  • World Asteroid Day is observed on June 30 every year.


  • Asteroids are celestial rocks smaller than a planet but revolve around the sun like them. They are leftovers from the formation of our solar system. From being as small as 10 meters across to as huge as 530 km in diameter, asteroids have varied sizes.

World Asteroid Day


  • The United Nations has designated June 30 as World Asteroid Day.
  • The day marks the anniversary of the Tunguska asteroid impact which occurred over Siberia, Russian Federation, on June 30, 1908.
  • The UN General Assembly adopted the resolution based on the proposal made by the Association of Space Explorers, endorsed by the Committee on the Peaceful Uses of Outer Space (COPUOS).


  • The day aims to raise awareness about asteroid impact hazards and crisis communication actions in case of a credible asteroid threat to planet Earth.
  • The day aims to educate people about the latest and upcoming asteroid research and technology through numerous events and activities held by organizations across the globe.
  • The day also aims to encourage international efforts to identify and avert asteroid impacts for which astronauts, scientists, and public figures in 2015 signed the Asteroid Day Declaration. The declaration aims to condition and prepare people in charge for increased efforts to find and track asteroids and promotes development of plans to deflect or destroy asteroids that pose a threat.


  • World Asteroid Day is dedicated to preparing the planet for an asteroid impact.
  • Another goal for the day is to speed up the discovery of asteroids. Scientists think that only a small percentage of asteroids have been detected in space thus far, with hundreds more still to be discovered.
  • The idea is to raise awareness of, not only the dangers of asteroids, but also the fact that we have solutions in hand to find dangerous asteroids and do something about it.
