Eksplodiral je v zraku nad obmo\u010djem imenovanim Tunguska v Sibiriji. Na sre\u010do je Tunguska zelo odro\u010dna, zato se domneva, da ni umrl nih\u010de. Vendar pa je bilo podrtih 80 milijonov dreves \u2013 kar pokriva obmo\u010dje, podobno po velikosti kot Veliki London! Tunguski dogodek je bil najve\u010dji udar, ki ga je Zemlja do\u017eivela v novej\u0161i zgodovini. V spomin na ta dogodek se 30. junij vsako leto praznuje kot Dan asteroidov.<\/p>\n<\/div>\n<p>Dan asteroidov je odli\u010dna prilo\u017enost, da razmislimo o teh kamnitih telesih v vesolju ter o tem, kako nam lahko pomagajo \u2013 in kako nam lahko \u0161kodujejo. Od leta 2009 ESA vodi prizadevanja za iskanje asteroidov in kometov, ki bi nam lahko predstavljali nevarnost. Ti se imenujejo objekti v bli\u017eini Zemlje ali skraj\u0161ano NEO, saj jih njihove orbite v vesolju pripeljejo blizu Zemlje, zato obstaja nevarnost, da bi pri\u0161lo do trka.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3004\" data-credit=\"Public domain \u2013 N.

ESA pomaga tudi pri povezovanju astronomov po vsem svetu v okviru programa \u00bbSpace Situational Awareness\u00ab, saj velja: ve\u010d o\u010di in teleskopov imamo za iskanje NEO-jev, bolje je!<\/p>\n<p>ESA razvija ukrepe za za\u0161\u010dito Zemlje v primeru, da bi se NEO resni\u010dno preve\u010d pribli\u017eal. Ta <a href=\"http:\/\/www.esa.int\/Our_Activities\/Space_Engineering_Technology\/Hera\" target=\"_blank\" rel=\"noopener\">Misija Hera<\/a>, ki naj bi se za\u010del izvajati leta 2023, bo opazoval asteroid Didymos, da bi ugotovil, kako se spremeni njegova smer, ko vanj tr\u010di sonda. To nam bo pokazalo, kako preusmeriti asteroide, ki so na trkovni poti proti Zemlji.<\/p>\n<p>Asteroidi niso vsi nevarni \u2013 lahko nam celo koristijo. To pa zato, ker vsebujejo snovi in surovine, ki jih bomo morda nekega dne lahko pridobili za uporabo tukaj na Zemlji ali pa nam bodo pomagale pri \u0161iritvi v vesolje. Asteroidi nam pomagajo tudi pri spoznavanju razmer v vesolju v davni preteklosti, ko je bilo Oson\u010dje \u0161e zelo mlado.<\/p>\n<p>Vsako leto se dogodki v okviru Dneva asteroidov prena\u0161ajo v \u017eivo po vsem svetu, program pa je poln raznovrstnih vsebin, ki zdru\u017eujejo astronavte, rock zvezde in znanstvenike. Razpravljalo se bo tudi o domiselnih na\u010dinih za odstranjevanje NEO-jev iz Zemljine orbite! Vsak dan asteroidov poteka na stotine dogodkov, doslej pa je 78 dr\u017eav gostilo koncerte, delavnice, predavanja in \u0161e mnogo ve\u010d.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1822\" data-credit=\"M.
