Umhlaba u-Uranus

Iplanethi yeUranus

Njengoko sibonile kumanqaku angaphambili, yethu ISistema Solar Iqukethe iiplanethi eziyi-8 kunye neeplanethi Pluto eyekile ukuthathelwa ingqalelo enye ngenxa yobukhulu bayo. Sele sihlalutye nzulu Mercury, Venus, Marte, Umbhali y Saturn, sinokuthetha ngayo iplanethi u-Uranus. Yaziwa njengophawu oluhlaza kwaye ichaphaza kule posi ungafunda yonke into ngayo.

Ngaba uyafuna ukwazi ngakumbi ngeplanethi u-Uranus? Funda ukuze ufumane zonke iimfihlo zayo.

Iimpawu zika-Uranus

Ithathelwa ingqalelo njengesijikelezi-langa sesixhenxe kwinkqubo yethu yelanga ngokokusondela kwelanga. Esona sikufutshane yiMercury, ngelixa elona liphezulu yiNeptune. Ngapha koko, siyabona ukuba, kwiiplanethi ezinkulu ngobukhulu (ezibizwa ngokuba ziigesi ezinkulu), U-Uranus ukwindawo yesithathu.

Inobubanzi obuyi-51.118 km kwaye ibekwe kumgama ophindwe ngama-20 kuneplanethi yethu ngokubhekisele kwilanga. Igama layo lanikwa imbeko yothixo wamaGrike ogama lingu-Uranus. Ngokungafaniyo nezinye iiplanethi ezinamatye okanye iiplanethi ezinesiphithiphithi kulwakhiwo, i-Uranus inomgangatho ofanayo kwaye ulula. Umbala oluhlaza okwesibhakabhaka awubonakalisi kutyekelo lwemitha yelanga. Yenziwe ziigesi ezenza ukuba ube nalo mbala.

Ukuze ukwazi ukuyibona useMhlabeni, isibhakabhaka sasebusuku kufuneka sibe mnyama kakhulu, kunye nenyanga kwisigaba esitsha (Jonga izigaba zenyanga). Ukuba ezi meko ziyafezekiswa, kunye ne-binoculars sinokufumana ngokulula ukuba ichaphaza eliluhlaza.

Inzululwazi eyafumanisa le planethi yayinguWilliam Herschel kwaye wenza njalo ngoMatshi 13, 1781. Ngeli xesha, abantu abaninzi babezama ukwazi ngakumbi malunga nesibhakabhaka sethu kwaye bafumane into eyayisesibhakabhakeni. Ukufumanisa u-Uranus, uHerschel wasebenzisa iteleskopu awayeyakhile. Xa wachonga ichaphaza eliluhlaza okwesibhakabhaka esibhakabhakeni, waxela ukuba yayiyi-comet. Kodwa emva kokuyivavanya, kwaziwa ukuba yiplanethi.

Kubekwe kwinqanaba lesithandathu kuluhlu lweeplanethi kwiNkqubo yeSolar emva kweJupiter. Ukuhamba kwayo kukhulu kakhulu kwaye kuthatha malunga neminyaka engama-84 ukuyihamba kunokuba bekunokuhamba emhlabeni. Oko kukuthi, ngelixa iplanethi yethu ijikeleze iLanga amaxesha angama-84, u-Uranus wenze inye kuphela.

Ubume

ubungakanani bejupiter malunga noMhlaba

Iphantse yaliphinda-phinda kane ubungakanani beplanethi yethu kunye noxinano lwayo kuphela ngama-1,29 amagremu kwisentimitha nganye. Ekubunjweni kwayo ngaphakathi sifumana amatye kunye nezinto zomkhenkce zeentlobo ezahlukeneyo. Ingxondorha enamatye ininzi kwaye iigesi ezona zininzi kakhulu kwiatmosfera yayo yihydrogen kunye nehelium. Ezi gesi zimbini ziyinxalenye ye-15% yabo bonke ubunzima beeplanethi.

Yiyo loo nto ibizwa ngokuba yingxilimbela yegesi. Ukujikeleza kwe-axis yayo yokujikeleza kuphantse kube ziidigri ezingama-90 malunga nokujikeleza kwayo. Siyakhumbula ukuba iiplanethi yethu ngama-23 degrees. I-Uranus ikwanomsesane ofana noSaturn, nangona ungalinganiyo. Ukuthambeka kwe-axis kuchaphazela namakhonkco kunye neesathelayithi.

Ngenxa yokuthambeka okunje kwe-axis yayo, i-Uranus inamaxesha amabini onyaka kuphela. Iminyaka engama-42 ilanga likhanyisa isibonda esinye seplanethi kunye nezinye ezingama-42 esinye isibonda. Ukuba kude kakhulu neLanga, iqondo lobushushu eliphakathi lijikeleze -100 iidigri.

Inenkqubo yesangqa engenanto yakwenza nezo zikaSaturn kwaye ikwenziwe ngamasuntswana amnyama (Jonga Yintoni into emnyama?). Njengakwisayensi, uninzi lwezona zinto zibalulekileyo zifunyenwe zenzeka ngamabona-ndenzile ngelixa ujonge okona kulungileyo, ngokuchaseneyo. La makhonkco afunyanwa ngo-1985 xa iVoyager 2 space probe yayijonge ukufikelela kwiplanethi iNeptune. Kungelo xesha apho, ngokuhamba kwakhe, wayenokubona amakhonkco ka-Uranus.

Ngobuchwephesha bezi mini kunye nobuchwepheshe, kuye kwenzeka ukwazi ukuba enye yamakhonkco ayo aluhlaza okwesibhakabhaka kwaye enye ibomvu.

Ulwakhiwo lweUranus

Into eqhelekileyo kwiplanethi enamakhonkco kukuba zibomvu. Nangona kunjalo, kunethamsanqa kakhulu ukufumana amakhonkco aluhlaza. Kwimeko yayo yangaphakathi nangaphakathi Yenziwe nge-85% ye-hydrogen, i-15% ye-helium, kunye ne-methane encinci. Olu qulunqo lwenza ukuba umbala oluhlaza luhlaza.

Kukho ulwandle olungamanzi kule planethi, nangona ingenanto yakwenza naleyo sinayo eMhlabeni. Umoya wayo, owenziwe ziigesi ezidlulileyo, uyanyibilika njengoko usihla de ugqume wonke umkhenkce ngamanzi, i-ammonia kunye negesi yemethane. Sithe ulwandle alufani nantoni eMhlabeni kwaye kungenxa yokuba lwenziwe ngamanzi kunye neammonia. Oku kuyenza ibe nokuqhutywa kombane okuphezulu kwaye kuyingozi ngokupheleleyo.

Ngokungafaniyo nezinye iingxilimbela zegesi ezinje ngeJupiter kunye neSaturn, eUranus, umkhenkce ubalasele kwiigesi ngenxa yomgama omde ukusuka elangeni. Amaqondo obushushu asezantsi kakhulu kwaye oku kukhokelele kuluntu lwenzululwazi ukuba lubize ii-ice giants Izazinzulu khange zikwazi ukwazi isizathu sokuba i-axis yayo ithambekele kangako, nangona kucingelwa ukuba, ngexesha lokuyilwa kwayo, inokungqubana nenye iprotoplanet okanye ilitye elikhulu kwaye ithathe loo axis ngenxa yesibetho.

iplanethi ye-uranus

Ineesathelayithi ezingama-27 apho ezinye zaziwa ngakumbi kunabanye. IiSatellites azinkulu ngokwaneleyo ukuba zinokuba nomoya wazo. Baye bafunyanwa yi-Voyager 2. Babizwa ngokuba yiTitania kunye ne-Oberon. Enye ebizwa ngokuba nguMiranda yenziwe ngamanzi kunye nomkhenkce othuli kwaye ineyona ndawo iphakamileyo kuyo yonke iSolar System. Kukuphakama okungaphezu kwe-20 km. Iphindwe kalishumi kunoGrand Canyon kwiplanethi yethu.

Njengoko ubona, i-Uranus yiplanethi engayeki ukusothusa kwaye malunga nokusekuninzi ekufuneka ukwazi. Kungenzeka ukuba ngokuphuhliswa kwetekhnoloji sinokwazi ngakumbi nangakumbi ukutyhila zonke iimfihlo zayo.
