266 asteroids are currently defined as having the potential to collide with Earth
An asteroid with a diameter of half a kilometer approached the Earth on Friday to the distance of "almost collision".
The asteroid passed the earth at a distance equal to 12 times the distance between us and the moon, a distance so small that the scientists of the American space agency, NASA, defined the event as "almost a collision". NASA personnel, who monitor asteroids and comets approaching the Earth, noted, however, that this time there was no real danger of impact.
And yet, the great proximity of the asteroid allowed researchers to get a better idea of the nature of the celestial body. Tracking of the approaching asteroid began on August 26, and was given the name QW7 2,000. It moved at high speed, and even excelled in extraordinary brightness; It could also be viewed with a large amateur telescope.
266 asteroids are currently defined as having the potential to collide with Earth, and all of them are constantly being tracked. They move through space in different trajectories, but not one of them is marked as an immediate threat to world peace. However, the scientists warn, the possibility of a giant asteroid hitting the Earth and wreaking considerable destruction exists all the time.

A perusal of sky and telescope news from 73 shows that this year a meteor of the type called a grating meteor passed tens of kilometers from the earth. It deserves its name because of its ability to almost "scratch" the earth. It passed over the Western Hemisphere at a speed of about 90 times the speed of sound, made a supersonic boom, was photographed by many people and its exact trajectory is calculated
With the help of his radar images picked up by spy satellites. If it was lower by a few kilometers, or alternatively if there was a slightly higher mountain in its path. The meteor could have caused a disaster on a large scale. Luckily for us, the meteor went as it came.
