"🦖The dinosaurs didn’t have a space program." | NASA Planetary Defense

June 30 is Asteroid Day—an annual global awareness campaign established to educate the public about asteroids and the potential hazards they pose to Earth. 

Asteroid Day was co-founded in 2014 by astrophysicist Brian May, filmmaker Grigorij Richters, NASA astronaut Russel Schweickart, and Danica Remy of the B612 Foundation, following the Chelyabinsk meteor event in 2013. The United Nations officially recognized Asteroid Day in 2016, designating June 30 as the international observance to commemorate the Tunguska event of 1908, when a meteor airburst flattened over 2,150 km² of Siberian forest 

NASA’s Planetary Defense Program finds and tracks potentially hazardous asteroids and tests methods to keep us safe on Earth. This International Asteroid Day, learn more about our planetary defenders:
