Asteroid 2012 DA14 is getting bigger and bigger. WTF?

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

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?

I think I'll have a beer in the meantime. Kanpai.

I'm recommending this one at the moment, if you're a beer freak like me.

Japanese beer gets a bad rep, but there's a lot decent brews these days. I'm pretty sure some places in the US stock it. Stone brewery do a really awesome green tea IPA, which is worth tracking down.

do the radioactive ions come for free ?

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..

if it's true than an amateur discovered DA14 in 2012, then is it possible that another similarly sized asteroid could be heading towards Earth and resulting in an impact in say, 6 months ?

NASA said hey discovered the larger ones by now, but I think they meant 100m+ I think.. so I wonder how many 50m ones are yet undiscovered

Yes, I was going to ask this question YESTERDAY!

Please respond Astro....

If Dis-Ass-tro really is a PHD(in some mystery field) Show us the paperwork, you want cred in public it's time to puplicize your credentials, unti you do that IN PUBLIC you are just another NOBODY with "opinions" opinions shared by NASA and other Main Stream orgs. So why ask this Nobody for an "opinion" just because he says he's a phd does not mean it's true this is a public forum and anyone here can make stuff up, just because Obama said he was born in USA, we take his "word" for it. Astro provide us with tangible proof you are trained in astro physics and truly have your phd I will not take your word for it as I will not take obama's word about the nature of his citenzenship.

STOP ASKING THIS SHILL FOR HIS OPINION, it's wrthless!

A couple more, "doomy" follow-up questions.


Sorry, I like to think of all scenarios, my mind tends to go a 1000 miles a minute.. LOL


Is there any chance DA14 will come close to an Earth orbiting satelite and possibly discharge and arc of energy / static electricity, that can fry the systems on that satelite?

Also,

What if DA14 were to hit a satelite, and that satelite hits another satelite, then those two hit even more. Untill all satelites are bumping off of each other and crashing down to Earth.. LOL, okay, I know this is highly, extremly not probable, however a doomer can dream.. LOL (not that I want that to happen, just saying)

Where will the Moon be when this rock passes by?
Where are the gravitational effects calculated at and how accurate can they be ? a Solar event in the next 36 hours could cause a trajectory shift, no?
How about hitting a screw/junk at (whatever speed)?

I'm not sweating it... the whole Elenin shit last year had me crapping my pants, not a good time to be new to GLP! And that nut job MrCometWatch, what a crazy ol bastard.. had me telling friends about Kachinas and all sorts of wacky shit!.

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.

If Dis-Ass-tro really is a PHD(in some mystery field) Show us the paperwork, you want cred in public it's time to puplicize your credentials, unti you do that IN PUBLIC you are just another NOBODY with "opinions" opinions shared by NASA and other Main Stream orgs.

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?
