor.

I wonder if Russia is an attraction for them, or just unlucky.

I don't follow/have a good memory, but the last big meteor hit was Tunkuska.

Or "potential" meteor hit.

Most of the "injuries" are people cutting themselves on broken windows and stuff like that.

I'm not a specialist, but my quick reading says it was a HUGE Meteoroid or a small Asteroid.

Meteors and meteorites are actually hitting Russia left and right. There were several big meteor(ite) events after Tunguska: Sikhote-Alin (sp) meteorite, Katavsky meteor, Vitimsky meteor and I'm sure I forgot some.

Probably has to do with the fact that Russia is, you know, freaking huge?

NASA estimates meteor was 55 ft (17m) in size, larger than originally thought.

Russia's law system is so corrupt that drivers are almost forced to have dash cams.

I'm fine with that. These videos are awesome.
