F\u00f6r miljontals \u00e5r sedan befann sig m\u00e5nen mycket n\u00e4rmare jorden och s\u00e5g st\u00f6rre ut p\u00e5 himlen. Den roterade ocks\u00e5 mycket snabbare. Gradvis saktade den ner. Idag fullbordar m\u00e5nen ett varv var 27:e dag, vilket \u00e4r samma tid som det tar att kretsa en g\u00e5ng runt jorden. Det inneb\u00e4r att vi alltid ser samma sida av m\u00e5nen. Den bortre sidan \u00e4r alltid dold f\u00f6r oss.<\/p>\n<\/div>\n

M\u00e5nen har inget eget ljus. Den lyser genom att reflektera solljus. Precis som jorden befinner sig h\u00e4lften av m\u00e5nen i dagsljus och h\u00e4lften i m\u00f6rker (natt). Ibland ser vi hela dagsidan \u2013 detta kallas \u2018fullm\u00e5ne\u2019.<\/p>\n

Ibland ser vi bara en smal, b\u00f6jd ljusstrimma, som kallas en \u2018m\u00e5nsk\u00e4ra\u2019. Ibland kan vi inte se m\u00e5nen alls, eftersom vi tittar p\u00e5 dess nattida. Detta kallas \u2018nym\u00e5ne\u2019.<\/p>\n

Sedan urminnes tider har m\u00e4nniskor observerat hur m\u00e5nen tycks byta form, fr\u00e5n en tunn halvm\u00e5ne till fullm\u00e5ne och tillbaka igen. Dessa \u2018faser\u2019 beror p\u00e5 att m\u00e5nen kretsar runt jorden en g\u00e5ng var 29\u00bd:e dag. Denna \u2018m\u00e5nad\u2019 har anv\u00e4nts f\u00f6r att m\u00e4ta tiden \u00f6ver hela v\u00e4rlden i tusentals \u00e5r.<\/p>","protected":false},"excerpt":{"rendered":"
