Venus ebusweni: ndawo, izinga lokushisa, incazelo iplanethi

I esiseduzane kuyiplanethi yethu igama elihle kakhulu, kodwa ebusweni Venus likwenza kucace ukuthi eqinisweni, ngokwemvelo yakhe akukho ukuthi angafana unkulunkulukazi wothando. Ngezinye izikhathi le planethi udadwabo twin eMhlabeni. Nokho, into kuphela labafanana - usayizi ofanayo.

Umlando yokutholakala

Ngisho nasezimweni ezikhululekile kungenzeka isibonakude encane ungakwazi ukulandelela shift disc planethi. UGalileo wokuqala wathola emuva 1610. Isibhakabhaka planethi wazibona Lomonosov e 1761, ngesikhathi lapho sekudlule ilanga. Kuyamangalisa ukuthi ukunyakaza okunjalo kwabikezelwa by ukubala, ngakho izazi zezinkanyezi ezimele lesi senzakalo nge look ekhethekile. Nokho, Lomonosov eyodwa kuphela yabhekisela yokuthi izibani disco "contact" namaplanethi emhlabeni zokugcina uvele kukhanya ezicashile. Obuka ngokuthi umphumela kuwumphumela kwalungiswa izinkunga zokubona ilanga imisebe emkhathini. Wayebheka lowo ebusweni Venus embozwe isimo kakhulu efana eMhlabeni.

iplanethi

Kusukela Sun, lo mhlaba endaweni yesibili. Ngesikhathi esifanayo, Venus iyona iplanethi esiseduzane Earth. Kulokhu, ngaphambi indiza emkhathini ngokoqobo, ukuze ufunde kabanzi mayelana nale nendikimba ethile esemkhathini cishe lutho esiye saphumelela. Yayaziwa kancane kakhulu:

• It esuswa ilanga ebangeni elikude eziyizigidi ezingu-108,2 amakhilomitha.
• Day Venus ihlala 117 izinsuku Earth.
• A revolution okuphelele emhlabeni inkanyezi yethu, yena kwenza cishe 225 izinsuku Earth.
• isisindo salo 0,815% we mass Zomhlaba, okuyinto ilingana 4.867 * 1024 kg.
• I ukusheshisa le mbulunga yethu - 8,87 m / s².
• Endaweni ebusweni Venus -. 460 200 000 sq Km.

I ububanzi we disc yomhlaba iplanethi lingaphansi ngu km 600 kuyinto 12104 km. Amandla adonsela phansi ngesikhathi esifanayo Cishe efanayo neyethu - sizokwenza kube amakhilogramu nesisindo amagremu 850 kuphela. Njengoba ubukhulu, ukwakheka kanye adonsela phansi le planethi okufana kakhulu imingcele eliwumhlaba, ubizwa ngokuthi "Earth-".

Venus ihlukile ngoba uzungeza ohlangothini olungafanele, ezenza kube eminye imihlaba. Ngokufanayo, "abaholayo" ngokwalo nokho Uranus. Venus emhlabeni axis awo, lapho umoya ihlukile kakhulu kwezethu, iyakunqanda izinsuku 243. I inzuzo yale planethi uzungeza ilanga ekwazile ukwenza 224,7 ngelanga, ilingana neyethu. Lokhu kwenza unyaka ku Venus mufushane kosuku. Ngaphezu kwalokho, imini nobusuku kule planethi ziyashintsha, kodwa inkathi ihlale ifana.

ebusweni

Ingaphezulu Venus ngenzele ngisho emathafeni ingxenye kakhulu inamagquma futhi cishe flat based nokuqhuma kwezintabamlilo. Labo abasele abanga-20% iplanethi - ezintabeni giant negama Ishtar Terra, Aphrodite Terra, insimu u-Alfa no-Beta. Lezi afanayo ngokuyinhloko lava-basalt. Kulezi zindawo, sebuningini asemigodini wathola ubukhulu kabani kusho kuyibanga elingaphezulu kwamakhilomitha angu-300. Ososayensi ngokushesha bathole impendulo yombuzo othi kungani akunakwenzeka ukuthola wentaba ku Venus lincane. Iqiniso lokuthi emkhathini, okwakuyoholela ushiye lokungcolisa elincane e ebusweni, nje akazange afinyelele yakhe, evutha emoyeni.

Ingaphezulu Venus amumethe ezihlukahlukene hlobo lwezintaba-mlilo, kodwa akucaci ukuthi ngabe umhlaba yaphela nge intabamlilo. Lo mbuzo ubaluleke eside kuyi ukuvela iplanethi. Geology "amawele" namanje kakhulu ayiqondakali kahle, okungukuthi, kunikeza ukuqonda eziyisisekelo isakhiwo nezinqubo yalesi nendikimba ethile esemkhathini.

Kuyinto ayikaziwa, kuyinto umnyombo planethi ketshezi izidakamizwa noma okuqinile. Kodwa ososayensi baye bathola ukuthi ayinayo conductivity kagesi, noma Venus kwakuyodingeka kazibuthe, ezicishe zifane nezethu. Ukungawuvivinyi ezinjalo namanje imfihlakalo izazi zezinkanyezi. Iphuzu ethandwa kakhulu umbono, ucishe echaza lesi simo sibangelwa ukuthi mhlawumbe nengaphakathi ukuqina nqubo akukaqali, ngoba jet convective idala kazibuthe amakhulu, namanje ayikwazi ozalwa.

Izinga lokubanda ezindaweni Venus ifinyelela 475 degrees. Kwaphela isikhathi eside izazi zezinkanyezi ayikwazanga ukuthola incazelo. Nokho, namuhla, ngemva kunobukhulu bendawo ucwaningo, kunenkolelo yokuthi isizathu Isivuvu. Ngokusho izibalo, uma iplanethi yethu kuqhamuka kwezigidi ezingu-10 kuphela. Amakhilomitha eduze inkanyiso, umphumela abaphumele lokulawula, ngakho ezaziyokwenzeka ukufudumala umane engelapheki Zomhlaba nokufa wazo zonke izinto eziphilayo.

Ososayensi eyenziwe isimo lapho Venus izinga lokubanda lalingu-hhayi okusezingeni eliphezulu ngakho, futhi wathola ukuthi ngesikhathi kwakuyoba efana izilwandle emhlabeni.

On Venus kukhona amapuleti lithospheric, okwakuyoholela kufanele zibuyekezwe e izigidi eziyikhulu iminyaka. Ngokusekelwe idatha etholakalayo, uqweqwe we planethi umile for million okungenani 500. Iminyaka. Nokho, lokhu akusho ukuthi Venus uzinzile. Ngenxa ukujula yayo ephakanyiswe izakhi amalahle uqweqwe, ukuthambisa ke. Ngakho-ke kungenzeka ukuthi kwaba ukukhululeka izinguquko global planethi kulindeleke.

Isibhakabhaka

Isibhakabhaka le mbulunga yethu inamandla kakhulu, okumenza aphuthelwe ukukhanya kwelanga. Kodwa lokhu kukhanya elifana ukuthi sibona zonke izinsuku - kungcono nje ababuthakathaka imisebe zihlakazeke. 97% i-carbon dioxide, mayelana 3% nitrogen, umoya-mpilo, amagesi inert and umusi - kukhona "ukuphefumula" Venus. Isibhakabhaka ayiyinhle kakhulu umoya-mpilo amaplanethi, kodwa compounds ezihlukahlukene ngokwanele ukuba sulfuric acid ne-sulfur dioxide ifu kwakhiwa.

Zogqinsi engezansi emkhathini ezungeze iplanethi kakhulu umile, kodwa iThrojani efaka isimeli seseva isivinini somoya ngokuvamile ngenhla 100 m / s. Lezo zivunguvungu nibuthana ndawonye, skirting yonke le mbulunga e kuphela ezine zosuku lwethu.

ucwaningo

Ezinsukwini zethu ukuhlola le planethi, hhayi kuphela izindiza kodwa ngosizo namagagasi omsakazo. izimo kakhulu okungekuhle emhlabeni kube nzima ukuba silifunde. Noma kunjalo, 19 imizamo yimpumelelo ukuthumela iinsetjenziswa kobuso nendikimba ethile esemkhathini lwenziwe past 47 iminyaka. Ngaphezu kwalokho, trajectory of the sasemkhathini eziyisithupha uzothola ukwaziswa okuwusizo mayelana Umakhelwane wethu wavele.

Kusukela ngo-2005, e emzileni iplanethi kuyinto umkhumbi, ukutadisha iplanethi nomkhathi wawo. Ososayensi banethemba lokuthola ukuthi ulisebenzise ukuze uvule ezingaphezu kweyodwa imfihlakalo Venus. Okwamanje, idivayisi adluliselwa Umhlaba semali Imininingwane azosiza ososayensi befunda okwengeziwe iplanethi okuningi. Ngokwesibonelo, kusukela okuthunyelwe kwabo, yabe seyaziwa ukuthi ion hydroxyl ekhona emkhathini Venus. Ososayensi cha fanele bono kanjani lokhu zingachazwa.

Omunye wemibuzo ukuthi ochwepheshe ungathanda ukuthola impendulo: onjani imfuyo endaweni engamamitha 56-58 amakhilomitha ubamba uhhafu wale misebe UV?

ukubukela

Lapho sekuhwalele Venus kungabonwa kahle. Ngezinye izikhathi ziyakhazimula ngokukhazimulayo ukuze kukhona ithunzi lezinto eMhlabeni (njengoba kunonyezi). Ezimweni efanelekayo, ke kungabonakala nasemkhakheni ngisho ngesikhathi sasemini.

amaqiniso ezithakazelisayo

• Ubudala planethi ngezindinganiso isikhala lincane kakhulu - iminyaka eyizigidi ezingu-500 ..
• Venus lincane kunomhlaba, amandla adonsela phansi ephansi, ngakho umuntu uyocabangela kule planethi esingaphansi ekhaya.
• Iplanethi ayinakho iziphuphutheki.
• Usuku emhlabeni isikhathi esingaphezu konyaka.
• Naphezu usayizi omkhulu, akukho wentaba ku Venus cishe ingabonakali, ngoba iplanethi ithukuswe kahle amafu
• izinqubo Chemical ngamafu ukukhuthaza ukwakheka acid.

Manje ngoba sewuyazi ukuthi okuningi mayelana ne-Earth sika ongaqondakali 'kabili'.
