One of the scientists who participated in the study said that although the number of rocky fields increases, the probability of an atherode attack destroying mankind is extremely low.

After studying the data collected by NASA, scientists have determined that "at least three times more" asteroids strike our planet today than when dinosaurs roamed on Earth, reported The Daily Star.

As Dr. Thomas Gernon, an Associate Professor of Earth Sciences at the University of Southampton who participated in the study, revealed that the researchers had come to this conclusion by studying the surface of the moon, which, as he said, "is our closest neighbor, so he gets hits the same asteroid population. "

According to him, the cosmic rocks that descend to the ground usually come from the asteroid belt, where collisions with asteroids "generate many fragments that over time can be directed to the ground."

Over time, these stones are bombarded by sunlight and there is a process that re-emits this energy and essentially gives these fragments a small button that can then send them down the road. "There's a lot of material coming out of the asteroid belt," said Dr. Gernon.

He noted, however, that the probability of striking an asteroid destroying mankind is extremely low, to put it mildly.

"There is no need for people to worry about this increased flow," he said, "that the big asteroid strikes – more than 1 kilometer – went from one in every 3-5 million years, 90 million years ago, to roughly 1-2 in every million years. , explained the scientist.
