Oberon, Uranus satellite: incazelo

Naphezu kwentuthuko kwezesayensi nobuchwepheshe, eziningi izimfihlakalo yonke kuhlale kuyimfihlakalo esintwini. Ucwaningo izindikimba zasezulwini, kuhlanganise izinyanga namaplanethi yesimiso sonozungezilanga, lihlotshaniswa nobunzima obuningi. Amabanga ungavumeli ukuba ababheke ngokuningiliziwe. Oberon, satellite planethi Uranus, kanye nezinye "abangane" bakhe namanje balinde isikhathi sabo ekucwaningeni okunzulu.

indaba

Inani satellites Uranus ifinyelela amayunithi 27. Basuke zihlukaniswe ngamaqembu:

• ingaphakathi;
• zangaphandle;
• kwekulu.

"Inhlawulo" Yangaphakathi has 13 izigaxa amnyama ngenhloso ububanzi kusukela km 50 150. Bonke ilingise cishe ncamashi senkabazwe planethi futhi siye ohlangothini olufanayo. Yenza revolution ephelele emahoreni ambalwa. Mhlawumbe, zihlotshaniswa Uranus izindandatho. Iningi Kwatholakala 1986 ngumuntu mkhathi Voyager 2. Wenza izithombe Oberon, u-40% ubuso bayo. 25% kuphela kubo angayinikeza yangokwesiko umonakalo omkhulu kakhulu.

Impendulo yombuzo ophathelene nokuthi, e-satellite Oberon iplanethi sika, abafundi abaningi namuhla. Lomlomo waso senzeka ngoJanuwari 1787 by William Herschel. Nokho iminyaka engu-50 abantu abambalwa kakhulu ukwazi ukubona inyanga, ngaphandle usosayensi. Telescope sikhathi akazange ihluke yamandla aphezulu okungena ekujuleni. yokukhanya Modern ikuvumela ukuba ubone ngisho Oberon amateur isibonakude.

igama

Kuphela Uranus, iplanethi ne Oberon satellite, uqhosha nethimba "kaShakespeare". Umbhali umqondo ukuzoqhubekisela Shakespeare esibhakabhakeni baba sezinkanyezi, yebo eyiNgisi, Vilyam Gershel. Iplanethi kwatholakala ngengozi ngo-1781. Usosayensi wafuna ukuba alinike igama King George, kodwa isiko abahlulwa, futhi abazalwanga Uranus.

Ekuqaleni okuthiwa Oberon Uranus II. Kamuva, ezinye iziphuphutheki, noWilliam Lassell wababala ngokomlomo ibanga amaplanethi Kwatholakala, Uranus IV Oberon ithole igama. Kamuva, zonke okuphawulekayo ezidlula yaziwa ngebizo heroes kaShakespeare. I enkulu: Miranda, Ariyeli, Cordelia, Umbriel, Oberon futhi Ophelia.

isakhiwo

Ososayensi bakholelwa ukuthi Oberon, Uranus inyanga, kwakungase kubonakale lizale kudiski accretion. Yena ahaqa iplanethi ngemva nje lasungulwa. Ukwahlulela ngokubukeka isimo ebusweni kwenyanga, 'wayezelwe "e efanayo isikhathi njengoba ukuthi le planethi uqobo.

Kucatshangwa Ukwakheka satellite siqukethe amanani cishe alinganayo idwala amanzi, futhi iningi kangakanani ice. Lokhu kuboniswa kwabantu satellite - 1.63 g / cm. Omunye ungacabanga ukuthi engaba oyinhloko 480 km. Isakhiwo simiswe ngalendlela lelandzelako:

• core enamadwala;
• mhlawumbe ungqimba okusamanzi;
• isiphuku ezineqhwa.

incazelo

It has a ebusweni abe luhlaza ngokubomvu. Kubonakala sengathi lokhu kuwumphumela emiphumeleni isikhala weathering. Lokhu kwaba ngumphumela asebenzayo esigamekweni sokuqhunyiswa micrometeorites futhi icala zesandulela ubuso bayo abangaphezu kwesigidi edlule. Umehluko ngamandla komthunzi cishe okubangelwa akretsiey (falling izinto phezu kobuso yasezulwini umzimba ezizungezile imvelo). Futhi ehola Nenkabazwe inceku licace. ububomvu wakhe omkhulu abelokhu ewenza kungenzeka kubangelwa sokulungisa izinhlayiya okwesikhashana ukusuka endaweni. umbala bluish fresh umkhiqizo (uma kuqhathaniswa) enomkhiqizo wokumbiwa phansi.

Oberon - engumngane, okuyinto oluthatha ngobukhulu ohlelweni kanye wesishiyagalolunye Uranus zesimiso sonozungezilanga. Izici:

• ubukhulu - 1523 km;
• isisindo - 3,014 X10 ²¹ kg;
• surface area - abayizigidi ezingu 7.3 amakhilomitha ^2;
• ivolumu - 1,849 cubic amakhilomitha;
• izinga lokushisa - -203 ...- 193 ° C;
• Ubuningi - 1.63 g / cm.

ebusweni eligcwele - isici esasenza Oberon inyanga. Sputnik ngokoqobo ayinakho isikhala khulula ngaphandle komgodi wentaba-mlilo. Inombolo yabo ayikwazi ukukhushulwa. Okuningi uphondo yamuva esikhundleni "izibazi" langaphambilini, zivela kusukela nokuqhuma kanye nemithelela ukusuka endaweni. nensada okunjalo asemigodini (ngaphezu kwanoma yimuphi omunye satellite) kubonisa umhlaba mdala kangakanani.

Into esemqoka eyaziwa ngokuthi imigodi yezintaba-mlilo futhi zigodi. "Shakespeare" indaba ephathwayo liyalondolozwa lapha. Asemigodini olukhulukazi ingxenye ebonakalayo:

• Othello - 114 km ububanzi.
• Lear - 126 km.
• Romeo - 159 km.
• Macbeth - 203 km.
• Hamlet - 206 km.

Kungase kube emikhulu, kodwa abawona etholakalayo kulolu cwaningo. Abaningi asemigodini babe imisebe egqamile eyinqaba. Ososayensi babonisa ukuthi lesi ekushayweni amanzi ayiqhwa - ice. phansi Dark lalingase lisho ezingcolile esidayisa amanzi, by Isifaniso ne maria enqunywa ngokuthwasa kwenyanga. Enye ukucabangela phansi asemigodini Ukufiphaza esekelwe yokuthi ngaphansi kwamanzi ice uqweqwe ngokufanele kugcwele mnyama umbala. Zigodi ingasaphathwa, waqopha - Mommur (537 amakhilomitha).

orbit

Oberon - satellite ine orbit 584.000 amakhilomitha. Yena njalo ijikiselwe uhlangothi planethi. Akuyona into engavamile zesimiso sonozungezilanga. inyanga yethu isihlobo uMhlaba endaweni efanayo, okuyinto ejwayelekile eziphuphuthekini ezinkulu. Ngenxa ukuphambuka encane evela kumbuthano futhi khona ukuthambekela bhé, lokhu ibanga zingahluka. Isikhathi esemkhathini kuvumelana kwesikhathi Ukujikeleza izinsuku nantathu nengxenye.

Ibanga (kusukela izinyanga ezinkulu) Oberon, iningi orbit sihamba ngaphandle kokuphazamisa Magnetosphere kule planethi. Indawo yayo yangaphandle echayeke solar wind. Kwandisa amandla nokuhlasela Uranus plasma izinhlayiya lincane kakhulu kunamanye iziphuphutheki, ngakho Oberon zibukeke alula kakhulu kunomoya 'abafowabo' abengeziwe.

Le ndiza yenkabazwe planethi cishe kuvumelana umzila wenyanga izinyanga lakhona elikhulu kunawo wonke. ushintsho kwesizini ka eside - eminyakeni 42. Ngamunye izinti ngowokuqala kufihlwe cishe isigamu sekhulu leminyaka ebumnyameni ke okufanayo lisiphathele ushushiso ilanga.

Uma eminyakeni engamashumi amane nambili, ngesikhathi sokulingana kwemini nobusuku, ilanga Umhlaba sidlula indiza elisenkabazwe ye-Uranus. Kuleli qophelo, kukhona okuhambisanayo Ukusabalala iziphuphutheki.
