For millioner av \u00e5r siden var M\u00e5nen mye n\u00e6rmere og st\u00f8rre p\u00e5 himmelen. Den roterte ogs\u00e5 mye raskere. Etter hvert ble rotasjonen langsommere. I dag fullf\u00f8rer m\u00e5nen en omdreining hver 27. dag, det samme som det tar \u00e5 g\u00e5 \u00e9n gang rundt jorden. Dette betyr at vi alltid ser den samme siden av m\u00e5nen. Baksiden er alltid skjult for oss.<\/p>\n<\/div>\n

M\u00e5nen har ikke noe eget lys. Den lyser ved \u00e5 reflektere sollys. I likhet med Jorden er halvparten av M\u00e5nen i dagslys og halvparten i m\u00f8rke (natt). Noen ganger ser vi hele dagsiden \u2013 dette kalles \u2018fullm\u00e5ne\u2019.<\/p>\n

Noen ganger ser vi bare et smalt, buet lysb\u00e5nd, som kalles en \u2018halvm\u00e5ne\u2019. Noen ganger kan vi ikke se m\u00e5nen i det hele tatt, fordi vi ser p\u00e5 nattiden hennes. Dette er \u2018nym\u00e5nen\u2019.<\/p>\n

Helt siden urtiden har mennesker sett hvordan m\u00e5nen tilsynelatende skifter form, fra en tynn halvm\u00e5ne til fullm\u00e5ne og tilbake igjen. Disse \u2018fasene\u2019 skyldes at m\u00e5nen kretser rundt jorden \u00e9n gang hver 29\u00bd. dag. Denne \u2018m\u00e5neden\u2019 har blitt brukt til \u00e5 m\u00e5le tid over hele verden i tusenvis av \u00e5r.<\/p>","protected":false},"excerpt":{"rendered":"
