Under the aegis of United Nation International Asteroid Day is celebrated every year on 30th June across the globe . International Asteroid Day aims to raise public awareness about the asteroid impact hazard and to inform the public about the crisis communication actions to be taken at the global level in case of a credible near-Earth object threat.

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."

What is Near-Earth objects :

Near-Earth objects (NEOs) represent potentially catastrophic threats to our planet. NEO is an asteroid or comet, which passes close to the Earth's orbit. According to NASA’s Center for NEO Studies, there are over 16 000 Near Earth Asteroids discovered. The Tunguska asteroid event in Siberia, Russian Federation, on 30 June 1908, was the Earth's largest asteroid impact in recorded history.
