Co-founded by Stephen Hawking, Queen guitarist and astrophysicist Brian May and other former astronauts and technologists with the sanction of the United Nations, International Asteroid Day is an annual observance meant to promote awareness about the minor planets of the inner Solar System and the threats that these near-Earth objects can pose for cataclysm and ways to mitigate the vulnerability through close monitoring. 30 June was chosen as the date as it marks the anniversary of the 1908 Tunguska Event in the Eastern Siberia Taiga, an estimated twelve megaton explosion that flattened two thousand square kilometers of forest caused by the air burst of a meteoroid, devastating for local wildlife but spared greater catastrophe by dint of the region being sparsely populated by humans.
