Ubukhulu Mercury sika: le ukuqinisela noma ushintshe?

Mercury uvamise kubonakala ekuseni nobe ntsambama - ngalesi sikhathi kubonakala inkanyezi ekhanya esibhakabhakeni ukuhwalala. Ezikhathini zasendulo, ngisho sacabanga ukuthi izinkanyezi ezimbili ezahlukene - izizwe abahlala umhlaba ngaleso sikhathi, wanikeza lezi "zinkanyezi" kukhona amagama amabili - Gore nokukhanya Rogineya Buddha, uHermesi, u-Apollo.

Uhlolojikelele

Mercury - the esiseduzane inkanyiso amaplanethi yesimiso sonozungezilanga. He is emincane kunayo yonke "umndeni", kodwa lunesibalo eliphezulu kakhulu. Cishe ama-80% mass isiyonke into ewela ekujuleni kwenhliziyo. I ububanzi Mercury imayelana 5000 amakhilomitha.

Mercury uzungeza ngisheshe ukwedlula kwamanye amaplanethi. Lokhu kwenzeka kulo awuhambanga kude orbit. Mercury ngonyaka - izinsuku Earth 88 kuphela. Ngesikhathi esifanayo emhlabeni kuye ngaleso sikhathi iplanethi uzungeza izikhathi eyodwa nengxenye nje. Ngakho, ilingana amahora 59 emhlabeni Mercurian. Kusukela ekuphumeni kwelanga njengoba maqembu futhi benza 179 izinsuku Earth.

Naphezu kweqiniso lokuthi kule planethi kuxhopha ngokwanele, futhi ububanzi Mercury ikuvumela ukuba khona isesihlalweni Umhlaba, sibona akusiyo kaningi. Lokhu kwenzeka ngenxa yokuthi Mercury sisondele kakhulu ilanga. Ukuze ubone lokhu, ngakho unga ngesikhathi lapho enaka omunye umuntu kude ilanga ibanga esiphezulu.

ubukhulu Mercury sika lithé ukuba likhudlwana kune-Moon, kodwa kwabantu iphezulu kakhulu. Kungenzeka ukuthi le kwabantu nendawo - 8900 amakhilogremu ngalinye imitha cubic. Lokhu kusikisela ukuthi umongo i-iron. Ngaphezu kwalokho, kule ndaba, umongo kokuba engaba 1800 km, ¾ we engaba iplanethi.

Empeleni, kwaba ubukhulu Mercury uvumela ezinye izazi kusukela ngekhulu XIX ukuphikisana ngokuthi ngaphambili kule planethi has a satellite Venus, elalahleka kule ngozi. Kungenzeka ukuthi le ngozi kwaba ukungqubuzana kwenye iplanethi, lapho Mercury wayengekho kuphela orbit zamanje, kodwa futhi wathola okuningi umonakalo waphawula namuhla izithombe iplanethi.

ebusweni

Bheka ebusweni Mercury sika Lwenziwe ngo-1974, lapho bedlula "Mariner 10" wathumela izithombe. Kwatholakala ukuthi le planethi ebomvu kakhulu efana inyanga yethu. "Umhlaba" Mercury embozwe yamadwala nasemigodini asemigodini, okuhlanganisa nokuba ifomu ray diverging. Lezi asemigodini akhiwa ukushayisana eningi emkhathini. Rocks futhi sekukhona ngesikhathi lapho umnyombo iplanethi wenqulu, edonsa ngesikhathi esifanayo nebhalsamu namagxolo.

Njengoba Mercury - iplanethi, ukukhanya likhipha ngeke. Siyakubona ke njengoba inkanyezi kuphela ngoba surface iplanethi sika has reflectivity ezinhle - isesihlalweni Umhlaba kubonakala ukukhanya kwelanga.

Isibhakabhaka

Ezinye izimpawu ibonisa isimo emhlabeni Mercury. Kodwa kungaphezu - izinkulungwane zezikhathi - uphansi kunomhlaba. It ayikuvumeli ukuze ifudumale noma ukuvikela iplanethi kusuka phezu-bafudumale. Yingakho emhlabeni kunomehluko omkhulu phakathi kosuku nobusuku okushisa.

Cishe ezivamile Mercury umoya yakhiwa helium, i-hydrogen, carbon dioxide, neon, futhi argon, umoya-mpilo. Budebuduze ukuze inkanyiso kusikisela ithonya ama-solar wind emhlabeni. Lokhu kwandisa amathuba iplanethi ensimini kagesi kabili okukhulu ngaphezulu kuka phansi, futhi ngaleyo ndlela esitebeleni kakhulu.

lokushisa

Banikezwe ukungabi pheze ephelele emkhathini womhlaba, ebusweni uyabaselwa emini futhi epholisa off kakhulu ebusuku. Nenkabazwe, waphenduka maqondana ilanga eliwu 440 degrees Celsius. usetha Ngakho Nenkabazwe abakwazi ukugcina ukushisa ngaphandle emkhathini, selehlile -180 degrees.

ubukhulu

Ububanzi Mercury kuyinto 4878 amakhilomitha. Lena cishe 2.5 izikhathi ezincane kuno ubukhulu iplanethi yethu, kodwa izikhathi 1.5 kunangendlela the Moon. Kwaphela isikhathi eside kwakucatshangwa ukuthi ububanzi Mercury Km is akazange kwashintsha. Nokho, ucwaningo lwamuva olwenziwa futhi idatha ethunyelwe mkhathi ukuba bathi lingakanani washintsha. idatha okusha Unike amandla akhona ukunquma ukuthi zokugcina 4 billion eminyakeni ziye zashintsha ivolumu planethi. I ububanzi we iplanethi Mercury ngalesi sikhathi kwehle ngo-amakhilomitha 14. I udonga lwangaphandle iplanethi - kungcono ipuleti eyodwa nje, ngokungafani Earth, lapho ebusweni yakhiwa panel eziningana.

Ngenxa Ukupholisa futhi okwalandela kokucindezelwa cortex ubukhulu kakhulu iplanethi Mercury lancipha. Ngaphezu kwalokho, lokhu kwehla mkhulu kakhulu kunezinye izimo ezifanayo lwenzeka inyanga noma Mars. Idatha ukuthi sidlulile mkhathi "Messendzher", kusinike ithuba ukufunda ukuvela iplanethi. Mhlawumbe ngokushesha silindele emizweni ezintsha.

Isibikezelo sezulu sezinsuku

Yiqiniso, le simo esiqondile esikhathini esizayo ukunikeza okungekho omunye. Ubufakazi obanelisayo nokucabanga enengqondo kuphela okunye epholisa iplanethi Mercury ububanzi zingancishiswa ngaphezulu.

Nokho, kukhona inguqulo ye okuyinto nasesikhathini esikude esizayo kule planethi yethu uzobhekana ohlelweni. Mercury noma iwe ilanga, noma yokukhubazeka ku Venus. Nokho, lokhu kuzokwenzeka ngaphambili kuka eminyakeni eyizinkulungwane zezigidi.

Ososayensi base-France udale imodeli ukuziphatha sonozungezilanga ezilandelayo iminyaka 5 bhiliyoni. Ngesisekelo idatha etholakalayo, kwaphethwa ngokuthi ngu 3.5 billion neminyaka ezungeza kwamaplanethi aphambana, ibangela ukushayisana. Kulesi imodeli, cishe wonke amaplanethi sesiseduze ibanga yingozi Umhlaba, ngaphandle Mercury, okuyinto amathuba okuba uwele elangeni.

Noma kunjalo, ososayensi abaningi bevuma ukuthi amathuba ikusasa elinjalo -% 1 kuphela. Lokhu kubonisa imodeli ukuthi, ngokomthetho, kungenzeka. Ngaphezu kwalokho, eminyakeni 3.5 billion - kuba ngesikhathi esibalulekile, futhi ngaleso sikhathi isintu, cishe ngeke neze namanje, njengoba nalokho ubuso.
