A Merk\u00far a Naphoz legk\u00f6zelebb es\u0151 bolyg\u00f3. Megfigyel\u00e9se nem t\u00fal egyszer\u0171, mivel az \u00e9gen mindig a Nap k\u00f6zel\u00e9ben tal\u00e1lhat\u00f3. M\u00e9g a legkedvez\u0151bb helyzetben is a horizont k\u00f6zel\u00e9ben van, \u00e9s csak napnyugta ut\u00e1n vagy napkelte el\u0151tt n\u00e9h\u00e1ny \u00f3r\u00e1ra l\u00e1that\u00f3.<\/p>\n<\/div>\n

Az istenek sz\u00e1rnyas h\u00edrn\u00f6k\u00e9r\u0151l elnevezett bolyg\u00f3 88 naponta ker\u00fcli meg a Napot. Saj\u00e1t tengelye k\u00f6r\u00fcl azonban nagyon lassan forog \u2013 58,6 naponta egyszer. Ez pontosan a kering\u00e9si idej\u00e9nek k\u00e9tharmada.<\/p>\n

A Merk\u00far egy kicsi, szikl\u00e1s bolyg\u00f3. \u00c1tm\u00e9r\u0151je nagyj\u00e1b\u00f3l akkora, mint az Atlanti-\u00f3ce\u00e1n\u00e9, \u00e9s 18 Merk\u00far elf\u00e9rne a F\u00f6ld belsej\u00e9ben.<\/p>\n

A Merk\u00far nagyon hasonl\u00edt a Holdra. Felsz\u00edn\u00e9t becsap\u00f3d\u00e1si kr\u00e1terek bor\u00edtj\u00e1k. Nincs l\u00e9gk\u00f6re \u00e9s nincs rajta v\u00edz. Az egyenl\u00edt\u0151n a d\u00e9li h\u0151m\u00e9rs\u00e9klet ak\u00e1r 450 \u00b0C-ra is emelkedhet, az \u00e9jszak\u00e1k viszont rendk\u00edv\u00fcl hidegek, -180 \u00b0C alatt. A sarkok k\u00f6zel\u00e9ben tal\u00e1lhat\u00f3 m\u00e9ly, s\u00f6t\u00e9t kr\u00e1terekben el\u0151fordulhat n\u00e9mi v\u00edzj\u00e9g.<\/p>\n

A Merk\u00far meglep\u0151en s\u0171r\u0171. \u00dagy gondolj\u00e1k, hogy hatalmas vasmagja van, amely a Merk\u00far belsej\u00e9nek nagy r\u00e9sz\u00e9t kit\u00f6lti. Ezenk\u00edv\u00fcl meglep\u0151en er\u0151s m\u00e1gneses mez\u0151je is van.<\/p>\n

Eddig a Mariner 10 \u0171rszonda a felsz\u00edn kevesebb mint fel\u00e9t f\u00e9nyk\u00e9pezte le k\u00f6zelr\u0151l. Az ESA \u00e9s Jap\u00e1n 2013-ban k\u00e9t kering\u0151 \u0171rszond\u00e1t tervez a Merk\u00farra k\u00fcldeni. A BepiColombo-misszi\u00f3 egy h\u00edres olasz matematikusr\u00f3l \u00e9s tud\u00f3sr\u00f3l kapta a nev\u00e9t.<\/p>","protected":false},"excerpt":{"rendered":"
