International Asteroid Day 2023: Date, Significance and History

In December 2016, the United Nations General Assembly passed a resolution (A/RES/71/90) establishing June 30th as International Asteroid Day. The purpose of this day is to annually commemorate the Tunguska impact that occurred in Siberia, Russian Federation, on June 30, 1908. Additionally, the day aims to raise public awareness about the potential hazards posed by asteroid impacts and educate people about the global crisis communication measures to be taken in the event of a credible near-Earth object threat.

This decision by the General Assembly was based on a proposal put forth by the Association of Space Explorers and received endorsement from the Committee on the Peaceful Uses of Outer Space (COPUOS).

Significance of World Asteroid Day

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.

As per the UN website, The International Asteroid Warning Network (IAWN) employs well-defined communication strategies and procedures to help governments analyse potential asteroid impacts and plan mitigating responses. The Space Mission Planning Advisory Group (SMPAG) is an inter-space agency group that analyses technologies required for near-Earth Object deflection and seeks consensus on planetary defence ideas.

History of International Asteroid Day

Near-Earth objects (NEOs) are asteroids or comets that come close to Earth’s orbit and pose potential catastrophic threats to our planet. NASA’s Center for NEO Studies has discovered over 16,000 Near Earth Asteroids. The Tunguska event in Siberia, Russia, on June 30, 1908, remains the largest recorded asteroid impact in Earth’s history.

On February 15, 2013, a significant fireball known as a “superbolide” entered Earth’s atmosphere and disintegrated over Chelyabinsk, Russia. According to NASA, the estimated diameter of the asteroid was approximately 18 meters with a mass of 11,000 tons. The impact energy of the Chelyabinsk Fireball was estimated to be around 440 kilotons of TNT explosives, making it the most energetic impact event since the Tunguska blast in 1908.

Recognizing the global nature of the NEO impact hazard, the United Nations Office for Outer Space Affairs (UNOOSA) has been actively involved in addressing this issue for many years. Cooperation among the international community is essential to identify NEOs that pose a threat and plan appropriate mitigation campaigns to ensure public safety.

To respond effectively to the NEO impact threat, the Committee on the Peaceful Uses of Outer Space (COPUOS) endorsed recommendations in 2013. This led to the establishment of two initiatives in 2014: the International Asteroid Warning Network (IAWN) and the Space Mission Planning Advisory Group (SMPAG).

The International Asteroid Warning Network (IAWN) employs well-defined communication plans and protocols to assist governments in analyzing the potential consequences of an asteroid impact and supports the planning of mitigation responses.

The Space Mission Planning Advisory Group (SMPAG) is an inter-agency forum that identifies the necessary technologies for deflecting near-Earth objects. It aims to build consensus on recommendations for measures to defend the planet from potential NEO threats.
