摘要

Abstract: Near-Earth Asteroids (NEA) impose potential major disaster to humanity. Planetary defense is an inevitable requirement for the survival of human civilization. In recent years, China has made rapid progress in planetary defense research, which has won the attention of the government and attracted more and more scholars and organizations. This paper summarizes the research progress in planetary defense in China in recent years, including the fireball events in China, academic activities and policy planning, monitoring and warning technology, on-orbit defense technology, impact hazard assessment, international cooperation and science popularization.
