Iplanethi eziseduze Sun lethiwa emuva ezikhathini zasendulo. Iphephandaba iThe Mercury unkulunkulu wamaRoma, nomvikeli abahambi nohwebo. Kanye isithunywa imikhumbi ezinezinyawo wonkulunkulu. Kungenxa ukunyakaza ngokushesha emazulwini iplanethi eziseduze Sun - njengoba kuba umzimba esheshayo esibhakabhakeni yethu - lethiwa.
izitatimende eyisisekelo
Iplanethi kakhudlwana Sun kunomhlaba cishe ezintathu izikhathi. ukusondela Mercury ukuze inkanyezi yayo kubangela orbit side kakhulu futhi ukujikeleza okusheshayo bazungeza - ezinsukwini ezingu-88 nje kuphela. Futhi ngokushesha ukujikeleza Umhlaba kabili. Ngokuthakazelisayo, azungeza axis awo siqu le planethi kwenza cishe 59 izinsuku Earth. Lokhu kubuye ngenxa yokusondela inkanyezi futhi amandla ayo adonsela phansi, ngoba ubukhulu planethi incane izikhathi ezingaphezu kwezintathu kunomhlaba sika, ingasaphathwa mass. It kuvela ukuthi usuku mercurial kuyinto okubili kokuthathu ngonyaka lapha. Sekuyisikhathi eside i-Mercury kwaba komncane kunabo iplanethi Umhlaba qembu futhi ngemva bokuhlukaniswa Pluto kusukela isimo iplanethi - okwenzekile eminyakeni embalwa edlule ngenxa kubukezwe ososayensi leli qiniso - futhi ingabe baba iplanethi kulencane sonozungezilanga. Kuyathakazelisa ukuthi ngisho ezincane iziphuphutheki of Jupiter ne-Saturn - ngokulandelana, Titan futhi Ganymede. Nakuba esikhathini esidlule futhi ayikwazi ngokuthi amaplanethi. Kwaphela isikhathi eside mayelana Mercury cishe akukho lutho olwaziwa. Ucwaningo lwakhe oluphelele waqala ngesikhathi uhlanga isikhala kuphela "iMpi Yomshoshaphansi." Ngo-1973, e-umzimba Mariner 10 wethulwa owawungumnyaka izithombe zokuqala ezinhle iplanethi (ukuphasa "bheka" eduze Venus).
Isimo sezulu emhlabeni
Mercury has cishe akukho emoyeni, kodwa kukhona okuncane igesi siyazi:-hydrogen, i-sodium, umoya-mpilo, argon, i-potassium ne abanye. Naphezu kweqiniso lokuthi ingxenye enkulu ubuso bayo iyona iplanethi eziseduze Sun kuyinto Peklo yangempela (okushisa lapha kaningi ifinyelela degrees 400 Celsius), lapha kukhona izindawo lapho neze ukufinyelela imisebe yelanga. Akunjalo kudala, kwezinye asemigodini ezijulile zenyanga kwatholakala amanzi ice samanje. Akhona bakholelwa ukuthi Mercury, futhi kungase kube nezinye ice asemigodini, sise bafake izinti zalo. Izithombe eziye esikuthola Mariner 10 wabonisa ukuthi iplanethi esiseduzane ilanga e oyiyo kakhulu efana the Moon:-ke eminye kraterizirovana. wonke Kwamanzi embozwe eside ebumnyameni ochotshoziwe basalt uhlobo izidakamizwa. Njengengxenye ye-insimbi umzimba likhona kunazo zonke - 70%. Cishe ngoba ulokhu unjalo, futhi i-nucleus yayo. Kodwa, kubonakala sengathi, sekuyisikhathi eside iplanethi eziseduze Sun kwaba cool ngaphakathi asinawo umsebenzi umonakalo omkhulu kakhulu.
nezifundo
Namuhla ngokuhlanganyela ochwepheshe European futhi Japanese, uhlelo lapho ababili mkhathi, omunye okuzokwenza wehlele iplanethi futhi ngeke ukuhlola ubuso bayo nokujula izothunyelwa ngaphakathi kweminyaka eduze Mercury, kanye nezinye ukufunda nozibuthe.
