DESCRIPTION:\n	(A/RES/71/90)\n\n\n\n	In December 2016 the United Nations
	 General Assembly adopted resolution A/RES/71/90\, declaring 30 June Inter
	national Asteroid Day in order to \"observe each year at the international
	 level the anniversary of the Tunguska impact over Siberia\, Russian Feder
	ation\, on 30 June 1908\, and to raise public awareness about the asteroid
	 impact hazard.\"\n\n\n\n	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 o
	f a credible near-Earth object threat.\n\n\n\n	The General Assembly’s de
	cision was made based on a proposal by the Association of Space Explorers\
	, which was endorsed by the Committee on the Peaceful Uses of Outer Space 
	(COPUOS).\n\n\n\n	Background\n\n	Near-Earth objects (NEOs) represent poten
	tially catastrophic threats to our planet. NEO is an asteroid or comet\, w
	hich passes close to the Earth's orbit. According to NASA’s Center for N
	EO Studies\, there are over 16 000 Near Earth Asteroids discovered. The Tu
	nguska asteroid event in Siberia\, Russian Federation\, on 30 June 1908\, 
	was the Earth's largest asteroid impact in recorded history.\n\n\n\n	On 15
	 February 2013\, a large fireball (technically\, called a \"super bolide\"
	)\, traveling at a velocity of 18.6 kilometers per second\, entered the at
	mosphere and disintegrated in the skies over Chelyabinsk. According to NAS
	A\, the approximate effective diameter of the asteroid was estimated at 18
	 meters and its mass at 11\,000 tons. The approximate total impact energy 
	of the Chelyabinsk Fireball\, in kilotons of TNT explosives (the energy pa
	rameter usually quoted for a fireball)\, was 440 kilotons. The Chelyabinsk
	 event was an extraordinarily large fireball\, the most energetic impact e
	vent recognized since the 1908 Tunguska blast in Russian Siberia.\n\n\n\n	
	The United Nations Office for Outer Space Affairs (UNOOSA) has worked on N
	EOs for many years\, recognizing a NEO impact hazard as a global issue dem
	anding an international response. Addressing such a hazard\, including the
	 identification of those objects that pose a threat of impact and planning
	 a corresponding mitigation campaign\, requires cooperative action in the 
	interest of public safety on the part of the global community.\n\n\n\n	Bui
	lding on recommendations for an international response to a near-Earth Obj
	ect impact threat\, endorsed by the Committee on the Peaceful Uses of Oute
	r Space (COPUOS) in 2013\, the International Asteroid Warning Network (IAW
	N) and the Space Mission Planning Advisory Group (SMPAG) were established 
	in 2014.\n\n\n\n	The International Asteroid Warning Network (IAWN) uses we
	ll-defined communication plans and protocols to assist Governments in the 
	analysis of possible consequences of an asteroid impact and to support the
	 planning of mitigation responses.\n\n\n\n	The Space Mission Planning Advi
	sory Group (SMPAG) is an inter-space agency forum that identifies technolo
	gies needed for near-Earth Object deflection\, and aims to build consensus
	 on recommendations for planetary defense measures.\n\n
