Jorden er et bevegelig m\u00e5l i en skytebane. Nesten hver dag passerer en liten bit romstein forbi planeten i en avstand p\u00e5 noen f\u00e5 millioner kilometer \u2013 ofte uten at vi legger merke til det. Noen ganger kommer de n\u00e6rmere enn M\u00e5nen.<\/p>\n<\/div>\n

Forskere mener at det kan finnes s\u00e5 mange som 100 000 asteroider i n\u00e6rheten av Jorden som er over 100 meter i diameter \u2013 p\u00e5 st\u00f8rrelse med en fotballbane. Over 600 asteroider som passerer tett forbi Jorden og er st\u00f8rre enn 1 km, er blitt oppdaget. Det gjenst\u00e5r fortsatt \u00e5 finne hundrevis flere.<\/p>\n

Hvert par tusen \u00e5r vil en asteroide faktisk treffe jorden. Den siste hendelsen fant sted i Sibir i 1908, da en liten asteroide jevnet mer enn 2000 kvadratkilometer skog med jorden. Eksplosjonen ville ha utslettet en by p\u00e5 st\u00f8rrelse med Paris eller London.<\/p>\n

Sv\u00e6rt sjelden skjer det et nedslag som utrydder alt liv over store deler av planeten. For 65 millioner \u00e5r siden for\u00e5rsaket en asteroide p\u00e5 10 kilometer i diameter en eksplosjon som var kraftigere enn alle hydrogenbomber p\u00e5 Jorden til sammen. Den gravde ut et krater p\u00e5 180 kilometer i diameter i Mexico og spredte et lag med aske over hele verden. Omfattende branner, etterfulgt av m\u00f8rke og ekstrem kulde, f\u00f8rte til at dinosaurene d\u00f8de ut.<\/p>","protected":false},"excerpt":{"rendered":"
