National Preparedness Strategy & Action Plan for Near-Earth Object Hazards and Planetary Defense

By United States. White House Office

From the document: "Near-Earth Objects (NEOs) are asteroids and comets that orbit the Sun but have orbits that can bring them into Earth's neighborhood--within 30 million miles of Earth's orbit. Planetary defense encompasses all the capabilities needed to detect and warn of potential 10-meter and larger NEO impacts with Earth, and to either prevent such an event or mitigate the possible effects of an impact. This 'National Preparedness Strategy and Action Plan for Near-Earth Object Hazards and Planetary Defense' (2023 Planetary Defense Strategy) updates the United States' first comprehensive Near-Earth Object Preparedness Strategy and Action Plan, released in 2018. The 2023 Planetary Defense Strategy builds on existing efforts by Federal Departments and Agencies to address the hazard of NEO impacts, includes evaluation of where progress has been made since 2018, and focuses future work on planetary defense across the U.S. government."
