International Asteroid Day in 2023

Friday, 30 Jun

Days to go:

International Asteroid Day is a global observance aimed at raising awareness about asteroids, their potential impact on Earth, and the importance of studying and monitoring these celestial objects. This annual event emphasizes the need to develop human understanding of asteroids, while also enhancing space science and technology to address potential collisions. The day serves as an opportunity for communities worldwide, including New Zealand, to discuss and share information, providing crucial insight into how to prevent harmful asteroid impacts.

The roots of International Asteroid Day date back to 2014, when a group of renowned scientists, astronauts, and artists declared the official observance. The primary motivation was the Tunguska event of 1908 – the largest asteroid impact in recorded history – which devastated a vast area of Siberian forest. For New Zealand, where the skies are often clear and free of light pollution, this day holds particular significance. Having unique access to the southern sky, New Zealanders possess a special opportunity to observe asteroids, engage with experts, and participate in skywatching events – all of which contribute to global scientific cooperation and the protection of our planet.

Astrophotography workshops, telescope viewings, and informative talks are held on International Asteriod Day, giving attendees the chance to familiarize themselves with the southern sky and understand the importance of studying and monitoring asteroids. By participating in these activities, New Zealanders not only strengthen global awareness of potential asteroid threats but also generate excitement and appreciation for the endless marvels of the cosmos. International Asteroid Day is observed annually on June 30th.
