Asteroid deflection is a field of research focused on developing technologies and methods to prevent potentially hazardous asteroids from colliding with Earth. This can involve redirecting the trajectory of an asteroid using various techniques such as spacecraft missions, gravitational forces, or nuclear detonations. The goal of asteroid deflection research is to mitigate the potential catastrophic consequences of an asteroid impact by identifying and implementing effective deflection strategies. This field is of particular importance due to the potential threat that large asteroids pose to life on Earth.
