Like its closest neighbors, the solar system is literally filled with asteroids. Most of these objects will never intersect with us, but some of them will actually or will pose a threat to our planet in the future. The asteroid Chiksulub, for example, experienced a real “doomsday” on Earth 65 million years ago and destroyed dinosaurs and other animals. In an article published in the journal Astronomy & Astrophysics, researchers report an artificial neural network that identified several asteroids that may be dangerous to the earth. It is predicted that these eleven asteroids will collide with our planet after 2131. According to the study's authors, time is a very important resource in finding a way to prevent the asteroid from falling on our only home.
The incredible successes of AI
An artificial neural network developed by scientists from the University of Leiden (Netherlands) was able to identify up to 11 new asteroids that are considered dangerous and could collide with our planet after 2131. A neural network called HOI (Hazardous Object Identifier), which means “Hello” in Dutch, can predict the trajectory of asteroids no matter how far away they are today. The researchers modeled the orbits of the sun and planets for the next 10,000 years. Then they turned the clock back to see what was happening on this regressive orbit, including the asteroids identified so far and their orbital distribution.

Thanks to the newly created asteroid library, the neural network received information about all existing asteroids. Therefore, the neural network analyzed the trajectories of 2,000 asteroids previously identified by NASA to determine whether an asteroid was likely to fall to Earth in the near future.
As the authors of the study write, when you turn back the clock, you can see that many well-known asteroids have fallen to Earth. This is how you can create a library of orbits of asteroids that have ever fallen on the surface of our planet. The artificial intelligence system has selected 11 asteroids that were not previously classified as dangerous by NASA. In addition, these objects were not registered as potentially problematic. However, the diameter of each of them is more than 100 meters, and the mass is sufficient to create a catastrophic explosive force. Sooner or later, these spacewalkers could collide with our planet. Although the likelihood of them falling to Earth is very small or zero, these asteroids will come more than ten times closer to us than the moon in the period from 2131 to 2923.

Why haven't dangerous asteroids been discovered before?
The fact that 11 asteroids have not yet been identified as potentially dangerous is that the orbit of these objects is chaotic. As a result, they are not considered by current space agency software. In the future, the researchers want to improve the system in order to be able to predict dangerous areas with much greater accuracy. According to the New York Post, the work made it clear that the technology used was working. However, more information is needed to improve the results. The main problem is that interruptions in the orbit calculation can lead to important changes.
