International Asteroid Day, 30 June 2025

International Asteroid Day 2025 highlights the growing capabilities of planetary defense against asteroid threats. With advanced systems now tracking over 36,000 near-Earth objects and deflection technologies like NASA’s successful DART mission, we are better equipped than ever to detect and mitigate potential impacts. As we prepare for Apophis’ close approach in 2029, this global awareness day emphasizes the importance of international cooperation and public participation in safeguarding our planet.

On International Asteroid Day, we highlight cutting-edge research and innovative planetary defense initiatives that protect Earth from cosmic threats. We invite you to explore our curated resources on asteroid detection, deflection technologies, and global preparedness efforts. Together, we can advance our collective mission to defend our planet from near-Earth objects and build a more secure future for all.

Keynote Speakers:

Dr. Marco Fenucci Earth Object Coordination Centre, Italy	Dr. Josep Maria Trigo Rodriguez Institute of Space Sciences, Spain
