Planetary defense is a field of space science focused on protecting Earth from potential impacts by asteroids and comets. This interdisciplinary endeavor involves detecting, tracking, and characterizing Near-Earth Objects (NEOs) to assess collision risks and develop strategies to mitigate these threats. Techniques for deflecting or disrupting an incoming NEO before it can impact Earth include kinetic impactors, gravity tractors, and nuclear devices, depending on the object’s size, composition, and trajectory. Collaborative efforts among global space agencies, such as NASA’s Planetary Defense Coordination Office and the European Space Agency’s NEO Coordination Centre, are crucial for sharing data, coordinating response strategies, and conducting simulation exercises to enhance preparedness. The continuous monitoring and research in planetary defense aim to ensure that if a threatening NEO is identified, humanity is ready to respond effectively to prevent a catastrophic event.
