International Asteroid Day History

The International Asteroid Day is a global awareness observance that aims to educate and inspire people to know more about asteroids, their part in the formation of the universe, and how they can be useful. The observance was founded by the astrophysicist Dr. Brian May. In 2016, the asteroid day was officially observed by the United Nations. The observance occurs annually on June 30th. This date was chosen because it marks the anniversary of the Tunguska Impact in 1908.
