Scientists have discovered 30 thousand near-Earth asteroids: more than 1000 of them can collide with the Earth

According to the European Space Agency, there are many more such space rocks in the vicinity of our planet, but they are still worth finding.

Scientists from the European Space Agency (ESA) announced that 30,039 near-Earth asteroids. These are asteroids that revolve around the Sun and cross the Earth's orbit and therefore can pose a threat to our planet. Scientists believe that 1,425 of all near-Earth asteroids discovered so far may collide with the Earth, writes the Daily Mail.

The ESA statement says that to date, the existence of more than 30 thousand near-Earth asteroids and almost 1500 of them have already been confirmed in the solar system. they have a chance of falling to Earth. Therefore, all these space objects are under the close attention of scientists.

Most of the 30,000 of these asteroids have been discovered in the last 10 years, according to the ESA. This has become possible thanks to new technologies. But scientists believe that there are still many near-Earth asteroids flying in space that are waiting to be discovered.

“More than 50% of these 30,000 space rocks that fly near the Earth have been discovered by scientists since 2016. This indicates that our detection technologies are improving. We are confident that there are still many undiscovered near-Earth objects in the solar system. But new telescopes and new detection methods suggest it's only a matter of time before we find them,” says ESA's Richard Moissl.

According to scientists, of all the near-Earth asteroids discovered to date, 10 thousand stones have a diameter of more than 140 meters, and approximately 1,000 asteroids are more than 1 km in diameter. According to NASA classification, such asteroids pose a great danger to the Earth, because their fall can cause a real catastrophe. At the moment, 1,425 asteroids are potentially dangerous to the planet, according to scientists.

Near-Earth asteroids make up only a small fraction of all asteroids that have been discovered in the solar system. And there are more than 1 million of them. But given that many near-Earth asteroids have not yet been discovered, their number may be 10 times more than those known today. Most of the asteroids that are known to mankind revolve around the Sun in the asteroid belt, which is located between Mars and Jupiter.

The very first near-Earth asteroid that was discovered by astronomers is a rock called (433) Eros. It was discovered back in 1898 by the German scientist Carl Gustav Witt. This asteroid has an unusual shape and its diameter is approximately 17 km. The orbit of Eros is about 21 million km from Earth, which is 54 times farther than the distance of the Moon from our planet.

This asteroid is also notable for being the first space rock to which it flew to study spacecraft. This device, called NEAR Shoemaker, began to orbit Eros in 2000, and already landed on it in 2001.

Scientists classify asteroids as near-Earth if they orbit the Sun at a distance of 1.3 astronomical units (a.e.). 1 AU is the distance from our planet to the Sun, which is approximately 150 million km.

Scientists believe that any sufficiently large asteroid can pose a threat to the Earth. NASA calculated that on average every 5 thousand years an asteroid the size of a football field can fall to Earth, and every million years an asteroid that can destroy our civilization.
