Will an asteroid fall to Earth this fall?

Since June of this year, the entire Internet is literally boilingnews that this fall on Earth may fall asteroid size from 20 to 50 meters. The fall of such a celestial body on a global scale certainly will not cause significant problems, but in a local one, for example, having fallen on a city, such a stone is capable of causing many troubles. I hope everyone remembers what happened in the Chelyabinsk region in 2013?

The asteroid called 2006 QV89 wasIt was discovered by astronomers 13 years ago, in the summer of 2006, when it got close to Earth at a distance of several million kilometers. Watching him for 10 days, scientists were able to calculate the trajectory of its movement. It was established that it belongs to asteroids, which from time to time intersect the orbit of the Earth. Then it turned out that on September 9, 2019, he should approach the planet again, and the chances of a collision were estimated, according to various sources, as 1 to 7000. If we talk in percentage terms, this is approximately 0.00014%. In other words, the probability is there, but it is very low.

Nevertheless, this did not stop the media from raising a fuss about the topic of an asteroid falling to Earth.

As we wrote earlier, small asteroidsa few meters in size it is very difficult to detect at a great distance just by looking at the whole sky. But if you know the trajectory of the object in advance, then you can monitor certain narrow areas of outer space, where it can theoretically be at the time of observation.

Asteroid 2006 QV89 motion path

The trajectory of the object 2006 QV89 scientistswell known. Therefore, in early July, they calculated the areas in which QV89 could theoretically be at the moment. For a more thorough search, the experts used a very powerful telescope VLT (Very Large Telescope), which is located in Chile. According to the researchers, the VLT resolution would have made it possible to see even smaller objects, but they did not find any traces of asteroid 2006 QV89. Among the explanatory assumptions - an asteroid could change the trajectory of its movement.

All this allowed scientists to reconsider the future trajectory of the asteroid and completely deprive it of any chance of a collision with the Earth.

In short, you can quietly exhale. No collision of the asteroid with the Earth this fall can be expected. But for fans of panic, we have another news. In 2022, the asteroid 2009JF1 approaches the Earth. Chances of his collision with our planet are estimated as 1 to 4464. Wait for new headlines in the media.

The most dangerous asteroid

According to the American Space AgencyNASA, Bennu is the most dangerous asteroid for Earth. The space block has a diameter of about 550 meters. According to rough estimates, the probability of a collision of this asteroid with the Earth is 1 to 4000. If it really falls on our planet, the energy released when the body falls to the surface will be equivalent in power to an atomic bomb of 2700 megatons.

Projected dates of convergence with our planetBennu asteroid - 2169 and 2199 years. Now the object is being studied using the OSIRIS-REx spacecraft. He recently reached a closest approach to the object. More information about this can be found in our material.
