Mercur este prima planet\u0103 fa\u021b\u0103 de Soare. Nu este foarte u\u0219or de observat, deoarece pe cer se afl\u0103 \u00eentotdeauna aproape de Soare. Chiar \u0219i atunci c\u00e2nd se afl\u0103 \u00een cea mai favorabil\u0103 pozi\u021bie, este aproape de orizont \u0219i vizibil\u0103 doar c\u00e2teva ore dup\u0103 apusul Soarelui sau \u00eenainte de r\u0103s\u0103ritul Soarelui.<\/p>\n<\/div>\n

Numit\u0103 dup\u0103 mesagerul \u00eenaripat al zeilor, planeta se \u00eenv\u00e2rte \u00een jurul Soarelui o dat\u0103 la 88 de zile. Cu toate acestea, se rote\u0219te \u00een jurul propriului ax foarte \u00eencet \u2013 o dat\u0103 la 58,6 zile. Aceasta reprezint\u0103 exact dou\u0103 treimi din perioada sa orbital\u0103.<\/p>\n

Mercur este o planet\u0103 mic\u0103, st\u00e2ncoas\u0103. Are o l\u0103\u021bime aproximativ egal\u0103 cu cea a Oceanului Atlantic, iar 18 planete de dimensiunea lui Mercur ar \u00eenc\u0103pea \u00een interiorul P\u0103m\u00e2ntului.<\/p>\n

Mercur seam\u0103n\u0103 foarte mult cu Luna. Suprafa\u021ba sa este acoperit\u0103 de cratere de impact. Nu are atmosfer\u0103 \u0219i nici ap\u0103. Temperatura la amiaz\u0103 la ecuator poate ajunge p\u00e2n\u0103 la 450 \u00b0C, dar nop\u021bile sunt extrem de reci, cu temperaturi sub -180 \u00b0C. Este posibil s\u0103 existe ghea\u021b\u0103 de ap\u0103 \u00een craterele ad\u00e2nci \u0219i \u00eentunecate din apropierea polilor.<\/p>\n

Mercur are o densitate surprinz\u0103tor de mare. Se crede c\u0103 are un nucleu mare de fier care ocup\u0103 cea mai mare parte a interiorului planetei. De asemenea, are un c\u00e2mp magnetic surprinz\u0103tor de puternic.<\/p>\n

P\u00e2n\u0103 \u00een prezent, mai pu\u021bin de jum\u0103tate din suprafa\u021b\u0103 a fost fotografiat\u0103 de la distan\u021b\u0103 mic\u0103 de sonda spa\u021bial\u0103 Mariner 10. ESA \u0219i Japonia inten\u021bioneaz\u0103 s\u0103 trimit\u0103 dou\u0103 sonde orbitale c\u0103tre Mercur \u00een 2013. Misiunea BepiColombo poart\u0103 numele unui renumit matematician \u0219i om de \u0219tiin\u021b\u0103 italian.<\/p>","protected":false},"excerpt":{"rendered":"
