"Asteroid Day is a growing global movement, supported by international organizations, experts in planetary science, astronauts and citizens around the world to increase awareness, education and support of programs for greater detection, knowledge of the composition, mapping and deflection of dangerous asteroids. ASTEROID DAY is held each year on JUNE 30, the anniversary of the largest asteroid impact of Earth in recent history, 1908 Tunguska event in Siberia, which devastated 2000 square km/800 square miles in Siberia. ASTEROID DAY was co-founded in 2014 by Astrophysicist and QUEEN lead musician Dr. Brian May and Filmmaker Grig Richters, Apollo 9 Astronaut Rusty Schweickart and Silicon Valley operative Danica Remy."
