A F\u00f6ld olyan, mint egy mozg\u00f3 c\u00e9lpont egy l\u00f6v\u00f6ld\u00e9ben. Szinte minden nap egy kis \u0171rk\u0151darab halad el a bolyg\u00f3t\u00f3l n\u00e9h\u00e1ny milli\u00f3 kilom\u00e9terre \u2013 gyakran \u00e9szrev\u00e9tlen\u00fcl. N\u00e9ha m\u00e9g a Holdn\u00e1l is k\u00f6zelebb ker\u00fclnek hozz\u00e1.<\/p>\n<\/div>\n

A tud\u00f3sok \u00fagy v\u00e9lik, hogy ak\u00e1r 100 000 olyan F\u00f6ldk\u00f6zeli aszteroida is l\u00e9tezhet, amelyek \u00e1tm\u00e9r\u0151je meghaladja a 100 m\u00e9tert \u2013 ami egy futballp\u00e1lya m\u00e9ret\u00e9nek felel meg. T\u00f6bb mint 600, 1 km-n\u00e9l nagyobb, a F\u00f6ld mellett elsuhan\u00f3 aszteroid\u00e1t fedeztek fel eddig. T\u00f6bb sz\u00e1z tov\u00e1bbi p\u00e9ld\u00e1nyt m\u00e9g fel kell fedezni.<\/p>\n

N\u00e9h\u00e1ny ezer \u00e9vente val\u00f3ban becsap\u00f3dik egy aszteroida a F\u00f6ldbe. A legut\u00f3bbi ilyen esem\u00e9nyre 1908-ban Szib\u00e9ri\u00e1ban ker\u00fclt sor, amikor egy kis aszteroida t\u00f6bb mint 2000 n\u00e9gyzetkilom\u00e9ternyi erd\u0151t puszt\u00edtott el. A robban\u00e1s egy P\u00e1rizs vagy London m\u00e9ret\u0171 v\u00e1rost is elpuszt\u00edtott volna.<\/p>\n

Nagyon ritk\u00e1n fordul el\u0151 olyan becsap\u00f3d\u00e1s, amely a bolyg\u00f3 nagy r\u00e9sz\u00e9n kiirtja az \u00e9letet. 65 milli\u00f3 \u00e9vvel ezel\u0151tt egy 10 kilom\u00e9ter sz\u00e9les aszteroida olyan robban\u00e1st okozott, amely er\u0151sebb volt, mint a F\u00f6ld\u00f6n valaha felrobbantott \u00f6sszes hidrog\u00e9nbomba egy\u00fcttv\u00e9ve. Mexik\u00f3ban egy 180 kilom\u00e9ter sz\u00e9les kr\u00e1tert v\u00e1jt, \u00e9s hamur\u00e9teget bor\u00edtott az eg\u00e9sz vil\u00e1gra. A sz\u00e9les k\u00f6r\u0171 t\u00fczek, majd a s\u00f6t\u00e9ts\u00e9g \u00e9s a rendk\u00edv\u00fcli hideg a dinoszauruszok kihal\u00e1s\u00e1hoz vezettek.<\/p>","protected":false},"excerpt":{"rendered":"
