M\u011bs\u00edce jsou p\u0159\u00edrodn\u00ed t\u011blesa, kter\u00e1 ob\u00edhaj\u00ed kolem planet. V\u011bdci je obvykle ozna\u010duj\u00ed jako planet\u00e1rn\u00ed satelity (satelity vytvo\u0159en\u00e9 \u010dlov\u011bkem se n\u011bkdy naz\u00fdvaj\u00ed um\u011bl\u00e9 m\u011bs\u00edce).

M\u011bs\u00edc Zem\u011b je ve srovn\u00e1n\u00ed s planetou neobvykle velk\u00fd. V\u011bt\u0161ina m\u011bs\u00edc\u016f je ve srovn\u00e1n\u00ed se svou mate\u0159skou planetou nepatrn\u00e1. N\u011bkter\u00e9 m\u011bs\u00edce Jupitera a Saturnu jsou v\u0161ak mnohem v\u011bt\u0161\u00ed ne\u017e n\u00e1\u0161 M\u011bs\u00edc.

Vzhledem ke sv\u00e9 mal\u00e9 velikosti nejsou t\u00e9m\u011b\u0159 \u017e\u00e1dn\u00e9 m\u011bs\u00edce schopny udr\u017eet si atmosf\u00e9ru. Jejich slab\u00e1 gravitace umo\u017e\u0148uje plyn\u016fm unikat do vesm\u00edru. V\u00fdjimkou je Titan, nejv\u011bt\u0161\u00ed m\u011bs\u00edc v Saturnov\u011b soustav\u011b. Titan m\u00e1 hust\u0161\u00ed a siln\u011bj\u0161\u00ed atmosf\u00e9ru ne\u017e Zem\u011b. Hlavn\u00edm plynem v atmosf\u00e9\u0159e obou planet je dus\u00edk, ale na Titanu nen\u00ed kysl\u00edk ani \u017eivot. Jeho povrch zakr\u00fdv\u00e1 oran\u017eov\u00fd opar. N\u011bkte\u0159\u00ed v\u011bdci pova\u017euj\u00ed Titan za primitivn\u00ed Zemi v hlubok\u00e9m zmrazen\u00ed.<\/p>\n
