Today is the International Asteroid Day!
Asteroid Day as observed annually on 30 June is the United Nations sanctioned day of public awareness of the risks of asteroid impacts.
In December 2016 the United Nations General Assembly adopted resolution A/RES/71/90, declaring 30 June International Asteroid Day in order to "observe each year at the international level the anniversary of the Tunguska impact over Siberia, Russian Federation, on 30 June 1908, and to raise public awareness about the asteroid impact hazard."
