Astronomers at Johns Hopkins University have identified an effective and safe way to avoid a collision disaster if an asteroid approaches Earth.
The researchers examined what would happen if an asteroid with a diameter of 100 meters was detonated by a nuclear device, explaining in which case a celestial body could be prevented from falling to Earth, according to the newspaper “sciencedirect”.
Scientists have analyzed how different asteroids’ orbits and the different velocities distributions of fragments in which a celestial body can be fractured affect the fate of the scattered fragments.
A hypothetical case was revisited where the detonation took place a few meters from the surface of an asteroid similar to Asteroid, but five times less massive.
It turns out that if you blow up an asteroid two months before the collision, this will reduce the mass of the impact of a celestial body a thousand times or more, that is, 99.9% of the mass of the asteroid will not enter the Earth’s atmosphere.
For larger objects, the explosion would be slightly less effective, but if a celestial body was destroyed within six months, it would be possible to reduce the mass of the collision by 99%.
According to scientists, kinetic impact elements are best used to deflect the asteroid 10 months before the impact.
However, in emergency situations, when a dangerous asteroid is detected shortly before it hits Earth, more efficient and faster methods of disaster prevention are needed.
