Scientists believe that the fall of a large asteroid to Earth is just a matter of time. Such events happened billions of years ago, and will happen billions of years from now.. So far we have been lucky, but, most likely, humanity will live to see the time when the fall of the “space stone” becomes inevitable.. And you need to be prepared for this, writes Science Alert.

Organizations around the world monitor the sky and map near-Earth objects. Larger stones are more dangerous, but they are also much rarer.. And scientists have reliable maps that show almost all known asteroids with a diameter of a kilometer or more.. This is important, because such stones can not only wipe out entire cities from the face of the Earth, but also cause serious environmental damage..

In order to assess the threat such asteroids pose, scientists decided to trace their trajectory in the next 1000 years.. And this analysis showed that none of the asteroids with a diameter of more than a kilometer in the next hundreds or 1000 years does not pose a danger to the Earth..

At the same time, it is difficult to predict the movement of " This is due to the fact that in orbital dynamics, even small changes over time can lead to serious consequences..

During the study, scientists identified one of the asteroids, (7482) 1994 PC1, as the most dangerous. In the next thousand years, it will often come close to our planet, but this does not mean that it will fall on it..

Another asteroid, 143651, is also of concern. Its orbit is so chaotic that it is difficult to predict its position over the next decades.. That is, it may or may not pose a threat, it is difficult to say for sure.

In total, astronomers have identified 28 candidates that have a non-zero probability of a "

Recall that on March 17, the asteroid 2023 EY flew at a distance of 240 thousand kilometers from Earth. That's about two-thirds of the distance from the Earth to the Moon..
