P\u0159ed miliony let byl M\u011bs\u00edc na obloze mnohem bl\u00ed\u017e a v\u011bt\u0161\u00ed. Tak\u00e9 se ot\u00e1\u010del mnohem rychleji. Postupn\u011b se jeho rotace zpomalila. Dnes M\u011bs\u00edc vykon\u00e1 jednu ot\u00e1\u010dku za 27 dn\u00ed, co\u017e je stejn\u00e1 doba, jakou mu trv\u00e1 jeden ob\u011bh kolem Zem\u011b. To znamen\u00e1, \u017ee v\u017edy vid\u00edme stejnou stranu M\u011bs\u00edce. Odvr\u00e1cen\u00e1 strana je n\u00e1m v\u017edy skryt\u00e1.<\/p>\n<\/div>\n

M\u011bs\u00edc nem\u00e1 vlastn\u00ed sv\u011btlo. Sv\u00edt\u00ed t\u00edm, \u017ee odr\u00e1\u017e\u00ed slune\u010dn\u00ed sv\u011btlo. Stejn\u011b jako Zem\u011b je i M\u011bs\u00edc z poloviny osv\u011btlen\u00fd a z poloviny pono\u0159en\u00fd do tmy (noci). N\u011bkdy vid\u00edme celou denn\u00ed stranu \u2013 tomuto jevu se \u0159\u00edk\u00e1 \u2018\u00fapln\u011bk\u2019.<\/p>\n

N\u011bkdy vid\u00edme jen \u00fazk\u00fd zak\u0159iven\u00fd pruh sv\u011btla, kter\u00fd se naz\u00fdv\u00e1 \u2018srpek\u2019. N\u011bkdy M\u011bs\u00edc nevid\u00edme v\u016fbec, proto\u017ee se d\u00edv\u00e1me na jeho no\u010dn\u00ed stranu. To je \u2018nov\u00fd M\u011bs\u00edc\u2019.<\/p>\n

Od nejstar\u0161\u00edch dob lid\u00e9 pozoruj\u00ed, jak se zd\u00e1nliv\u00fd tvar M\u011bs\u00edce m\u011bn\u00ed od tenk\u00e9ho srpku a\u017e po \u00fapln\u011bk a zase zp\u011bt.
