2012 DA14 WILL hit earth.. Confirmed.

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

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

For crying out loud. I will bet someone $20 real money through Paypal that it never hits earth. And if nobody takes me up on the offer, then you know its BS. Ergo, STFU

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

Diameter = 100 meters Distance 50km Dense Rock 3000kgm3

The projectile begins to breakup at an altitude of 48500 meters = 159000 ft
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

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

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

The thread is still a useful medium to get the truth out, but since it's not going to hit us the info isn't terribly relevant.

great information, thank you!

Dr. Astro aka Astromut is right again
as he always has been.
Ignorant superstitious people
questioning him will slink away
after this asteroid performs
just as predicted just as the others
have.
Elenintards? Raise your hands!

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

Well...I didn't just "slink away" when he called
me "ignorant"--I happen to have a family and
job commitments to take care of which means
I have to leave the thread.
It is interesting--NO IT IS ODD TO ME--that someone
who claims to NOT BE A SHILL is willing to be
on this thread for 7 STRAIGHT HOURS bashing anyone
who even remotely agrees with the OP on his theory!
7 hours....doesn't he even PEE?
Anyways. As always, I am impressed when an OP will
stand up to arrogant know-it-alls like this guy!
We will see, won't we.
Cheers!

Sorry they say it's not going to happen. Asteroid 2012 DA14 To Pass Very Close to the Earth on February 15, 2013
February 1, 2013

The small near-Earth asteroid 2012 DA14 will pass very close to the Earth on February 15, 2013, so close that the asteroid will pass inside the ring of geosynchronous weather and communication s satellites. NASA's NEO Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known, there is no chance that the asteroid might be on a collision course with the Earth.

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

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

Worse case scenario, an impact is being hid from us because as a species, we could not maturely handle the potential consequences. We would no longer trust our government, NASA, therefore many hollow point bullets and FEMA would be necessary to protect themselves from some very angry, and disillusioned people.

Just some maybe's here, don't get your panties in a bunch.

about personally...)

7 hours....doesn't he even PEE?

Not that this will matter to you, but I've lost any respect I have had for you in the past ...

So if they are shills, why are they being paid, to always be right.

Someone makes a doom thread. Person comes in with facts. Everyone calls him a shill. Doom doesn't happen...repeat exact same scenario ad naseum

But again, he is just some amateur astronomer so his opinion - although valued and appreciated, is no more accurate that anyone else.

I don't have all the answers, nor have I ever claimed to. I do have some answers though, including where this asteroid is headed in 10 days.

Ah, the false balance fallacy. Actually someone who understands celestial mechanics and has done an in-depth analysis IS going to be more accurate than a layman who has not. Now if this video would just finish saving I could show you...

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

I'm curious-- are you basing your calculations on data you got from your own equipment and observations, or are you basing your calculations on numbers from NASA or something like that?

I often wonder why Astroturd hangs around here since hehas all of the answers.

I don't have all the answers, nor have I ever claimed to. I do have some answers though, including where this asteroid is headed in 10 days.

You are trying waaaay too hard...
