Nov\u00fd asteroid je pro na\u0161i planetu potencion\u00e1ln\u011b nebezpe\u010dn\u00fd.<\/strong><\/p>\n

Dr\u00e1ha jeho pohybu se podob\u00e1 Enckeov\u011b komet\u011b, kter\u00e1 mo\u017en\u00e1 zrodila \u201etunguzsk\u00fd meteorit\u201c.<\/p>\n

29. dubna 2009 skupina americk\u00fdch astronom\u016f z observato\u0159e Catalina (st\u00e1t Arizona), objevila velmi podivn\u00fd objekt. Asteroid, podle p\u0159edb\u011b\u017en\u00fdch m\u011b\u0159en\u00ed, m\u00e1 pr\u016fm\u011br kolem 2 \u2013 3 km, a pohybuje se v opa\u010dn\u00e9m sm\u011bru ne\u017e v\u011bt\u0161ina objekt\u016f ve Slune\u010dn\u00ed soustav\u011b. Nav\u00edc se ale pohybuje pod velmi velk\u00fdm \u00fahlem k rovin\u011b pohybu Zem\u011b \u2013 a d\u00edky tomu nemohl b\u00fdt tak dlouho objeven.<\/p>\n

Odkud se berou takov\u00e9 asteroidy v\u011bdci nejsou schopni vysv\u011btlit. Existuje p\u0159edpoklad, \u017ee zm\u011bnily sv\u016fj sm\u011br pohybu pod vlivem p\u0159ita\u017elivosti velk\u00fdch planet \u2013 Jupitera nebo Saturnu.<\/p>\n

Dosud bylo takov\u00fdch asteroid\u016f objeveno asi 20. Tento nov\u00fd, nazvan\u00fd 2009\u041d\u042182 se pohybuje k Zemi nejbl\u00ed\u017ee ze v\u0161ech. I kdy\u017e vzd\u00e1lenost od Zem\u011b je kolem 3,5 mili\u00f3nu kilometr\u016f, je pro Zemi potenci\u00e1ln\u011b nebezpe\u010dn\u00fd. Pokud by je\u0161t\u011b jednou zm\u011bnil sm\u011br pohybu, let\u011bl by p\u0159\u00edmo na n\u00e1s.<\/p>\n

V nejbli\u017e\u0161\u00edch letech se k n\u00e1m maxim\u00e1ln\u011b p\u0159ibl\u00ed\u017e\u00ed v lednu roku 2012.<\/p>\n

Asteroid p\u0159ekvapil je\u0161t\u011b jedn\u00edm faktem \u2013 trasa pohybu 2009\u041d\u042182 se podob\u00e1 dr\u00e1ze, jakou se pohybuje Enckeova kometa. P\u0159esto se za n\u00edm net\u00e1hne \u017e\u00e1dn\u00fd chvost, tak\u017ee nen\u00ed \u017e\u00e1dn\u00fd d\u016fvod se domn\u00edvat, \u017ee by byl jedn\u00edm z jej\u00edch \u00falomk\u016f. V\u011bdce to zaujalo proto, proto\u017ee st\u00e1le plat\u00ed p\u0159edpoklad, \u017ee tzv. tunguzsk\u00fd meteorit byl jedn\u00edm z fragment\u016f t\u00e9to komety. Zat\u00edm n\u00e1s v\u0161ak tento asteroid ni\u010d\u00edm neohro\u017euje.<\/p>\n

2009 HC82 (v azbuce chybn\u011b zaps\u00e1no jako 2009\u041d\u042182) je bl\u00edzkozemn\u00ed asteroid, kter\u00fd je v\u00fdznamn\u00fd p\u0159edev\u0161\u00edm svou neobvyklou ob\u011b\u017enou dr\u00e1hou.
