El iplanethi venus yenye yeeplanethi engenazo iisathelayithi zendalo. Yiplanethi yesibini ukusuka elangeni kwinkqubo yethu yelanga kwaye inokubonwa kwiplanethi yethu njengento eqaqambe kakhulu. Yaziwa njengeplanethi yenkwenkwezi yakusasa kuba ibonakala ngathi ilanga litshonile. Ibekwe kwindawo yasentshona ukuze ivele. Kukho ezinye iithiyori ezemidlalo esizibonayo zingenazo iisathelayithi kwaye ke sizakuthetha ngazo Iisathelayithi zetyhefu.
Kule nqaku siza kukuxelela yonke into ofuna ukuyifumana malunga neesathelayithi zeVenus kunye neemfihlo zabo.
Iimpawu zeplanethi yeVenus
Okokuqala, kukwazi ezinye zeempawu zalo mhlaba ngaphambi kokwazi iimfihlelo ezingqonge inyani yokuba siyabona ukuba ayinazo iisathelayithi. Ukususela kumaxesha amandulo, le planethi yayisaziwa ngegama likaHesperus xa ujongwa ngorhatya. Wayenelinye igama kwaye wayenguLusifa xa wayebonwa kwasekuseni. Siyayazi loo Venus ayinakubonakala ngaphezulu kweeyure ezi-3 ngaphambi kokuphuma kwelanga okanye iiyure ezi-3 emva kokutshona kwelanga. Izazi ngeenkwenkwezi zokuqala ezaqala ukufunda uVenus zazicinga ukuba inyani yokuba zizinto ezimbini ezahlukileyo ngokupheleleyo zezulu inokuba yinyani.
Le planethi inezigaba ezahlukileyo njengenyanga ukuba ibonwa kwiteleskopu. Ngalo lonke ixesha iVenus igqibezela ukugqitha kwayo ukuya kwelona liphezulu inokubonwa kubungakanani obuncinci kuba ikwicala elikude nelanga. Ngokuchasene noko, nangona kubonakala ngathi akukho ngqiqweni, inqanaba eliphezulu lokuqaqamba kwale planethi ifikelelwa xa ikwisigaba esandayo.
Into efanayo nento eyenzekayo nenyanga yenzeka ngeVenus. Izigaba kunye nezikhundla zayo ziphindaphindwe kwisithuba esimalunga neminyaka eyi-1.6. Izazi zeenkwenkwezi zibhekisela kule planethi njengoMzalwana womhlaba womhlaba. Kwaye yiplanethi efanayo ngobukhulu, ubunzima, uxinano kunye nomthamo. Izazinzulu zicinga ukuba kunjalo kwaye iVenus yayingumgama ofanayo ukusuka elangeni lomhlaba wethu onokuthi ubambe ubomi. Kodwa, ekubeni ikwenye indawo yesixokelelwano selanga, iye yaba yiplanethi eneemeko ezahluke kakhulu kwezethu.
Eminye iminqweno
Phakathi kweempawu eziphambili ezinazo kukuba ayinazilwandle kwaye ayinazo iisathelayithi. Iisathelayithi kufuneka zibe nezimvo ezithile esizibonayo apha ngezantsi. Ikwangqongwe ngumoya onzima kakhulu onobumba ikakhulu bekhabhon diokside kwaye ke akukho mphunga wamanzi. Amafu adadayo anokubonakala ngeeteleskopu ezinamandla ngakumbi enziwe ngeasidi yesalfure. Ngokungafaniyo noko kwenzeka kwiplanethi yethu, Sifumana uxinzelelo lomoya ophindwe ngama-92 ngaphezulu. Oku kuthetha ukuba akukho mntu unokuphila kwiplanethi ngomzuzu.
Enye yezinto ezibangela umdla kule planethi kukuba yaziwa njengeplanethi etshisayo. Kwaye kukuba ubushushu kumphezulu wayo bujikeleze ama-482 degrees. Iqondo lobushushu libangelwa yimpembelelo enkulu yegreenhouse ethi ivelise umoya wayo uxinene kwaye unzima. Ngokungafaniyo neplanethi yoMhlaba, enefuthe lokugcina eluhlaza elinceda ukukhuthaza amaqondo obushushu amnandi, nantsi iyabaxwa. Zonke iigesi zivaleleke emoyeni wayo kwaye azikwazi ukufikelela emajukujukwini. Oku kubangela ukuba iVenus ishushu kuneMercury nangona isondele elangeni.
Usuku olunye kwiVenus lilingana neentsuku ezingama-243 eMhlabeni kwaye lude kunonyaka walo ophela okwiintsuku ezingama-225. Oko kukuthi, kuthatha ixesha elide ukuzijikajika kunokujikeleza ilanga. Into yokugqibela enomdla kukuba ukuba umntu ebenokuhlala apha, banokubona ukuba ilanga liphuma njani entshona kwaye ukutshona kwelanga kuya kuba sempuma.
Iisathelayithi zeVenus
Kukho iingcamango ezininzi zeesathelayithi zeVenus kwinkqubo yelanga. Ngaphandle kwenyani yokuba zininzi iinyanga kwisixokelelwano selanga, ukusuka kwezinye ezingenamoya ofana neNyanga ukuya kwezinye onomoya ofanelekileyo njengeTitan, uyabona ukuba iVenus ayinazo iisathelayithi. Siyazi ukuba iVenus neMercury zezona zijikelezi-langa zikummandla welanga ezingenazo iinyanga ezizijikelezayo. Isizathu soku yinto efunyaniswe zizazinzulu ezininzi kwimbali.
Kulapha apho izazi ngeenkwenkwezi zijonga khona amathuba athile anokuchaza ukuba kutheni ezi planethi zimbini zingenazo iinyanga. Eyokuqala yeyokuba iisathelayithi zendalo zafakwa kumxhuzulane wezi zijikelezi-langa xa zazigqitha kufutshane nazo. Inokuba njalo imeko ye- las iinyanga ezincinci zeemars eyaziwa ngokuba yiPhobos kunye neDeimos. Enye imeko enokuqwalaselwa kukuba iplanethi iVenus iya koyisa ifuthe elikhulu eliya kuthi lilahle inxenye yezinto zalo emajukujukwini.

Enye yeethiyori ezikhoyo malunga neesathelayithi zeVenus kukuba inokwenziwa kunye neplanethi ngokongeza ngokubanzi izinto ezazishiyekile ngexesha lokwenziwa kweVenus. Ngale ndlela, iinyanga ziya kuba yinxalenye yeplanethi xa iyonke.
Ithiyori malunga neesathelayithi zeVenus
Ukuthathela ingqalelo ezinye zeethiyori ezinesiphithiphithi kwaye zinamandla ezichaphazela inkqubo yokuqala yelanga, kufuneka sazi ukuba bekukho amawaka amaqumrhu amancinci ajikeleza phakathi kokujikeleza kweeplanethi ezahlukeneyo. Kulapha apho izazinzulu zachukunyiswa yinto yokuba asinaso isathelayithi yendalo. Apha ubuzwa umbuzo wokuba ngaba uVenus wayenokuba neenyanga ngaphambili. Abanye abaphandi baveze uphando apho banokubanga loo nto UVenus wayenokuba nobunzima ubuncinci kwiimpembelelo ezi-2 ezinkulu ngemizimba emikhulu kwixa elidlulileyo benza iinyanga zabo zanyamalala.
Kungenzeka ukuba, uVenus wayenenyanga encinci eyakhiwe ngenxa yenkunkuma eyakhutshwa kwiplanethi emva kwempembelelo enkulu yomzimba omkhulu. Ngenxa yamandla omxhuzulane, Isathelayithi yayihamba kude kube ingakhange ichukunyiswe ngumxhuzulane weVenus. Ngale ndlela, kunokwenzeka ukuba iplanethi yoyise impembelelo elandelayo kwaye iguqule ukujikeleza kweplanethi, kubangele iziphumo ezichaseneyo.
