Asteroid Day is a United Nations proclaimed global educational awareness movement held annually on 30 June, the anniversary of the 1908 Siberian Tunguska asteroid event. Asteroid Day events are hosted worldwide by independent organisations including schools, museums, space agencies and clubs, who seek to educate their communities about the threats and opportunities of asteroids. The Asteroid Day website, social media, newsletters and events are produced by Luxembourg based charity Asteroid Foundation. Asteroid Day was co-founded in 2014 by Dr. Brian May, astrophysicist and lead guitarist of Queen, with Danica Remy, President of B612 Foundation, Rusty Schweickart, Apollo 9 Astronaut, and filmmaker Grig Richters.
