T\u00e4na \u00f6\u00f6sel v\u00f5ivad k\u00f5ik veidi rahulikumalt magada. Viimased vaatlused suure, Maad napilt m\u00f6\u00f6duva kosmosekivi \u2013 tuntud kui asteroid 2011 AG5 \u2013 kohta viitavad sellele, et see lendab 2040. aastal ohutult meie planeedist m\u00f6\u00f6da.<\/p>\n<\/div>\n

65 miljonit aastat tagasi h\u00e4vitas asteroidi kokkup\u00f5rge dinosaurused. Need k\u00fclmaverelised roomajad ei suutnud aga ehitada seadmeid, millega oleks saanud j\u00e4lgida tuhandeid kosmilisi kive, mis Maale l\u00e4henesid. Ilma eelneva hoiatuseta ei saanud nad midagi teha, et v\u00e4ljasuremist v\u00e4ltida.<\/p>\n

\u00d5nneks v\u00f5imaldab t\u00e4nap\u00e4evane tehnoloogia meil j\u00e4lgida l\u00e4henevaid objekte, mis v\u00f5ivad meie olemasolu ohustada. 2011. aasta jaanuaris avastati objekt 2011 AG5 Arizonas asuva spetsiaalse teleskoobi abil, mis otsib Maale l\u00e4hedal asuvaid objekte. Seej\u00e4rel j\u00e4lgisid mitmed observatooriumid seda 140 meetri laiust asteroidi \u00fcheksa kuu jooksul, enne kui see liiga kaugele eemaldus ja muutus liiga n\u00f5rgaks, et seda n\u00e4ha.<\/p>\n

Asteroidi 2011 AG5 orbiit ja asukoht seisuga 15. juuni 2012<\/figcaption><\/figure>\n

Vaatlused on olnud piiratud, kuna asteroid asub praegu Marsi orbiidist v\u00e4ljaspool ja p\u00e4evasel taevas P\u00e4ikese tagak\u00fcljel. 2013. aasta s\u00fcgisel paranevad tingimused aga niiv\u00f5rd, et nii kosmoses kui ka maapinnal asuvad teleskoobid saavad selle trajektoori paremini j\u00e4lgida. Sel ajal asub 2011 AG5 Maast 147 miljoni kilomeetri kaugusel, kuid on hilis\u00f5htusel taevas vaatlemiseks soodsas asukohas.<\/p>\n

Praegu k\u00e4ttesaadav teave viitab sellele, et on olemas v\u00e4ga v\u00e4ike v\u00f5imalus, et see v\u00f5ib 2040. aastal Maaga kokku p\u00f5rkuda. Siiski on eksperdid kogu maailmast, sealhulgas ESA, veendunud, et tulevased kosmosest ja maapinnalt tehtavad vaatlused v\u00e4hendavad seda t\u00f5en\u00e4osust peaaegu nullini. Isegi kui t\u00f5en\u00e4osus peaks suurenema, on ikkagi piisavalt aega, et planeerida ja l\u00e4bi viia missioon asteroidi trajektoori muutmiseks.<\/p>","protected":false},"excerpt":{"rendered":"
