Planetary Defense Coordination Office

The Planetary Defense Coordination Office (PDCO) is a NASA agency responsible for detecting, tracking, and characterizing near-Earth objects (NEOs) like asteroids and comets that could pose a threat to Earth. It coordinates efforts among government agencies, scientists, and international partners to identify potential hazards early and develop strategies to mitigate impact risks. The goal is to protect our planet by providing timely warnings and exploring possible deflection or evacuation plans if a dangerous object is identified. Essentially, PDCO works to ensure Earth’s safety from celestial threats through monitoring and proactive planning.
