7 years to go: a huge asteroid is hurtling towards Earth - NASA is preparing to nuke it.

Asteroid YR4 with a diameter of ~60 meters with a probability of 0.28% will hit the Earth, and with a probability of 4% will hit the Moon.

In both cases, the explosion will be 2000 times more powerful than Hiroshima if YR4 hits the Earth. And if it crashes into the Moon, there will be a huge release of dust particles that will destroy all satellites, telescopes and stations with astronauts - the Earth will get even in this case.

It should be taken into account that asteroids are absolutely unpredictable, so the chances of disaster at any moment can increase.

They want to destroy the asteroid with a nuclear charge in 2029-2031.
