International Asteroid Day FAQs
When is International Asteroid Day?
International Asteroid Day 2026 falls on Tuesday, June 30, a day dedicated to global awareness about asteroid impacts and planetary defense.
How many asteroids are there in our solar system?
There are estimated to be over one million asteroids in our solar system, with the vast majority residing in the main asteroid belt between Mars and Jupiter. Scientists have only discovered a small fraction of these objects, especially those that could potentially pose a threat to Earth.
What is the goal of the 100X Asteroid Declaration?
The 100X Asteroid Declaration, created by Asteroid Day founders and scientists, aims to dramatically increase the rate of asteroid discovery. The goal is to identify 100,000 new asteroids per year within a decade, significantly improving our ability to track and understand potential threats.
Why was June 30 chosen for International Asteroid Day?
June 30 was chosen to commemorate the anniversary of the 1908 Tunguska event, the largest asteroid impact in recorded history. This event, which flattened 2,000 square kilometers of forest in Siberia, serves as a powerful reminder of the potential destructive power of asteroids.
International Asteroid Day Activities
Organize an event in your community
If there isn’t already an Asteroid Day event taking place in your area, consider organizing one of your own. The holiday is often celebrated with activities like lectures, discussions, and concerts. Hosting your own could be a great benefit to your community. It’s also a fantastic way to do your part to help raise awareness, and to meet like-minded members of your community who share your interest in asteroids.
Watch 51 Degrees North
Check out the film that started it all, but be prepared to experience a rush of emotions. The movie is fictional, but it’s an exploration of a potential real-world scenario, and it gives you a lot to think about. It’s a great motivator to learn more about asteroids and how to stay safe in the event of an impact.
Volunteer for Asteroid Day’s organizers
The holiday’s creators and organizers are in need of volunteers to help them make worldwide Asteroid Day events run smoothly. More than 700 events are expected to take place this year, and volunteers can help to set up events, create content, design graphics, and help spread the word.
Why We Love International Asteroid Day
It raises awareness
Most people are understandably so focused on what’s happening here on earth that they have no idea that asteroids pose a threat to our safety. International Asteroid Day is a great way to combat the lack of awareness around the issue. In the event that an asteroid does strike the earth, the holiday and the movement surrounding it may make a major difference in preparing people to protect themselves.
It encourages space exploration
International Asteroid Day inspires everyday people to hit the books and learn more about the sky above them, and the galaxy surrounding us. Among established scientists, the holiday creates an incentive for further research and perhaps even an increase in scientific funding. The United Nations General Assembly has now officially recognized the holiday, which will lead to that much more encouragement for research. Cheers to shaping bright minds!
It brings people together over a common cause
Humans are more alike than we are different, and nothing makes that more clear than a shared threat that could harm the whole planet if it were to strike. Protecting ourselves against asteroids is a much more effective effort if the world’s greatest minds band together to share ideas.
