A recent estimate suggests that asteroid 2024 YR4 has a 3.1% chance of hitting Earth on December 22, 2032, making it one of the most likely asteroid threats in modern times. However, experts say the world is better equipped to defend itself against such a threat.
The European Space Agency’s (ESA) planetary defense office estimates that even if an asteroid were to collide with Earth, it could be deflected using various methods. These include sending spacecraft to hit or disrupt the asteroid, flying alongside it to use gravitational force, and even painting one side of the asteroid white to change its trajectory.
Experts also consider non-contact methods, such as ejecting a continuous flow of atoms from a spacecraft, and contact methods like shooting laser beams to destroy an asteroid. However, some experts warn that these methods carry significant risks and should be used with caution.
Despite the rising odds, scientists say there is still about a 97% chance the asteroid will miss Earth. The world may not have time to prepare for such a threat, but having early warnings and defense strategies in place can minimize the impact of an asteroid collision.
The European Space Agency’s planetary defense office has been working on developing new methods to defend against asteroid threats like 2024 YR4. Experts stress that it is essential to remain vigilant and continue monitoring asteroid activity to ensure humanity’s safety.
