What is International Asteroid Day?

International Asteroid Day (celebrated annually on June 30th) is a global holiday first co-founded by prominent scientists and other interested parties and recognized by the United Nations in 2016.  Its primary goal is to raise awareness and public support for efforts to study asteroids and design impact prevention strategies.  Organizers selected June 30th in remembrance of the Siberian Tugunska event, a 1908 meteroid explosion in Russia's Eastern Siberian Taiga which caused damage across 830 square miles.  The Tugunska event was the largest impact event in recorded history.
