Asteroid 2012 DA14 is getting bigger and bigger. WTF?

So is it true, its diameter was really not 47m but really 65m?

Might want to rerun them calcs astroshillery

watch this :

2012 DA14 is zion D ei(A) one for(4) ....mayan day 14 !!

Academic achievments give no bearing to a persons level of morality

This asteroid passes Earth every year...since 4,5 billion yars ago.

It passes so close, that it can be discovered with 1950's tech.

YET, a spanish amateur discovered it...in 2012.

Well, officially he did, since only idiots can believe that NASA didn't dicovered like 30 years ago.

They just didn't tell about it...

I wonder why. /sarcasm

The Spanish Amateurs name wouldn't happen to be "Wolf Biederman" would it?

Exactly the same I'm thinking. An asteroid very close to earth collision discovered by an spanish amateur and not by NASA who spent millions for searching asteroids. ???????????????????????????????????

oh and NASA says the diameter is 51m

You know they got the trajectory right though, I mean how hard can it be?

Supposedly...


1.8e+08 kilograms = 180,000.000 kilograms

180,000,000kg = ~396,832,071 pounds

~396,832,071 pounds = ~198,416 Tons





Joke, right?

Let's compare some things...

O.K, previous post I had mentioned that 2012 DA14 weighs ~396,832,071 pounds or 198,416 tons. What else can we compare this to, so that we may have a better understanding of it's true weight.

Well, what about the Saturn V rocket? It weighed 6,200,000 pounds - or merely 0.0156237372256135% of what 2012 DA14 weighs.

OK.

What else?

Well the weight of the ISS Space Station is a mere 990,000 pounds... or just 0.0024947580408641% of the weight of 2012 DA14.

Just some food for thought...

Oh and comparing this to Apophis is kind of funny...

Apophis weighs 53,147,152,000 pounds.

That means 2012 DA14 is merely 0.0074666667180962 the weight of Apophis...

This is all quite entertaining..

I asked this question, for Astro, in another thread, but I thought I'd ask it here too incase he doesn't see the other one.

What about a magnetic pull? What if the asteroid is comprised of ferrous metals? Is there any chance it could pass through one of Earths magnetic field lines, one of opposing polarity, and get pulled in... or at least, alter it's course slightly?

Yes, I was going to ask this question YESTERDAY!

Please respond Astro....

This rock is estimated at 170,000 metric tons. The speed it is coming in and flying so close to earth it is without doubt a near miss, and the gravity space shear will create huge displacement of water from the oceans. All U.K military are on red alert for homeland emergency relief.

That's sick.


You don't even know what reality is.



No.
We just know we're right.
We've got the data and the calculations.
All you have is hot air.

Some things can be know with perfect certainty. This is one of them.


Eyup.


Let's get serious.
How about €500.-


Let's make it a €1,000.- and the keys to your car.


You don't know shit.

You're a scientific illiterate, a frigging idiot, and and an arrogant moran.


You don't know that.

This pass will significantly alter its orbit, it actually has to be reclassified.
For all we know it spend most of its lifetime in another part of the solar system


Can.
The sky is big though,and it's a teeny weeny pebble.


Eyup.


Ah, a conspiracy fantasy to handwave away the facts.


Fantasies don't need explanations. Only facts do.



An amateur with access to a really big telescope. (.45m)
Until recently most comets and asteroids were discovered by amateurs.
They have the advantage of having a lot more eyes on the sky than the pros.

After the NASA programmes the La Sagra Sky Survey is actually the most prolific discoverer of NEOs.
They've discovered 5.855 asteroids in total, 49 of them NEOs.



No.
It doesn't.

It's orbit is shaped by the gravity of the Sun and Earth.
It is to small to shape the orbit of Earth.

Which gets me back to the free-floating astronaut and the ISS which masses a 1,000 as much.



No.
Earth's magnetic field is pathetic.
It can catch charged particles, not rocks.



Foot. Meet bullet.


Why, oh why, are there so many morans?

What is your source for the red alert?

Here is a really intersting and informative article about how we can and one day should pull large asteroids into Earth orbit so that we can take advantage of the resouces they can provide.

Yep, specially the ones can focus only on the exact words and not on the meaning of things quoting just the part of convenience. Get a brain, If you have two diferrent "scientific" measures that are exluyents between them, then you have an estimated, but for your tiny little brain maybe that´s too much of brain power to process...

If I was located on the West coast of America, Canada and the East coast of Japan up to Russia, I would be locating 100-200 miles inland to high ground.

Truth is this thing could be 6.5km and going to make a direct earth impact. You would still be getting the same story from NASA.
No sense creating chaos.

But the best quote is this: "the electromagnetic field is pathetic" oficially, you´re a retard.

Thanks,

I'be been doing some reading on this.

"30-60 microteslas for the Earth's magnetic field may not sound like a lot, but when you take into account the total volume of the field, its total energy is extremely large, much larger than any magnetic field generated artificially."

"Magnetic pull? No *way.* Magnetic forces such as that decrease as 1/r^4, and even on earth they are barely enough to swing a compass"

I figure NASA scientists calculate the impact probability for many asteroids, taking in account all the unknowns they can think of (which includes all the things you and I could think off, and a lot more). However I also think they would keep the truth hidden, if one was expected to hit. Unless they could say exactly where it would hit.. then maybe they would tell us to evacuate. Especially for one what isn't "that big" on the grand scale of things.


So yeah, magnetic pull won't effect it anymore than possibly causing it to roll one way or the other..

ill grab the catchers mit bruh.

I can't be bothered to read all the posts. Is it going to hit us or not?

Its size is irrelevant to the trajectory. The former is estimated based on the absolute magnitude with an assumed albedo. Depending on the true albedo it could be smaller or larger than the estimation. By my calcs it could be 47m or it could even be a bit larger than 65m, all the way up to about 89 meters depending on albedo.
