Iinyani ezipholileyo kakhulu malunga neVenus

Ukuba ukhe wajonga ngobusuku obuneenkwenkwezi, ngokuqinisekileyo iVenus ayikhange ibambe iliso lakho, nokuba ubungayazi. Iplanethi ikhanya kakhulu kuyo nayiphi na into esibhakabhakeni sasebusuku boMhlaba, emva kweLanga neNyanga. Ukubengezela kwayo okumangalisayo kwenze ukuba ibe yeyona nto iphambili kwimpucuko kuluntu lonke ukusukela ngoko iirekhodi bezikhona. IVenus yayikwayiplanethi yokuqala ukuba uhambo lwayo lucetywe ukunqumla isibhakabhaka ebusuku, kwakudala njengenkulungwane yesibini ngaphambi kweXesha Eliqhelekileyo.

Iinyani ezimbalwa ezikhawulezayo

• IVenus kuphela kweplanethi ebizwa ngegama lomntu obhinqileyo kwiSolar System.
• IVenus ayinazo iinyanga, kwaye ayinazo imisesane.
• Umphezulu weVenus uqikelelwa ukuba uneminyaka engama-300 ukuya kuma-400 ezigidi ubudala. Umphezulu woMhlaba, xa uthelekisa, uneminyaka eyi-100 yezigidi kuphela ubudala.
• IVenus ineyona ndlela ijikeleze ilanga kuzo zonke iiplanethi ezikwiSolar System.

Ithiywe ngesithixokazi

IVenus ibizwa ngokuba sisithixo samandulo samaRoma sobuhle nothando lukaThixo. AmaRoma amandulo ayekholelwa ukuba kwakukho ezinye izijikelezi-langa ezine kuphela kwiSixokelelwano sezijikelezi-langa, ngaphandle koMhlaba—yaye iVenus yayiqaqamba neyona nto intle kuzo zonke. Igama lothando leplanethi kudala lidibanisa nothando kunye nobufazi kuyo yonke imbali.

Ikwabizwa ngokuba yinkwenkwezi yasekuseni kunye nenkwenkwezi yangokuhlwa

AmaGrike amandulo ayekholelwa ukuba iVenus yayizizinto ezimbini ezahlukileyo, inkwenkwezi yasekuseni kunye neenkwenkwezi zangokuhlwa.

Xa ikwicala elinye lelanga, iVenus ibonakala ikhokela ilanga njengoko linyuka lisiya esibhakabhakeni, liphuma kwiiyure ezimbalwa ngaphambi kokuphuma kwelanga. Liya kwandula ke, njengokuba izulu liqaqamba, libe ngukukhanya kwemini. Le yikhwezi lokusa.

Xa iVenus ikwelinye icala lelanga, ibonakala ilandela ukutshona kwelanga. Njengoko isibhakabhaka simnyama, siqaqamba esibhakabhakeni ebusuku. Le yinkwenkwezi yangokuhlwa.

AmaGrike amandulo ayebiza ikhwezi lokusa iPhosphoros okanye lowo uzisa ukukhanya. Kwaye bayibiza inkwenkwezi yangokuhlwa ngokuba nguHesperos, inkwenkwezi yangokuhlwa. Akuzange kube kwiinkulungwane ezimbalwa kamva apho kwavela kumaGrike ukuba zombini iinkwenkwezi yayizizo. efanayo umzimba wesibhakabhaka—okuphela kukaVenus.

Yiplanethi engudade woMhlaba

IVenus yeyona planethi ikufutshane noMhlaba kwiSolar System, kwaye zombini iiplanethi ziyafana ngobukhulu. Ngezo zizathu, zihlala zibizwa ngokuba ziiplanethi ezingoodade. Ubunzima beVenus bumalunga ne-81% yobunzima boMhlaba, kwaye kukho kuphela malunga neemayile ezingama-400 ububanzi phakathi kwezi planethi zimbini.

Imozulu yeVenus isenokuba yayifana kakhulu neyoMhlaba, kwiibhiliyoni zeminyaka eyadlulayo. Kukho ubungqina bokuba iVenus yayikhe yaba neelwandle ezinkulu okanye amanzi amaninzi. Nangona kunjalo, ngenxa yobushushu obuphezulu beplanethi kunye nomoya onobutshaba, nawuphi na umkhondo wamanzi sele ubilile.

Kushushu kakhulu

Xa kuziwa kwiiplanethi ezishushu, iVenus ithatha indawo ephezulu. Ngobushushu bomphezulu obuphakathi kwe-863°F, yeyona ishushu kwiSolar System yonke. Iplanethi inomaleko wamafu angqindilili owenziwe yi-96.5% yekharbon diokside, ethintela phantse bonke ubushushu ukuba bubaleke, kwaye ibangele i-greenhouse effect. Ngenxa yoku, nayiphi na imithombo yamanzi enokubakho kudala yaba ngumphunga, kwiibhiliyoni zeminyaka eyadlulayo.

Amaqondo obushushu eVenus awahlukanga kakhulu phakathi kwemini nobusuku, ngenxa yentshukumo ebudoda yomoya welanga unqumla phezu komhlaba.

Kuba iVenus ayithambeki kwi-axis yayo, ayinawo nawaphi na amaxesha onyaka.

Ijikeleza ngasekunene

Uninzi lweeplanethi, kubandakanywa noMhlaba, zijikeleza ngokuchasene ne-axis yazo. IVenus yona ijikeleza ngasekunene—kwelinye icala kunezinye iiplanethi. Oku kubizwa ngokuba yi-retrograde rotation, kwaye kusenokwenzeka ukuba kungenxa yontlitheko lwe-asteroid eye yawisa iplanethi kwindlela yayo yokuqala yokujikeleza. Ekuphela kweminye iplanethi kwiSixokelelwano seSolar kunye nokujikeleza kwakhona kwe-Uranus.

iqhekeza elinye ubomi benene

Iintsuku zayo zinde ngendlela emangalisayo

IVenus inezona ntsuku zinde kuzo zonke iiplanethi ezikwisijikelezi-langa. Olunye usuku kwiVenus luhlala ixesha elide kunonyaka walo wonke. Ukujikeleza okucothayo kwi-axis yayo kuthetha ukuba iplanethi ithatha iintsuku ezingama-243 zoMhlaba ukugqiba ukujikeleza okunye. Ukujikeleza kweplanethi ilanga kuthatha iintsuku ezingama-225 zomhlaba. Oku kuthetha ukuba unyaka kwiVenus ziintsuku zoMhlaba ezili-19 mfutshane kunosuku olunye kwiVenus! Esi siganeko sinokuba sisiphumo sokujikeleza okungaqhelekanga kweplanethi.

Kuphantsi koxinzelelo olukhulu

Uxinzelelo lwe-atmospheric kumphezulu weVenus luphindwe kayi-93 into esidibana nayo apha eMhlabeni. Ukuziva olo hlobo loxinzelelo kwesi sijikelezi-langa, kuya kufuneka untywile ngaphezulu kwesiqingatha semayile ngaphantsi kolwandle. Oku kuthetha ukuba nasiphi na i-meteorite encinci engena kumoya we-Venus itshiswa luxinzelelo lodwa⁠— yiyo loo nto iplanethi ingenayo imingxuma emincinane kumphezulu wayo.

Kuninzi lwembali, izazi ngeenkwenkwezi zazingenandlela yokwazi ukuba yintoni engaphantsi kwamafu ashinyeneyo kaVenus kwaye babenomfanekiso-ngqondweni wehlabathi elishinyeneyo elishinyeneyo elinamahlathi kunye nemvula engagungqiyo ngaphantsi. Babengenakuphazama ngakumbi. Ayisiyiyo iVenus kuphela, eyona planethi ishushu kwiSolar System, kodwa ikwanendawo enobutshaba obumangalisayo.

Umoya weplanethi unamaleko amabini: umaleko wokuqala yibhanki yefu egubungele iplanethi yonke, kwaye umaleko wesibini ubandakanya yonke into engaphantsi kwala mafu.

Umaleko welifu, owenziwe ubukhulu becala yiasidi yesulfuric kunye nesulfure dioxide, uxinene kangangokuba i-60-75% yokukhanya kwelanga efika kuVenus iphinde ibonakale kanye esithubeni. Iatmosphere yayo engqindilili ngokungenakungeneka ithetha ukuba ayipheleli nje ekubeni ishushu ngendlela engathethekiyo, kodwa akukho kukhanya kwelanga kufikelela phezulu.

Igqunywe ziintaba-mlilo

IVenus inezona ntaba-mlilo zininzi kuzo naziphi na iiplanethi ezikwiSolar System ngokudubula okude. Izazinzulu ziye zabala ngaphezu kwe-1,600 yeentaba-mlilo ezinkulu okanye iintaba-mlilo, ezineentaba-mlilo ezininzi ezincinci. Akukho mntu ulaziyo elona nani liqinisekileyo, kodwa kusenokubakho ngaphezu kwe-100,000⁠— okanye kwane-1,000,000.

Wonke umphezulu weplanethi ugqunywe ziimpawu zentaba-mlilo kunye nokuhamba kodaka oludala. Kukho malunga ne-1,000 lemingxuma yentaba-mlilo kunye neentsalela zemingxuma ezinomlinganiselo ongaphezulu kweemayile ezingama-600 ububanzi.

Intaba-mlilo ibisoloko inendima enkulu ekubumbeni umphezulu weVenus. Kukho ubungqina bokuba intaba-mlilo iqukuqela malunga ne-300 - 500 yezigidi zeminyaka eyadlulayo yaphinda yaphinda yavela kwakhona emhlabeni.
