Ksi\u0119\u017cyce to naturalne obiekty kr\u0105\u017c\u0105ce wok\u00f3\u0142 planet. Naukowcy zazwyczaj nazywaj\u0105 je satelitami planetarnymi (satelity stworzone przez cz\u0142owieka nazywane s\u0105 czasem sztucznymi ksi\u0119\u017cycami). W naszym Uk\u0142adzie S\u0142onecznym znajduje si\u0119 oko\u0142o 170 ksi\u0119\u017cyc\u00f3w. Wi\u0119kszo\u015b\u0107 z nich kr\u0105\u017cy wok\u00f3\u0142 gazowych gigant\u00f3w \u2013 Jowisza i Saturna. Ma\u0142e planety maj\u0105 zazwyczaj niewiele ksi\u0119\u017cyc\u00f3w: Mars ma dwa, Ziemia ma jeden, natomiast Wenus i Merkury nie maj\u0105 \u017cadnego.<\/p>\n<\/div>\n

Ksi\u0119\u017cyc Ziemi jest niezwykle du\u017cy w por\u00f3wnaniu z nasz\u0105 planet\u0105. Wi\u0119kszo\u015b\u0107 ksi\u0119\u017cyc\u00f3w jest znacznie mniejsza od otaczaj\u0105cej je planety. Jednak niekt\u00f3re ksi\u0119\u017cyce Jowisza i Saturna s\u0105 znacznie wi\u0119ksze od naszego Ksi\u0119\u017cyca. Ganimedes i Tytan s\u0105 wi\u0119ksze od Merkurego.<\/p>\n

Ze wzgl\u0119du na niewielkie rozmiary prawie wszystkie ksi\u0119\u017cyce nie s\u0105 w stanie utrzyma\u0107 atmosfery. Ich s\u0142aba grawitacja pozwala gazom ucieka\u0107 w przestrze\u0144 kosmiczn\u0105. Wyj\u0105tkiem jest Tytan, najwi\u0119kszy ksi\u0119\u017cyc w uk\u0142adzie Saturna. Tytan ma g\u0119stsz\u0105 i bardziej zwart\u0105 atmosfer\u0119 ni\u017c Ziemia. Azot jest g\u0142\u00f3wnym gazem w atmosferach obu cia\u0142 niebieskich, ale na Tytanie nie ma tlenu ani \u017cycia. Jego powierzchnia jest zas\u0142oni\u0119ta pomara\u0144czow\u0105 mgie\u0142k\u0105. Niekt\u00f3rzy naukowcy uwa\u017caj\u0105 Tytana za prymitywn\u0105 Ziemi\u0119 w stanie g\u0142\u0119bokiego zamro\u017cenia.<\/p>\n

Uwa\u017ca si\u0119, \u017ce niekt\u00f3re satelity, w tym nasz Ksi\u0119\u017cyc, powsta\u0142y w wyniku pot\u0119\u017cnych zderze\u0144 we wczesnej fazie historii Uk\u0142adu S\u0142onecznego. Ksi\u0119\u017cyc uformowa\u0142 si\u0119 z chmury od\u0142amk\u00f3w, kt\u00f3ra pozosta\u0142a na orbicie wok\u00f3\u0142 Ziemi. Inne mog\u0142y powsta\u0107 z chmury gazu i py\u0142u otaczaj\u0105cej planety olbrzymie w czasie, gdy przyci\u0105ga\u0142y one do siebie materi\u0119. Wi\u0119kszo\u015b\u0107 mniejszych ksi\u0119\u017cyc\u00f3w to komety lub asteroidy, kt\u00f3re zosta\u0142y przechwycone, gdy przelecia\u0142y zbyt blisko du\u017cej planety.<\/p>","protected":false},"excerpt":{"rendered":"
