According to NASA, at the end of this week, on Saturday, August 10, at a speed of 16,772 kilometers per hour, a very large asteroid will approach our planet. Scientists say the 2006-named QQ23 is the size of a skyscraper. Its diameter is almost 600 meters. The media and the public are already worried. However, scientists say that there is no threat. An asteroid must fly past the earth at a safe distance. At any rate, current calculations prove this.
What are the sizes of an asteroid?
The exact dimensions of the system are 569 meters. It was discovered in 2006. By comparison, the height of the American skyscraper Empire State Building is 443 meters (with a tower).

According to experts Lindley Johnson and Kelly Fast of NASA's Planetary Defense Coordination Office, the distance between our planet and the asteroid at the nearest point should be about 7.5 million kilometers. Therefore nothing threatens the inhabitants of the planet. By comparison, the moon is 384,000 kilometers away, about 20 times closer.
Scientists say that they are tracking so-called "near-Earth objects," which include not only asteroids but also comets, as well as their fragments that revolve around the sun. By space standards, 8 million kilometers is really a very short distance to Earth. Scientists refer to such objects as near Earth.
What happens when an asteroid hits the earth?
According to NASA experts, at least 6 asteroids the size of 2006 QQ23 fly past our planet every year. When a 600-meter object falls on the ground, the consequences are catastrophic. Of course not global. But safe in the region. If such a stone falls into the water, it can come to huge tsunamis. The consequences for cities located in coastal areas within the fall radius of an object are unimaginable.

Currently, NASA scientists know that there are at least 900 near-Earth asteroids larger than one kilometer in our solar system. But the smaller cosmic paving stones on our planet are much bigger. The bill goes to millions. And that creates very big problems. Compact asteroids are much harder to spot.
For example, the European Space Agency recently reported that only a week earlier, an asteroid the size of a soccer field flew past the earth.

The distance between our planet and a small celestial body with a diameter of 100 meters was only 65,000 kilometers or 1/5 of the distance to the moon. Interestingly enough, they only found it when it was as close as possible to Earth and began to move away from it. Scientists of the European Space Agency (ESA) say that we are in urgent need of ground-based telescopes to effectively observe near-Earth objects of such small size.
