Iplanethi ezishisa esimisweni sonozungezilanga - Venus

iplanethi Engaqondakali eliseduze umakhelwane wethu - Venus. Ngetinkondlo wakhe namaculo, ngoba igama layo livela egameni unkulunkulukazi wothando! Iplanethi ezishisa esimisweni sonozungezilanga Sekuyizinkulungwane zeminyaka ngokweqile nabantu. Nokho, kungakhathaliseki ukuthi singakanani sasingazi ngawo, umbuzo planethi akubi ezincane. Lokhu nendikimba ethile esemkhathini uthembisa izimangaliso eziningi nemikarisomraro emangalisayo.

Ngokuvamile umuntu nesithakazelo esikhulu kulokho okufanekiselwa iyona iplanethi ezishisayo futhi enomoya zesimiso sonozungezilanga. On omunye wabo, ku lowo inenani lokushisa, futhi kuzoxoxwa ngezansi.

ukubukeka

Iplanethi ezishisa esimisweni sonozungezilanga liyabonakala kalula esibhakabhakeni ebusuku. Bona-ke kalula, ngokungafani kuya ukukhanya aphuzi izinkanyezi, ukukhanya kubonakala Venus kuyinto licace okuningi futhi uba nombala omhlophe. Thanda Mercury, iplanethi singasuki kinid at amabanga amade ukusuka elangeni. Lapho ukunwebeka esuswa inkanyiso ngu degrees 48 kuphela. Njengoba Mercury, it has kusihlwa nezikhathi ekuseni ukubonakala. Ezikhathini zasendulo, ngisho ngomqondo wokuthi lokhu kungabonakala esibhakabhakeni izinkanyezi ezahlukene. Ukugqama ebusuku iyona iplanethi ezishisa esimisweni sonozungezilanga umi endaweni 3rd.

Izici and orbit

Venus is closer kuze us kwamanye amaplanethi - konke at ibanga 40 million ukuze 259 km (kuye ngokuthi intuthuko ngaphakathi wo orbit). Ngokwesilinganiso, emhlabeni Sun, ihamba ngesivinini 35 km / s. Sibophezela indlela emhlabeni wonke ngo-224,7 izinsuku Earth, kuyilapho emhlabeni axis awo uzungeza izinsuku 243. Njengoba sazi ukuthi ukujikeleza iplanethi okuphambene kuya ukunyakaza nomjikelezo wawo, usuku Venusian ihlala 116,8 yethu ngezikhawu angu-24. Okungukuthi, imini nobusuku kule elula iplanethi 58,4 izinsuku Umhlaba ka.

Sesikubonile kakade waphendula lo mbuzo: "? Yini planethi ezishisayo" Manje ake sibheke abakuzuzile izinkomba main. I kwabantu of Venus cishe ilingane Earth - kuyinto 0,815 M. kuphela Kulokhu, lo engaba nhlobo eduze iplanethi yethu - 0,949 ka engaba Earth. Kwakunzima ukukala, ngoba iplanethi kufihliwe ngale kwamafu. Nokho, ukwenza lokhu kwaba Sibonga kungenzeka ukuba radar.

Ngokokuqala ngqá ukuba ukugcina ushintsho ibonakale disk isigaba sebekwazi e 1610, lapho uGalileo owasungula le isibonakude. Isigaba ushintsho olufana inyanga. Lomonosov, ubukele elisendleleni Venus yonkana inhlamvu yelanga, wathola usebe mncane nxazonke. Ngakho-ke, lapho kwavulwa emkhathini. Iplanethi ezishisa esimisweni sonozungezilanga namanje omunye eziphindwe enamandla kakhulu, kuyisipho ingcindezi at the amaqabunga 90 eziphindwe. Diana canyon phansi kungaba ozibongayo futhi inombolo enkulu - up 119. okusezingeni eliphezulu lokushisa kwamanzi kubangelwa Isivuvu planethi.

Isibhakabhaka

Isibhakabhaka planethi uyakwazi odlulayo imisebe eyingozi evela elangeni. Nokho, hhayi ngokuphelele, kodwa kuphela ngesimo emisebeni zihlakazeke ngu sebuningini izikhathi. Amafu kubonise iningi ngemisebe futhi kuphela ngaphansi kuka ingxenye yesine ka-ke singena ngaphansi. Isivuvu sizalwa nawo namaplanethi amaningi, kodwa kuphela Venus lokushisa aseduze laphezu komhlabathi - degrees 400. Kulesi lokushisa esiphezulu aziwa 480 degrees.

Iningi emkhathini - carbon dioxide. share Ezazimzungezile - 96,5%. Enye 3% nitrogen. Ingxenye esele siqukethe iphesenti igesi engaxubani namakhemikhali, amanzi, umoya-mpilo, i-hydrogen fluoride ne-hydrogen chloride. Ngaphambili kwakucatshangwa ukuthi fu ukuvikela ubuso kusukela ilanga, ngakho iplanethi uhlale omnyama. Nokho, manje kungase kutholakale ukuthi esikhanyayo usuku uhlangothi mayelana efanayo iplanethi yethu ngosuku yezimvula.

isakhiwo

I ezishisayo iplanethi ku solar system ine ophuzi esibhakabhakeni. Kusukela kwamanzi amakhilomitha 50 kokuwa ufasimbe elula. Ngenhla, kufika ku-70 km, kukhona amafu sakhiwa ngamaconsi amancane ka-sulfuric acid. Ngalesi engamamitha enkabazwe abayeki iziphepho esiqine kabani ijubane 100 km / h. Imimoya Kutholwe ngisho at 300 km / h.

Naphezu kweqiniso lokuthi Venus - iplanethi abaseduze nathi, ukubona ubuso bayo akunakwenzeka ngenxa fu kakhulu. Ezifundweni kudingeke ukuba sincike radar kanye iphenya interplanetary. Kwakuvamise ukuba sonke ebusweni embozwe izilwandle.

Ngo-1970, lo mkhumbi-mkhathi wakwazi ukuthola ulwazi oluthe xaxa mayelana iplanethi kunabo bonke eminyakeni eyedlule, kodwa wasebenza imizuzu 23 kuphela. Yena kubhidlika ngenxa kakhulu enqabayo izimo. Ngakho ngathola nezinga lokushisa elizosetshenziswa kule planethi, ingcindezi ngaphezulu, ukucacisa umkhathi. Kwatholakala ukuthi kwabantu amadwala phezu planethi - 2.7 g / cm³, okuyinto cishe kulingana basalts. Ngaphezu kwalokho, kwabikwa ukuthi kwakubulawa kwesigamu okuningi - silica, esele - a oxide magnesium kanye ne-aluminium alum.

Uma uyikha phezulu le akusho ukungena ilambu elikuhlaza, ngakho konke izithombe ezithwetshulwe une-tint orange. Imifudlana lava scree amatshe, ehlane enamadwala - konke lokhu kubonisa ukuthi umsebenzi zomhlaba akagcini ngalesi sikhathi.

ibalazwe

Eminyakeni eyalandela, nezinye iziteshi baye bafunda ngokwanele ukuba nethuba dala imephu Venus. Saze ephethwe ifotho cishe bonke ubuso. izintaba-mlilo Kutholakele, iningi okuyizinto esemthethweni, izintaba, imigodi yezintaba-mlilo. Iplanethi has amazwekazi amabili, ngamunye okuyinto esingaphansi eYurophu. Ngenxa ulwazi oluningiliziwe nezithombe yokudlulisela isithombe olunembile zomhlaba, akekho akungabazeki ukuthi iplanethi ezishisayo.

Kuze kube manje, thina kakhulu ukuqaphela Venus. I izici eziyinhloko yalesi nendikimba ethile esemkhathini ahlelwe kulesi sihloko. Kodwa okubaluleke kakhulu, ngokuhamba-agumenti siye sakwazi ukuphendula umbuzo obaluleke kunayo. Uyini iplanethi ezishisa esimisweni sonozungezilanga? Nokho, cishe isintu Uzofunda ngisho okuningi, ngoba umakhelwane wethu Galactic, kuyinto ekujaheni sokumukisa izimfihlo zabo.
