About Asteroid Day
Asteroid Day is an annual global movement to increase public awareness of potential asteroid impacts with Earth, and the importance of guarding against them. It was co-founded in 2015 by Brian May, astrophysicist and lead guitarist for the rock band Queen, Apollo astronaut Rusty Schweickart, and German filmmaker Grig Richters.
The Day is held on 30 June each year to mark Earth’s largest asteroid impact in recorded history, the Siberia Tunguska event, which devastated over 2000 sq km, the equivalent area of a major metropolitan city.
In 2015, for the inaugural Asteroid Day, partners organised more than 150 events worldwide, spreading the word to millions of people.
Activities included lectures, films, expert science presentations and educational workshops, variously organised by museums, research institutes, government agencies, universities, astronomers, filmmakers and concerned citizens, coming together to recognise our collective responsibility to address asteroid impacts, the only natural disaster humankind can prevent through increased awareness and education.
