Asteroid Day is a global awareness campaign where people from around the world come together to learn about asteroids and what we can do to protect our planet, families, communities, and future generations from future asteroid impacts. Asteroid Day is held each year on June 30, the anniversary of the largest impact in recent history, the 1908 Tunguska event in Siberia.

 Host an Event

All around the globe, regionally organised events are held on Asteroid Day. These events range from live concerts and community events, to lectures and other educational programmes, to raise public awareness of the need for increased detection and mapping of asteroids.
