N\u00e5r den suser forbi Jorden i 2013, vil en nyopdaget asteroide g\u00e5 forbi vores planet \u2013 men kun med en h\u00e5rsbredde! Den 50 m store rumsten forventes at komme t\u00e6ttere p\u00e5 Jorden end mange af de satellitter, der kredser om Jorden, hvilket minder os om, hvor vigtigt det er at holde \u00f8je med farer fra rummet.<\/p>\n<\/div>\n

Et amat\u00f8rteam opdagede den us\u00e6dvanlige asteroide, der fik navnet 2012 DA14, den 22. februar. P\u00e5 grund af dens lille st\u00f8rrelse og bane opdagede de den f\u00f8rst, efter at den var fl\u00f8jet forbi Jorden i en afstand, der svarede til cirka syv gange afstanden til M\u00e5nen.<\/p>\n

Forskere forudsiger, at den ved sin n\u00e6ste forbiflyvning, der forventes den 15. februar 2013, vil passere Jorden i en afstand p\u00e5 blot 24 000 km \u2013 t\u00e6ttere end mange satellitter. \u201cDet er en sikker afstand, men den er stadig t\u00e6t nok til, at asteroiden kan ses med almindelige kikkerter,\u201d siger Detlef Koschny, der arbejder i ESA\u2019s afdeling for rumoverv\u00e5gning (SSA).<\/p>\n

Asteroiden blev opdaget af La Sagra Sky Survey-observatoriet i det syd\u00f8stlige Spanien, som er et af de m\u00f8rkeste steder i Europa med mindst lysforurening.<\/p>\n

Det er udelukket, at asteroiden vil kollidere med Jorden ved sit n\u00e6ste bes\u00f8g, men den t\u00e6tte passage vil hj\u00e6lpe astronomerne med at unders\u00f8ge dette emne n\u00e6rmere. Sammen med oplysninger om rumvejr og rumskrot vil disse data hj\u00e6lpe europ\u00e6iske forskere med at forst\u00e5 og vurdere risici, is\u00e6r hvis der nogensinde bliver fundet en asteroide, der udg\u00f8r en trussel mod Jorden.<\/p>","protected":false},"excerpt":{"rendered":"
