Wi\u0119kszo\u015b\u0107 asteroid jest tak ma\u0142a i znajduje si\u0119 tak daleko, \u017ce widzimy je jedynie jako male\u0144kie punkty \u015bwietlne. Wykrywa si\u0119 je na podstawie ich ruchu na tle \u2018gwiazd sta\u0142ych\u2019 na nocnym niebie. Wi\u0119cej informacji na ich temat uzyskujemy, badaj\u0105c \u015bwiat\u0142o, kt\u00f3re odbijaj\u0105, za pomoc\u0105 du\u017cych teleskop\u00f3w.<\/p>\n<\/div>\n

Jednak nawet Kosmiczny Teleskop Hubble\u2019a nie jest w stanie ujawni\u0107 o nich zbyt wielu informacji. Jedn\u0105 z najciekawszych asteroid jest bogata w metale Vesta. Zdj\u0119cia z teleskopu Hubble\u2019a pokazuj\u0105 do\u015b\u0107 okr\u0105g\u0142e cia\u0142o niebieskie z du\u017cym kraterem uderzeniowym.<\/p>\n

Niekt\u00f3re asteroidy przelatuj\u0105ce tu\u017c nad Ziemi\u0105 zosta\u0142y zbadane za pomoc\u0105 radaru. Echa radarowe s\u0105 rejestrowane przez du\u017ce radioteleskopy i wykorzystywane do okre\u015blenia ich kszta\u0142tu i rozmiar\u00f3w.<\/p>\n

Kilka asteroid zosta\u0142o dok\u0142adniej zbadanych przez sondy kosmiczne, kt\u00f3re do nich dotar\u0142y. Zdj\u0119cia przedstawiaj\u0105 obiekty pokryte licznymi kraterami, co \u015bwiadczy o tym, \u017ce przez miliardy lat by\u0142y one nara\u017cone na zderzenia. W 2000 roku sonda NEAR Shoemaker sta\u0142a si\u0119 pierwszym statkiem kosmicznym, kt\u00f3ry wszed\u0142 na orbit\u0119 wok\u00f3\u0142 asteroidy. Sonda zako\u0144czy\u0142a swoj\u0105 misj\u0119, dokonuj\u0105c historycznego l\u0105dowania na Erosie, jednej z najwi\u0119kszych asteroid bliskich Ziemi.<\/p>\n

Sonda kosmiczna \u201eRosetta\u201d nale\u017c\u0105ca do ESA przelecia\u0142a r\u00f3wnie\u017c obok dw\u00f3ch asteroid z pasa g\u0142\u00f3wnego \u2013 Steins i Lutetia \u2013 w drodze do komety. Lutetia, o \u015brednicy oko\u0142o 130 km, by\u0142a najwi\u0119ksz\u0105 asteroid\u0105, jak\u0105 dotychczas odwiedzi\u0142a sonda kosmiczna. ESA bada r\u00f3wnie\u017c sposoby na zmian\u0119 trajektorii lotu asteroidy zmierzaj\u0105cej w kierunku Ziemi.<\/p>","protected":false},"excerpt":{"rendered":"
