We will have a symposium on planetary defense (spaceguard). The main theme of this symposium is the issue of celestial bodies colliding with the Earth, and we would like to hold a wide-ranging discussion and exchange of information on the discovery, tracking, physical observation and exploration of near-Earth objects (NEOs), celestial body collisions, Earth collision avoidance, and societal responses. In particular, ESA's Hera was launched in this year, and there has been growing interest in the asteroid Apophis, which will approach Earth in 2029. We hope that many of you who are interested will participate.

*This symposium will be held in collaboration with "The 16th Spaceguard Symposium" by the Japan Spaceguard Association.
