P\u0103m\u00e2ntul este o \u021bint\u0103 \u00een mi\u0219care \u00eentr-o galerie de tir. Aproape \u00een fiecare zi, un mic fragment de roc\u0103 spa\u021bial\u0103 trece la o distan\u021b\u0103 de c\u00e2teva milioane de kilometri de planet\u0103 \u2013 adesea f\u0103r\u0103 s\u0103 fie observat. Uneori se apropie mai mult dec\u00e2t Luna.<\/p>\n<\/div>\n

Oamenii de \u0219tiin\u021b\u0103 estimeaz\u0103 c\u0103 ar putea exista p\u00e2n\u0103 la 100 000 de asteroizi apropia\u021bi de P\u0103m\u00e2nt cu un diametru mai mare de 100 de metri \u2013 adic\u0103 de dimensiunea unui teren de fotbal. Au fost descoperi\u021bi peste 600 de asteroizi care trec la mic\u0103 distan\u021b\u0103 de P\u0103m\u00e2nt \u0219i au o dimensiune mai mare de 1 km. Mai sunt \u00eenc\u0103 sute care nu au fost \u00eenc\u0103 descoperi\u021bi.<\/p>\n

La fiecare c\u00e2teva mii de ani, un asteroid se va ciocni efectiv de P\u0103m\u00e2nt. Cel mai recent eveniment de acest fel a avut loc \u00een Siberia, \u00een 1908, c\u00e2nd un asteroid de dimensiuni reduse a distrus o suprafa\u021b\u0103 de peste 2000 de kilometri p\u0103tra\u021bi de p\u0103dure. Explozia ar fi putut distruge un ora\u0219 de dimensiunea Parisului sau a Londrei.<\/p>\n

Foarte rar, are loc un impact care distruge via\u021ba pe o mare parte a planetei. Acum 65 de milioane de ani, un asteroid cu diametrul de 10 kilometri a generat o explozie mai puternic\u0103 dec\u00e2t toate bombele cu hidrogen de pe P\u0103m\u00e2nt. Acesta a s\u0103pat un crater cu diametrul de 180 de kilometri \u00een Mexic \u0219i a \u00eempr\u0103\u0219tiat un strat de cenu\u0219\u0103 pe tot globul. Incendiile pe scar\u0103 larg\u0103, urmate de \u00eentuneric \u0219i frig extrem, au dus la dispari\u021bia dinozaurilor.<\/p>","protected":false},"excerpt":{"rendered":"
