Planetary Defense refers to the set of strategies, technologies, and efforts aimed at detecting, tracking, and mitigating the threat posed by near-Earth objects (NEOs), particularly asteroids and comets that could potentially collide with Earth. The primary goal of planetary defense is to prevent or minimize the impact of such celestial bodies, which could cause significant damage to the planet, including loss of life and environmental destruction. This field encompasses various scientific and engineering disciplines, including astronomy, physics, and aerospace engineering, and involves international collaboration for observational and preventive measures. Approaches to planetary defense include deflection techniques, such as kinetic impactors or gravitational tugs, as well as the development of early warning systems to detect NEOs well in advance of any potential impact.
The asteroid 2024 YR4 poses a 1.3% risk of collision with Earth, but experts emphasize that the odds are nearly 99% in our favor. With a size between 40 and…
