Which meteorite will fall on October 12th. An asteroid is approaching Earth
In Russia, March 8 is a non-working holiday. In 2020, it falls on Sunday, which is already a “traditional” day off for Russians. Well, what about Monday? We tell you what kind of day it is - a weekend or a working day.
According to the law, if a non-working day in the Russian Federation falls on an official holiday, then the day off is transferred to the next working day.
Accordingly, Sunday March 8, 2020 becomes a public holiday, and the day off is moved to Monday March 9, 2020.
That is, March 9, 2020 in Russia is a day off or a working day:
* March 9, 2020 is a day off.
Also on this day there is another full moon, coinciding with one of the Supermoons of 2020. If we are lucky with the weather (there will be a clear sky), after sunset we will be able to observe a huge beautiful Moon.
In the future, a revision of pensions for length of service awaits working pensioners ( from August 1, 2020), and military pensioners from October 1, 2020.
Incredible facts
For the vast majority of people, apocalyptic scenarios of asteroids falling on our planet are the result of the imagination of science fiction writers. However, common sense suggests that such an event will happen, sooner or later.
And very soon, October 12, 2017, asteroid 2012 TC4 will pass quite dangerously close to our planet. Despite the fact that the chances of a collision with the Earth are extremely small ( about 0.00055%), such a turn of events cannot be completely ruled out.
Asteroid of 2017
What is known about asteroid 2012 TC4
July 27 and 31, and then 5th of August this year, specialists from the European Space Research Agency observed an asteroid approaching Earth 2012 TS4. The observation was carried out using a complex of 8.2-meter telescopesEuropean southern observatory.
We are talking about the first observations of this small asteroid since its first discovery - that is,from October 4, 2012. At the time of the last observation, asteroid 2012 TC4 was still very far from our planet, at a distance of about 56 million kilometers.
WITHIn 2012, this TC4 could not be observed from Earth. The fact is that the apparent magnitude (that is, a measure of brightness celestial body) of this asteroid was 26,4 , which is very, very small (for example, for the brightest celestial bodies, including the Sun, negative values this measure).
An object with a similar magnitude value in 60 billion times fainter than the planet Saturn when observed from Earth. The asteroid is approaching at speed 14 kilometersper second, becoming lighter. At its closest approach to Earth, the apparent magnitude of asteroid 2012 TC4 will be only 13.
Recent observations of the asteroid have made it possible to clarify information about its size ( from 12 to 27 meters in diameter) and location, and also provided an opportunity for scientists fromCenter research near-Earth objects(CNEOS) NASA(National Aeronautics and Research Administration outer space) calculate its future orbit and the distance at which it will fly past our planet at the moment of closest approach to it.
The obtained calculation results indicate that the closest approachasteroid 2012 TC4 will happen to Earth October 12 this year: the space object will fly at a distance equal to 43500 kilometers from our planet (this is about one-eighth of the distance of the Moon from the Earth). There are also less optimistic forecasts, which, however, are not intended to cause panic: according to them, the space object will not approach the Earth closer than a distance of 6800 kilometers.
Where will the asteroid hit on October 12?
Why is this event interesting?
NASA scientists are eagerly anticipating the upcoming asteroid flyby, planning to use the event as an opportunity test NASA's network of observatories, who are working on a planetary defense program. As part of the program for tracking objects potentially dangerous to our planet, further observations of the asteroid are planned both by NASA and by other astronomers.
Michael Kelly(Michael Kelley) , director of the TC4 asteroid monitoring program at NASA headquarters, emphasized that today the efforts of scientists are aimed at studying this asteroid in order to test the operation of the worldwide asteroid tracking network. According to him, this will make it possible to assess the possibility of identifying a potential real threat from such space objects, as well as assess the ability to respond.
An asteroid is approaching Earth
Is it possible to prevent the threat of a collision in the future?
In order to prevent the threat of an asteroid collision with our planet, it is necessary to detect the corresponding space object in a few years before the expected fall.
Objects with diameter up to several hundred meters They are unlikely to cause a global catastrophe, although they can cause significant destruction if they hit infrastructure.
Another thing is asteroids with a diameter several kilometers: the fall of such an object to Earth is highly likely to lead to global catastrophe followed by mass extinction of all living things.
At the moment, the activities of many planetary defense programs are reduced to the observation and identification of potentially dangerous space objects. Moreover, they began to catalog these objects back in 1947 when was founded Minor Planet Center at the University of Cincinnati, USA.
Today we can talk about a dozen programs tracking near-Earth objects as part of a global project called "Space Security Monitor", however, in reality these programs are loosely related to each other.
It turns out that humanity today is absolutely defenseless against the threat of the fall of a large space object, which could threaten the death of all living things? Alas, this is true. However, a start has been made, future programs are being developed, telescopes are being built, high-precision tracking systems.
And now we can talk about the successful results of this work, which made it possible to predict the time and place of the fall of a space object before its entry into the Earth’s atmosphere.
October 6, 2006 telescope "Catalina Sky Survey" located in Arizona, USA, an asteroid was recorded approaching Earth 2008 TC3. Thanks to the data obtained, appropriate calculations were carried out, which made it possible to accurately determine the time and place of the asteroid fall: a space object with a diameter of 4 meters fell through 19 hours after being discovered in northern Sudan, in the Nubian Desert. If an asteroid were chosen as the crash site Big City, 19 hours could be enough to evacuate residential areas at the expected crash site.
Another question is what humanity is capable of countering the threat from the sky, provided its early recognition? Now, essentially, nothing. However, intensive work is underway to develop potential options for repelling the threat, among which we can mention the detonation of a nuclear explosive device (the topic is covered in the blockbuster "Armageddon"), the so-called kinetic ram (a huge artificial object crashing into a small asteroid), an asteroid gravity tug, focused solar energy, an electromagnetic catapult and a number of other options.
Fallen asteroids
Why couldn't they detect the Chelyabinsk meteorite before it entered the atmosphere?
September 1this year, NASA experts observed the approach of the largest space object in the history of observations - asteroid (3122) Florence. The fall of this object onto the surface of our planet would hardly leave any chance for its inhabitants.
However, Florence passed at a distance of about 7 million kilometers from the earth. It is reported that asteroids with a diameter of up to 10 meters. Why then did the approach of the famous Chelyabinsk meteorite, the diameter of which was, according to various estimates, from 17 to 20 meters?
A large asteroid called 2012 TC4 is rapidly approaching Earth. Where will a meteorite fall if it doesn't fly past? While the attention of astronomers around the world is focused on this celestial body, the world is making one after another guesses about the end of the world. Will TC4 put an end to all life on Earth?
Asteroid 2012 TC4 – what is it? Where will it fall in October 2017 and will it fall at all?
Asteroid 2012 TC4 was most accurately studied in 2012, when it once again passed by Earth. In 2015, calculations yielded shocking data: an asteroid will pass in frighteningly close proximity to our planet in 2017. The portal Astwowatch reported about this, and now, as the asteroid approaches the Earth’s orbit, people are talking about it more often.
At the moment, its dimensions are known - approximately. As the source notes, the meteorite has an elongated shape up to 40 meters in diameter. For comparison: the famous “Chelyabinsk meteorite” was 17 meters high.
The problem is that it is impossible to say for sure whether an asteroid will collide with Earth. At the moment, astronomers have not been able to assess and study the threat thoroughly. It is now unknown what the celestial body that threatens us consists of. Meanwhile, if it is a rocky meteorite with an ice core, it will burn up in the atmosphere and remain practically unnoticed. It’s another matter if the space guest is a combination of space rocks and metal. In this case, the area of impact will be unrecognizable - the shock wave and debris will cause enormous damage within a radius of tens of kilometers and will leave a huge crater at the epicenter. Then experts will be able to study it with passion, if they are alive, of course.
According to an expert interviewed by AiF, asteroid 2012 TC4 can fly 115 thousand kilometers from Earth.
Such a meteorite could only be seen through a powerful infrared telescope.
The flight path of asteroid 2012 TC4 will be “tangential” from the Earth. Considering the trajectory, size and distance of the flight path from Earth, there is nothing to worry about. The only danger is that the “space friend” has been little studied and all forecasts are made with an error.
Where will 2012 TC4 fall if it reaches Earth?- It’s too early to judge this. More accurate data will appear after astronomers study the composition of the asteroid.
At the moment, the date of the closest approach of asteroid 2012 TC4 to the Earth is October 12, 2017 at 5:41 UTC.
Let us recall that the last large-scale incident of a meteorite colliding with the Earth occurred on February 15, 2013 in Chelyabinsk. The famous “Chelyabinsk meteorite” thundered not only in Chelyabinsk, making it even more severe, but throughout the world.

Asteroid TC4 is flying towards Earth, the latest data: the collision on October 12, 2017, astronomer Judith Rus from the USA called inevitable. NASA scientists deny this.
The asteroid is flying towards Earth on October 12, 2017: in the event of a TC4 collision, a disaster will be inevitable - experts
Astronomer Judith Rees from the University of Texas claims that the size of the asteroid that will approach Earth on October 12, 2017 is 40 thousand kilometers, and its collision with our planet is almost inevitable.
As Politexpert writes with reference to a researcher, if an asteroid falls to Earth on October 12, 2017, our planet will face irreversible catastrophic changes. It is clarified that we are talking about the giant asteroid 2012 TC4, called Florence, which is twice the size idhumkz famous Chelyabinsk meteorite.
The exact distance at which 2012 TC4 will pass near the Earth is unknown, but experts from NASA and the European Space Agency say that the chances of the asteroid colliding with the planet on October 12 are almost zero.
According to Russian scientists, the minimum distance at which Florence will approach our planet will be 44.9 thousand kilometers, which is approximately 10 times less than the distance of the Moon from the Earth.
“The asteroid, with a diameter of about 40 meters, will fly past the Earth on October 12 at 7:42 Ural time. Compared to other TC4, it is very small, but it is the only one that will fly so close to the Earth,” the department of astronomy, geodesy and monitoring said in a statement environment Ural Federal University.
At the same time, Russian astronomers have denied rumors that have spread on the Internet that a giant asteroid will fall to Earth on October 12. According to experts, at the moment all potentially dangerous celestial bodies are known, and they are located at a fairly large distance from the Earth. Scientists have called on Russians to “filter” all predictions about the end of the world and treat them with skepticism, since in most cases such rumors are spread by those seeking popularity.
In turn, the leading engineer of Tomsk state university stated that the collision of large asteroids with the planet will be known long before the event.
As he wrote, the diameter of the Chelyabinsk meteorite was 19 meters. Its size was almost half the size of Florence, and it burned heavily in the atmosphere, but as a result of its fall, almost 1.5 thousand people were injured to one degree or another, and about 7 thousand buildings were damaged in the city.
Researchers warn that a huge space object could fall to earth this year. The Mirror writes about this.
According to the publication, a group of researchers discovered an object in space with a diameter of 40 meters, which is moving towards the Earth at high speed. According to their calculations, the collision of the “comic alien” with our planet will occur on October 12, 2017.
The fall of an object to the surface of the Earth will lead to catastrophic consequences. The publication reports that as a result of the collision, the ozone layer of our planet could be completely destroyed. This, in turn, will lead to climate change and the death of all life on the surface of the Earth.

The expert commented on the dangerous approach of asteroid 2012 TC4 to the Earth. The diameter of the object is 20-25 meters. The celestial body will pass at a distance of 40 thousand km from the center of the Earth. According to Skripnichenko, this object is almost 10 times larger than the Chelyabinsk meteorite.
“This phenomenon can be compared to the movement of the asteroid Duende. It was a 50-meter object. It was approaching on the same dates in 2013, when the Chelyabinsk meteorite fell. The phenomenon is curious from the point of view of celestial mechanics, since such close approaches are an extraordinary thing, the gravitational field of the earth can affect its orbit,” he noted.
The expert also noted that if an asteroid fell to Earth, the disaster could be much more serious. It is noted that the celestial body passes at a sufficient distance and the chance of approach can be estimated as one in several million.
“From a terminological point of view, this object cannot be called potentially dangerous, since it is small. On the other hand, it is interesting to track it, since it passes quite close,” Skripnichenko noted.
It is noted that after the Chelyabinsk event, there is talk at the level of the International Astronomical Union about the need to lower the bar for potentially dangerous objects. So, according to the expert, dangerous objects can be from 20 to 30 meters. Towards a consensus on this issue haven't arrived yet.
An asteroid flies towards Earth today 2017: collision October 12, 2017, end of the world. What is known today, whether it will fall or not, how to see where it will take place, the latest news.
The result of systematic observations by astronomers was the message that a space object with a significant diameter and enormous mass is approaching our planet. This is asteroid TC4. Astronomers' calculations show that on October 12, 2017, the distance between the cosmic body and the Earth will be minimal.
Astronomers noticed TC4 in 2012. Then for the first time he found himself in the field of view of powerful telescopes. Having calculated the orbit of this space object, scientists predicted that it will return to Earth in 2017. Time has shown that the astronomers' calculations were correct.
Where will asteroid 2017 hit?
Large cosmic bodies often approach our planet. Many fly by and do no harm to the Earth. But history also knows about the fall of large meteorites. Scientists associate climate change on the planet and the death of dinosaurs with the fall of a meteorite that occurred many millions of years ago. Explosion Tunguska meteorite destroyed a large area of forest. In Chelyabinsk, a meteorite fell on the city and caused serious damage to its infrastructure.

Where will the meteorite fall October 12, 2017
An asteroid with a diameter of 40 meters is approaching the Earth, which is twice the size of the Chelyabinsk meteorite.
Experts noticed the cosmic body back in 2012 and gave it the name 2012 TC4, writes Zvezda. The exact distance at which the asteroid will fly from Earth is still unknown.
It is noted that in the event of a collision of a celestial body with a planet, humanity will face a catastrophe. However, scientists assure that the likelihood of a “meeting” is extremely low.
Earlier, the portal iz.ru wrote that scientists from the American space agency NASA discovered a double asteroid that has signs of a comet. It is located in the asteroid belt between Mars and Jupiter.
