Outline
If a small solar system body such as an asteroid or comet were to collide with the Earth, it could cause a huge natural disaster. The activity of trying to prevent such disasters is called planetary defense, and in recent years, this activity has become very active internationally.At present, more than 36,000 celestial bodies approaching the Earth have been discovered, and probes have been sent to about 10 of these near-Earth objects. Experiments have also been conducted to change the orbits of asteroids. A group has been established under the United Nations to discuss celestial collisions, and international conferences and outreach activities are also being held frequently. In this session, we will introduce the latest situation regarding planetary defense, and then discuss what kind of response should be taken to this issue.
