Már csak egy napunk van hátra, óriási meteor közelít a Föld felé

Még a NASA is aggódik miatta.

Február 16-án egy méretét és pályáját tekintve is potenciálisan veszélyes aszteroida közelíti meg bolygónkat.

Az 199145 (2005 YY128) névre keresztelt űrszikla másodpercenként közel 25 ezer kilométert tesz meg a világűrben. Ezen a napon nagyjából 4,5 millió kilométerre lesz csak bolygónktól, ami csillagászati szempontból nem számít nagy távolságnak. Ám mivel keresztezi a Föld pályáját,

a potenciálisan veszélyes aszteroidák közé sorolja a NASA.

Ez az aszteroida az Apolló-család tagja, és átmérője nagyjából 0,5 és 1,3 km közé tehető.

Ezzel nagyobbnak számít, mint a hasonló objektumok nagyja (97%-a), mérete körülbelül a Golden Gate hídéval egyezik meg és 2,12 évente kerüli meg a Napot egy nagyon elliptikusnak mondható pályán – írja az Időkép a spacereference.org cikke alapján.
