Merkur je prvi planet od Sonca. Opazovati ga ni ravno enostavno, saj je na nebu vedno blizu Sonca. Tudi ko je v najbolj ugodnem polo\u017eaju, je blizu obzorja in viden le nekaj ur po son\u010dnem zahodu ali pred son\u010dnim vzhodom.<\/p>\n<\/div>\n

Planet, poimenovan po krilatem bo\u017ejem glasniku, obkro\u017ei Sonce enkrat na 88 dni. Vendar se okoli svoje osi vrti zelo po\u010dasi \u2013 enkrat na 58,6 dni. To je natanko dve tretjini njegovega orbitalnega obdobja.<\/p>\n

Merkur je majhen, kamnit svet. Njegova \u0161irina je pribli\u017eno enaka \u0161irini Atlantskega oceana, v Zemljo pa bi se zmestilo 18 Merkurjev.<\/p>\n

Merkur je zelo podoben Luni. Njegova povr\u0161ina je prekrita z udarnimi kraterji. Nima atmosfere niti vode. Temperatura opoldne na ekvatorju lahko dose\u017ee 450 \u00b0C, no\u010di pa so izjemno mrzle, s temperaturami pod -180 \u00b0C. V globokih, temnih kraterjih blizu polov morda obstaja nekaj vodnega ledu.<\/p>\n

Merkur je presenetljivo gost. Domneva se, da ima veliko \u017eelezno jedro, ki zapolnjuje ve\u010dino notranjosti Merkurja. Ima tudi presenetljivo mo\u010dno magnetno polje.<\/p>\n

Doslej je vesoljska sonda Mariner 10 iz bli\u017eine posnela manj kot polovico povr\u0161ine. ESA in Japonska nameravata leta 2013 na Merkur poslati dve vesoljski sondi v orbito. Misija BepiColombo je poimenovana po znanem italijanskem matematiku in znanstveniku.<\/p>","protected":false},"excerpt":{"rendered":"
