2012 DA14 WILL hit earth.. Confirmed.

Most of the posters here are not claiming that this will hit, just that this a unique event. Nothing this big has come this close in modern times that we can compare it to. The event in Russia is evidence that impact is not necessary for effect.

That being said ... please consider what your intention participating on this thread is, to inform or berate ???

Also consider a discussion on this thread is still possible by ignoring those that are getting off of themselves ....

Heaven forbid you should pay attention to a post that might contain useful information about the trajectory and uncertainty region of the asteroid... That's fine though, that's your choice, as always. Just don't try to push that choice onto others. Kthnxbye!

Another bit of trivia. Both of Mars' moons are asteroids captured by Mars' orbit. One is orbiting slowly out and away, the other orbiting slowly in, and will eventually impact the surface.

You know, this entire website is specifically geared towards CULTIVATING different anomalies with the intended effect that THOUGHT produces TANGIBLE CHANGE in its ENVIRONMENT, as the environment and thought are both one and the same.

What you always see with astro, is a very well calculated and articulated return back to the "real world"; the world you used to belong to before opening your mind. Now, the big question is why??

Well cattle, your minds are being lead in the direction others want you to keep the "milk" flowing. If you can't see what he is trying to do, I dare you to IMAGINE da14 hitting Washington, D.C. With all your will behind it. It might not happen, but then again, something could. That's the entire purpose of this place. If someone is trying with all their might to get you to THINK AND BELEIVE A CERTAIN THING, well, maybe you should begin to listen to what YOU have to say, because you are doing nothing but joining the reality that they have created. This is all

This wasn't enough to warrant the thread be abandoned yet is it LOL?

No , it's really just a wait and see event OR non-event

Lol like its gonna hit the place it would need GPS .

I was wondering if the solar flares would have any effect on its course by somehow pushing it closer to us?

2018 is the cut off date

all prophecy will be fulfilled prior to such

no flesh will remain upon the earth

we'll all be back in spiritual form

Maybe the Korean satellite has a tractor beam on it and the will pull it in!..........LOL

flare would push away ,sun gravity would pull ?

And what makes you think this is not already another plain of existance .

Well, my fat American ass knows how to spell the word "replies".

Lol, knowing nothing, saying nothing.
Good for you

plane?

lol

it doesn't matter what it is

this is as it will be

Tell that to the people it lands on

Hypothesis under debate, not fact.

You wouldn't be able to

Chew this over folks.........

diameter ~50 meters (+- a factor of two)
D = 50 meters An educated guess based on the spectral class

2012 DA14's absolute magnitude of 24.4 suggests a diameter within a factor of two of about 50 meters.
Nick Moskovitz (Carnegie Institution, Washington, DC) reported that he obtained lightcurves and
spectroscopy shortly after 2012 DA14 was discovered.

Diameter = 50 meters Distance 50km Dense Rock 3000kgm3

Energy before atmospheric entry: 1.41 x 10^16 Joules = 3.38 MegaTons TNT

The average interval between impacts of this size somewhere on Earth is 871.7 year


The projectile begins to breakup at an altitude of 48500 meters = 159000 ft
The projectile bursts into a cloud of fragments at an altitude of 7110 meters = 23300 ft.
The residual velocity of the projectile fragments after the burst is 3.97 km/s = 2.47 miles/s.

The energy of the airburst is 1.26 x 10^16 Joules = 3.01 x 10^0 MegaTons.
No crater is formed, although large fragments may strike the surface.

The air blast will arrive approximately 2.55 minutes after impact.
Peak Overpressure: 4400 Pa = 0.044 bars = 0.625 psi
Max wind velocity: 10.2 m/s = 22.8 mph
Sound Intensity: 73 dB (Loud as heavy traffic)


Diameter = 100 meters Distance 50km Dense Rock 3000kgm3

The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 4.87 km/s = 3.02 miles/s
The impact energy is 1.86 x 10^16 Joules = 4.45 MegaTons.
The broken projectile fragments strike the ground in an ellipse of dimension 0.799 km by 0.565 km

Energy before atmospheric entry: 1.13 x 10^17 Joules = 2.7 x 10^1 MegaTons TNT

The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 6 x 10^3 years


Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed.
Transient Crater Diameter: 1.01 km ( = 0.629 miles )
Transient Crater Depth: 358 meters ( = 1170 feet )
Final Crater Diameter: 1.27 km ( = 0.786 miles )
Final Crater Depth: 270 meters ( = 884 feet )
The crater formed is a simple crater.
The floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 125 meters ( = 410 feet ).
At this impact velocity ( < 12 km/s), little shock melting of the target occurs


The major seismic shaking will arrive approximately 10 seconds after impact.
Richter Scale Magnitude: 5
Mercalli Scale Intensity at a distance of 50 km:

Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably.

Felt by nearly everyone; many awakened. Some dishes, windows broken. Unstable objects overturned. Pendulum clocks may stop.


The air blast will arrive approximately 2.53 minutes after impact.
Peak Overpressure: 2040 Pa = 0.0204 bars = 0.29 psi
Max wind velocity: 4.77 m/s = 10.7 mph

at 10km
The air blast will arrive approximately 30.3 seconds after impact.
Peak Overpressure: 19200 Pa = 0.192 bars = 2.72 psi
Max wind velocity: 41.9 m/s = 93.8 mph

Damage Description:
Glass windows will shatter.
About 30 percent of trees blown down; remainder have some branches and leaves blown off.



Diameter = 100 meters Distance 50km Ocean 1000m

The projectile begins to breakup at an altitude of 49800 meters = 163000 ft
The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 5.23 km/s = 3.25 miles/s
The impact energy is 2.15 x 10^16 Joules = 5.13 MegaTons.
The broken projectile fragments strike the ground in an ellipse of dimension 0.802 km by 0.567 km


The crater opened in the water has a diameter of 1.67 km ( = 1.03 miles ).
= 2.7km3 is instantly pushed aside

For the crater formed in the seafloor:
The result of the impact is a crater field, not a single crater. The following dimensions are for the crater produced by the largest fragment.
Transient Crater Diameter: 33.3 meters ( = 109 feet )
Transient Crater Depth: 11.8 meters ( = 38.6 feet )
Final Crater Diameter: 41.6 meters ( = 136 feet )
Final Crater Depth: 8.85 meters ( = 29 feet )
The crater formed is a simple crater.
The floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 4.1 meters ( = 13.5 feet ).
At this impact velocity ( < 12 km/s), little shock melting of the target occurs.


The major seismic shaking will arrive approximately 20 seconds after impact.
Richter Scale Magnitude: 1.5
Mercalli Scale Intensity at a distance of 100 km:

Nothing would be felt. However, seismic equipment may still detect shaking.


The air blast will arrive approximately 5.05 minutes after impact.
Peak Overpressure: 995 Pa = 0.00995 bars = 0.141 psi
Max wind velocity: 2.34 m/s = 5.22 mph
Sound Intensity: 60 dB (Loud as heavy traffic)

so at 50km on a boat in 1000m of water
The impact-generated tsunami wave arrives approximately 23.7 minutes after impact.
Tsunami wave amplitude is less than 1.94 meters ( = 6.38 feet).

so at 20km on a boat in 1000m of water
The impact-generated tsunami wave arrives approximately 4.73 minutes after impact.
Tsunami wave amplitude is between: 45.9 cm ( = 18.1 inches)?????? and 9.72 meters ( = 31.9 feet)

.....could be much much worst than japans tsunami

Nice presentation, thank you

Mass evacuation is not possible with out collapsing the economy.

In reality, according to leading studies, more people would die from economical fall out in efforts to save a population of a modern city.

There simply isn't enough resources to go around for millions of displaced people.


The most economical option is to let the population die with the infrastructure. Since we are a part of the infrastructure.

Knowing there are thousands of satellites, I wonder if this rock would slow down when it hits this nats nest of steel drifting in it's path. Just enough to get captured in Earths pull.

Of course I know that all of the Mayan predictions are a bunch of hooey. But, the same people who told us that the Mayan calendar ended on Dec 21, 2012 are now telling us of 2013 Mayan predictions. I just find that funny.

You say that as if every pinned post doesn't already accomplish that.

It's actually irrelevant since it's not going to hit, so why are you bumping it?

Better question, why are you still slumming it on an "irrelevant" thread ???

Regardless whether this thing impacts or not, that's some great info.

If it walks like a shill and quacks like a shill, it's a _____......
