Celebration at the Givatayim Observatory: Asteroid 2012 DA14 appears to be passing through both binoculars and the large telescope computer
It was cold on the observation deck at the observatory in Givatayim, but this did not prevent several dozen citizens, including teenagers and even small children, who came with their parents and asked to see the asteroid passing near the Earth. It was true that you had to strain your eyes a little in the telescope eyepiece to see a small dot moving against the background of the nearby stars in the field of view.
Those watching through binoculars may have seen a wider field, but they too had to strain to see the asteroid itself.
But the real observation was made by some members of the Israeli Astronomical Society in the tower of the telescope, where Shai Halzi sat with a coordinate sheet where it was written every minute where the asteroid would be. He pointed the telescope there and waited and indeed the asteroid did not lie and each time we saw small lines moving up the screen of the telescope's operating computer - at intervals of two seconds.
The talk of the day on the observation deck was the closeness of events between the approaching asteroid and a much smaller meteor that exploded in the morning over Russia. Dr. Yigal Fatal, chairman of the Israeli Astronomical Society, explains. "The great experience is the proximity of the two events. The fact that an asteroid passes by us is nonsense, we have indeed seen asteroids a little further away, but this is not a rare event, the fact that another celestial body crashed on the same day is amazing, and it also contributed to raising the bar of interest to new records."
In the meantime, NASA recently released a video consisting of still images showing the asteroid approaching at around nine o'clock in the evening Israel time (15/2/13). The orbit of the asteroid did not allow photographing from Israel its approach but only its receding. During the approach it was over Indonesia, and for the Israeli observer it was roughly on the horizon.
Australian astronomer Jonathan Bradshaw of the Samford Valley Observatory in Brisbane, photographed the asteroid earlier crossing the night sky at 12:59 GMT or 14:59 Israel time. The video speeds up the asteroid's actual speed by 50 times.
The approach was closely monitored in light of an unrelated and unexpected event - the explosion of a large meteor in the atmosphere over Russia. The shock wave caused by the explosion injured over a thousand people, including 200 children, from window panes that exploded in thousands of buildings. There are also unconfirmed reports of some fragments of meteorites on the ground.
NASA reports that the diameter of the meteor that exploded in Russia is about 15 meters and it was the largest to hit the earth since the Tungaska event in 1908.
For the news in Universe Today
The meteor that hit Russia is not related to the asteroid that passed by the Earth today. This is what NASA confirms tonight. The direction of arrival of the meteor was completely different from the trajectory of asteroid 2012 DA14., indicating that they originated from two different objects.
"We are still collecting information about the meteorite that fell in Russia and are analyzing the initial findings," NASA said in a statement. In the videos of the meteor, it is seen passing from left to right against the background of the rising sun, which means that it is moving from north to south. Asteroid DA14 moves in exactly the opposite direction - from south to north."
An image taken from a European observation satellite also confirmed the direction of the meteor that hit Russia.
For news on the subject in Universe Today
And in the meantime, the UN's outer space office presented just today (quite coincidentally) at a conference in Vienna, a plan to protect the earth from threats from space.
The plan, which they have been working on for 12 years, includes a global warning system for asteroids, and the establishment of a task force that will examine what measures should be developed to repel the asteroid and destroy asteroids or repel them using a "gravitational tractor". The news reported that NASA is tracking the 1,310 largest objects, but they make up only 10% of the bodies that threaten Earth. The plan will be submitted to the General Assembly at its meeting in October.

I don't understand your probability calculations. A basic understanding of what probability is is missing here!!! It's a common error, one that took out o. third'. Simpson is justified in his criminal trial. What safkan should do, is to use Bayez's law and compare 2 probabilities. The first is "what is the probability that a meteor will hit given that there is an asteroid at such and such a distance" and the second is "what is the probability that a meteor will hit given that there is no such asteroid".
And now, for the same reason - we need to compare the danger from an asteroid to other threats, such as earthquakes, epidemics and global warming, and consider where to put the money.
I'm not expressing a position on the subject here, I'm just saying that you need to aim before you pull the trigger.

The hypothesis that the Russian meteorite was a satellite of the asteroid was put forward yesterday by an astronomer, Russian I think. Due to the lack of time, he did not publish his calculations. Mention of this hypothesis is on the talk page of the da14 entry in the English Wikipedia. According to my memory, the mention of that astronomer was in the paragraph titled NAME.
I suspect that such a theory will be raised in the near future with more details. As mentioned in my response elsewhere, the coincidence of the two events is so rare that it is worth checking theories of this kind, since the theories of a connection between the events represent a situation that is much less rare.
Is it possible that the meteorite that hit the Earth was a satellite of the asteroid that passed by the Earth?
That is, the meteorite constantly surrounded the asteroid in circles until the Earth stood in its path and then the collision occurred?

In my responses to another article regarding the asteroid, I also do not easily dismiss the possibility that there is a connection between the asteroid and the meteorite in the Russian Urals.
Without going into the question of the nature of the connection, the coincidence is too rare to be random. A very rough calculation I made, such a coincidence is once in 100,000 years. In fact, it seems to me that the probability of the coincidence is one in a million years, but I didn't want to risk the calculations, so I settled for a more conservative estimate of one in 100,000 years. In my opinion, the possibility that the astronomers are wrong is much less rare than once in 100,000 years, as long as you don't take into account one factor or another.
I am not referring to the rest of your words. I don't have a solid opinion on this.
Father, please leave me an email address if you agree.
I have extensive theoretical knowledge and I would like to help if you agree, even though I am busy studying (PHD).
The asteroid is a wake-up call. Next in line will not be a miracle. Think about our cheapness: it took 1.5 billion years to develop intelligent life in the Earth, and if we follow panspermia more, and we save about 20 billion dollars
To be distributed among the 20-50 nations that can afford it. We do not spare wars. Since it is possible to derive financial benefit from the development technologies: for example, as weapons: interception, ultra-fast detonation,
It will become an economic lever that even countries that are not rich like Israel will be able to participate in.
Hypothesis: Perhaps an asteroid hides behind the meteorite's gravity and is attracted to it, or it is unpredictable in its orbit and unrelated to the asteroid.
When it encounters a more significant mass like the Earth, it is attracted to it and the orbit calculations are correct for an asteroid
Not true for a small mass like the meteorite.
As one of the people quoting Mena (Nisim) here, there is a low-intensity project at NASA, called: HAIV, and also
A small association called B612, who are waiting for a budget for a big project. The technology to intercept asteroids up to 100 meters in diameter, and with a composition of materials not too difficult, is available. "Only" an integration project needs to be carried out: nuclear weapons, missiles, the ability to place the interceptor with an accuracy of meters from the orbit and to overcome the asteroid's high speed of 28000 km/h or more.
