N\u00e4r den susar f\u00f6rbi jorden \u00e5r 2013 kommer en nyuppt\u00e4ckt asteroid att passera f\u00f6rbi v\u00e5r planet \u2013 men det blir inte mycket till marginal! Den 50 meter stora rymdstenen f\u00f6rv\u00e4ntas komma n\u00e4rmare \u00e4n m\u00e5nga av de satelliter som kretsar kring jorden, vilket p\u00e5minner oss om hur viktigt det \u00e4r att h\u00e5lla ett \u00f6ga p\u00e5 hoten fr\u00e5n rymden.<\/p>\n<\/div>\n

Ett amat\u00f6rteam uppt\u00e4ckte den ovanliga asteroiden, som fick namnet 2012 DA14, den 22 februari. P\u00e5 grund av dess ringa storlek och omloppsbana uppt\u00e4ckte de den f\u00f6rst efter att den hade passerat f\u00f6rbi jorden p\u00e5 ett avst\u00e5nd som motsvarade ungef\u00e4r sju g\u00e5nger avst\u00e5ndet till m\u00e5nen.<\/p>\n

Forskarna f\u00f6rutsp\u00e5r att den vid sin n\u00e4sta f\u00f6rbiflygning, som v\u00e4ntas \u00e4ga rum den 15 februari 2013, kommer att passera jorden p\u00e5 ett avst\u00e5nd av endast 24 000 km \u2013 n\u00e4rmare \u00e4n m\u00e5nga satelliter. \u201cDet \u00e4r ett s\u00e4kert avst\u00e5nd, men \u00e4nd\u00e5 tillr\u00e4ckligt n\u00e4ra f\u00f6r att asteroiden ska kunna ses med vanliga kikare\u201d, s\u00e4ger Detlef Koschny, som arbetar vid ESA:s avdelning f\u00f6r rymdl\u00e4gesbild (SSA).<\/p>\n

Asteroiden uppt\u00e4cktes av observatoriet La Sagra Sky Survey i syd\u00f6stra Spanien, som \u00e4r en av de m\u00f6rkaste platserna i Europa med minst ljusf\u00f6rorening.<\/p>\n

En kollision med jorden har uteslutits vid asteroidens n\u00e4sta bes\u00f6k, men den n\u00e4ra passagen kommer att hj\u00e4lpa astronomerna att f\u00f6rdjupa sina studier av detta \u00e4mne. Tillsammans med information om rymdv\u00e4der och rymdskrot kommer dessa uppgifter att hj\u00e4lpa europeiska forskare att f\u00f6rst\u00e5 och bed\u00f6ma riskerna, s\u00e4rskilt om man n\u00e5gonsin skulle uppt\u00e4cka en asteroid som hotar jorden.<\/p>","protected":false},"excerpt":{"rendered":"
