Ziemia to ruchomy cel w strzelnicy. Niemal ka\u017cdego dnia niewielki fragment kosmicznej ska\u0142y przelatuje w odleg\u0142o\u015bci kilku milion\u00f3w kilometr\u00f3w od naszej planety \u2013 cz\u0119sto niezauwa\u017cony. Czasami zbli\u017caj\u0105 si\u0119 one nawet bli\u017cej ni\u017c Ksi\u0119\u017cyc.<\/p>\n<\/div>\n

Naukowcy szacuj\u0105, \u017ce mo\u017ce istnie\u0107 nawet 100 000 asteroid bliskich Ziemi o \u015brednicy przekraczaj\u0105cej 100 metr\u00f3w \u2013 czyli wielko\u015bci boiska pi\u0142karskiego. Odkryto ponad 600 obiekt\u00f3w przelatuj\u0105cych w pobli\u017cu Ziemi, kt\u00f3rych \u015brednica przekracza 1 km. Setki kolejnych wci\u0105\u017c pozostaj\u0105 do odkrycia.<\/p>\n

Co kilka tysi\u0119cy lat jaka\u015b asteroida faktycznie uderza w nasz\u0105 planet\u0119. Ostatnie takie zdarzenie mia\u0142o miejsce na Syberii w 1908 roku, kiedy to niewielka asteroida zr\u00f3wna\u0142a z ziemi\u0105 ponad 2000 kilometr\u00f3w kwadratowych lasu. Wybuch ten zniszczy\u0142by miasto wielko\u015bci Pary\u017ca lub Londynu.<\/p>\n

Bardzo rzadko dochodzi do zderzenia, kt\u00f3re unicestwia \u017cycie na znacznej cz\u0119\u015bci planety. 65 milion\u00f3w lat temu asteroida o \u015brednicy 10 kilometr\u00f3w wywo\u0142a\u0142a eksplozj\u0119 pot\u0119\u017cniejsz\u0105 ni\u017c wszystkie bomby wodorowe na Ziemi. W Meksyku utworzy\u0142a krater o szeroko\u015bci 180 kilometr\u00f3w, a warstwa popio\u0142u pokry\u0142a ca\u0142\u0105 planet\u0119. Rozleg\u0142e po\u017cary, po kt\u00f3rych nast\u0105pi\u0142a ciemno\u015b\u0107 i ekstremalne zimno, doprowadzi\u0142y do wygini\u0119cia dinozaur\u00f3w.<\/p>","protected":false},"excerpt":{"rendered":"
