This week, asteroid observers on Earth have their hands full, five potentially dangerous rocks are crossing our planet. The largest of them, "2010 PK9", has an estimated diameter of 260 meters and will pbad on Earth Friday afternoon at a speed of nearly 60 000 km / h.

Asteroid: Are you afraid of Armageddon?
But we do not need to be afraid of a strike this time around. Calculated at cosmic scales, the safety distance of about three million kilometers to "2010 PK9" is small, but more than enough for our safety. This is at least eight times the distance from the moon to the earth.
Another asteroid will approach us this Wednesday, without which most of the inhabitants of the Earth will notice it. "2019 OD" pbaded on its orbit even in the orbit of the moon.
NASA now monitors hundreds of such objects close to the Earth. On the website of the Center for Near-Earth Objects Research (CNEOS), all known tracks are recorded. We can see that we do not have to worry about most known asteroids.
The asteroid "Apophis" could soon hit the ground
However, only the most. On Friday, April 13, 2029, it will be rare. According to the latest calculations, the bullet "99942 Apophis" from 300 to 680 meters missing only a stellar hair width of about 38 000 kilometers.
If it actually hit our planet, an explosive force of over 900 megatonnes of TNT would be released. But for the Apocalypse, that's not enough, thank God. The impact would still be enormous: just 250 kilometers from the crater on the mainland, you have a one in two chance of surviving. If the Apophis hit an ocean, tidal waves over 100 meters high would cause coastal flooding.
(Currently) but no reason for sleepless nights. NASA has promised – if that were to happen, to warn the population before the end of the world.
