Iplanethi yeVenus

Iplanethi venus

Iplanethi yeVenus yiplanethi yesibini ukusuka kwiLanga kule yethu Inkqubo yesola. Ingabonakala eMhlabeni njengeyona nto ikhanyayo esibhakabhakeni, emva kwelanga neNyanga. Le planethi yaziwa ngegama lenkwenkwezi yakusasa xa ivela empuma ekuphumeni kwelanga nakwinkwenkwezi yangokuhlwa xa ibekwe ngasentshona ukutshona kwelanga. Kule nqaku siza kugxila kuzo zonke iimpawu zeVenus kunye neatmosfera yayo ukuze ufunde okungakumbi malunga neeplanethi kwiNkqubo yethu yeSola.

Ngaba uyafuna ukwazi yonke into malunga neVenus? Qhubeka ufunde 🙂

Ukujonga umhlaba weVenus

Iplanethi yeVenus evela eMhlabeni

Kumaxesha amandulo, inkwenkwezi yangokuhlwa yayibizwa ngokuba yiHesperus kunye nenkwenkwezi yasekuseni njengePhosphorus okanye iLusifa. Oku kungenxa yemigama phakathi kweendlela zeVenus noMhlaba ukusuka eLangeni. Ngenxa yemigama emide, uVenus ayibonakali ngaphezulu kweeyure ezintathu ngaphambi kokuphuma kwelanga okanye kwiiyure ezintathu emva kokutshona kwelanga. Izazi ngeenkwenkwezi zakuqala zazicinga ukuba iVenus inokuba yimizimba emibini eyahlukeneyo.

Ukuba ijongwa ngeteleskopu, iplanethi inezigaba ezinjengeNyanga. Xa iVenus ikwisigaba sayo esigcweleyo, inokubonwa kwisayizi encinci kuba ikwicala elikude nelanga eMhlabeni. Inqanaba lokuqaqamba eliphezulu lifikelelwa xa likwisigaba esinyukayo.

Amanqanaba kunye nezikhundla anazo uVenus esibhakabhakeni ziphindaphindwe kwisithuba seminyaka eli-1,6. Izazi zeenkwenkwezi zibhekisela kule planethi njengeplanethi yodade yoMhlaba. Kungenxa yokuba ziyafana ngobukhulu, njengobunzima, uxinano, kunye nevolumu. Zombini ziyile ngaphezulu okanye ngaphantsi ngaxeshanye kwaye zixinaniswe kwi-nebula efanayo. Konke oku kwenza Umhlaba kunye neVenus ziiplanethi ezifanayo.

Kucingelwa ukuba, ukuba kungangumgama ofanayo ukusuka eLangeni, uVenus angabamba ubomi kanye njengoMhlaba. Ukuba kwenye indawo yeNkqubo yeLanga, iye yaba yiplanethi eyahluke mpela kule yethu.

Iimpawu eziphambili

Ukutshisa iPlanethi yeVenus

IVenus yiplanethi engenazilwandle kwaye ijikelezwe yimo enzima kakhulu eyenziwe ikakhulu yicarbon dioxide kwaye phantse ayinawo umphunga wamanzi. Amafu aqulathe isalfure acid. Phezulu sidibana Uxinzelelo lomoya ophindwe ngama-92 kuneplanethi yethu. Oku kuthetha ukuba umntu oqhelekileyo akakwazanga ukuhlala umzuzu kubuso beplanethi.

Ikwabizwa ngokuba yiplanethi etshisayo, kuba umphezulu uneqondo lobushushu lama-482 degrees. La maqondo obushushu abangelwa yimpembelelo enkulu yegreenhouse eveliswa ngumoya oxineneyo kunye nobunzima. Ukuba kufunyenwe isiphumo sokugcina ubushushu kwiplanethi yethu ukugcina ubushushu kunye nomoya ocekeceke kakhulu, cinga ngomphumo wokugcina ubushushu oya kuba nomoya onzima. Zonke iigesi zivaleleke emoyeni kwaye azikwazi ukufikelela emajukujukwini. Oku kubangela ukuba iVenus ishushu kunokuba iplanethi yemekyuri nangona ikufutshane neLanga.

Usuku eVenusian ineentsuku ezingama-243 zomhlaba kwaye inde kunonyaka wayo weentsuku ezingama-225. Kungenxa yokuba uVenus ujikeleza ngendlela engaqhelekanga. Ikwenza oko ukusuka empuma ukuya entshona, kwicala elichaseneyo neeplanethi. Kumntu ohlala kule planethi, wayenokubona ukuba iLanga liyakuphuma njani entshona kwaye ukutshona kwelanga kuyakwenzeka empuma.

Emoya

Umoya weVenus

Iplanethi yonke igutyungelwe ngamafu kwaye inomoya oxineneyo. Ubushushu obuphezulu benza izifundo ezisuka eMhlabeni zibe nzima. Phantse lonke ulwazi olufunyenweyo malunga neVenus lufunyenwe kusetyenziswa izithuthi zasemajukujukwini ezikwaziyo ukwehla kuloo mmandla uxineneyo uthwele iiprobes. Ukusukela ngo-2013 Imishini engama-46 yenziwe kwiplanethi etshisayo ukuze ufumane okungakumbi ngaye.

Iatmosfera yenziwa phantse yicarbon dioxide. Le gesi yigreenhouse gas enamandla ngenxa yokukwazi kwayo ukugcina ubushushu. Ke ngoko, iigesi ezikwiatmosfera azinakho ukufudukela emajukujukwini kwaye zikhuphe ubushushu obuqokelelweyo. Isiseko sefu yi-50 km ukusuka kumphezulu kwaye amasuntswana kula mafu ubukhulu becala agxile kwisulfuric acid. Iplanethi ayinamandla abonakalayo omazibuthe.

Ukuba phantse i-97% yeatmosfera yenziwe nge-CO2 ayothusi kangako. Kwaye kukuba umhlaba womhlaba unexabiso elifanayo kodwa ukwimo yelitye lekalika. Yi-3% kuphela yomoya oyi-nitrogen. Amanzi nomphunga wamanzi zizinto ezinqabileyo kakhulu kwiVenus. Izazinzulu ezininzi zisebenzisa ingxoxo yokuba, ukusondela kwilanga, kuxhomekeke kwisiphumo esinamandla kakhulu sokukhusela ubushushu obukhokelela ekukhuphukeni kweelwandle. Iiathom zeHydrojeni kwiimolekyuli zamanzi zinokulahleka esithubeni kunye neeathom zeoksijini kuqweqwe.

Enye into ekucingelwa ukuba iVenus ibinamanzi amancinci ukusuka ekuqaleni kokuyilwa kwayo.

Amafu kunye nokwenziwa kwawo

Thelekisa phakathi kweVenus noMhlaba

Iasidi yesulphuric efumaneka emafini ikwahambelana naleyo yoMhlaba. Iyakwazi ukwenza inkungu entle kakhulu kwi-stratosphere. Iasidi iwela emvuleni kwaye iphendula ngezinto zomhlaba. Le planethi yethu ibizwa ngokuba yimvula eneasidi kwaye ingunobangela womonakalo omninzi kwindalo esingqongileyo njengamahlathi.

KwiVenus, iasidi iyaphuphuma emazantsi emafini kwaye ayizikhuphi, kodwa ihlala emoyeni. Umphezulu we amafu ayabonakala eMhlabeni nakuVulindlela weVenus 1. Uyayibona indlela esasazeka ngayo njengobusi obungama-70 okanye ama-80 eekhilomitha ngaphezulu komphezulu womhlaba. Amafu anezinto ezimdaka ezityheli ezimthubi kwaye afunyanwa kakuhle kubude obude kufutshane ne-ultraviolet.

Umahluko okhoyo kumxholo wesalfure dioksidi esemoyeni ungabonisa uhlobo oluthile lwentaba-mlilo esebenzayo kwiplanethi. Kwiindawo apho kukho uxinzelelo oluphezulu, kunokubakho intaba-mlilo esebenzayo.

Ndiyathemba ukuba ngolu lwazi ungafunda okuninzi malunga nenye iplanethi kwiNkqubo yeLanga.


Umxholo wenqaku uyabambelela kwimigaqo yethu imigaqo yokuziphatha yokuhlela. Ukuxela impazamo cofa apha.
