Planetary Defense Strategies

Planetary defense strategies aim to detect and prevent potential asteroid or comet impacts that could threaten Earth. Key methods include tracking space objects to assess collision risks; deflecting or redirecting dangerous objects using techniques like nudging them with spacecraft or explosion; and, if necessary, evacuating or preparing regions at risk. Early detection is crucial, giving enough time to act and reduce impact threats. These strategies involve international cooperation and advanced technology to protect our planet from extraterrestrial hazards efficiently and safely.
