Solutions to prevent the asteroid stabbing into the Earth

The risk of a planet that is capable of destroying the whole city crashed into the earth in less than 8 years is very small. But even if this asteroid rushes, humanity can defend such a threat, according to experts. NASA on February 18 announced the recent possibility of a planet detected on the earth on December 22, 2032, increased by 3.1%, the risk of collision with the highest meteorite in modern forecasts. However, Richard Moissl, Head of Planet’s Defense Department at the European Space Agency, said we have some ways to change or destroy the asteroid like 2024 YR4, according to AFP.

Launching spacecraft crashed into a planet

This is the only planetary tactic that has been tested with real planet. In 2022, NASA’s double planet redirects the spacecraft stabbing the spacecraft into a 160 -m wide Dimorphos, transforming its trajectory around a larger meteorite. The advantage of this plan is that we can stab many spacecraft into the asteroid 2024 YR4, observe how each train changes its flight route, according to Bruce Betts, scientific director of the non -benefited organization. Planetary Society.

The planet discovered last December was estimated at 40 – 90 m wide, about half of the dimorphos size. Moissl warns to be careful not to create too strong collisions. If the spacecraft destroys a part of the asteroid, it can cause the stone pieces to shoot towards the Earth. If the event changes the collision area on Earth, for example from Paris to Moscow, that will certainly cause serious problems.

Using tug ship, ion beam, paint

Another idea called an attractive tug ship includes the use of a large spacecraft near the asteroid and the use of gravity to push it away from the Earth without direct contact. The same plan is to use aircraft near the asteroid, equipped with a push engine to emit regular ion beams that make the object fly. The scientists also consider spraying blank on one side of the asteroid, increasing reflexes, thereby slowly changing its flight route.

Use nuclear bombs

We can also explode a planet with a nuclear bomb. Instead of burying nuclear weapons deep inside the asteroid as in the 1998 science fiction film, this tactic is likely to include a nearby bomb. Last year, American researchers tested hypotheses with a large a planet in the laboratory and discovered X -rays from the nuclear explosion that will evaporate its surface, causing it to fly in the opposite direction. again. Even if you ignore ethical, political and legal issues when launching nuclear weapons into the universe, this is the last option for a wide planet of kilometers like meteorites to erase dinosaurs. In addition, there is still a risk of a nuclear explosion that can cause some external fragments to work towards the Earth.

Laser

The researchers also proposed the idea of ​​shooting laser beams from the spacecraft to evaporate the side of the planet and push it away. Experiments show this plan feasible, but not one of the top techniques for consideration.

The asteroid shift is “the feasible, but depends on the speed of the planet’s motion”, according to Moissl. If all defensive solutions fail, researchers can predict the planet’s collision area, it is likely that it can threaten a city. That means to prepare for the collision and evacuation of the residential area is the last measure. Moissl emphasized that about 97% of the asteroid 2024 YR4 did not hit the Earth.
