Oberon, Uranus satellite: description

In kasta oo dhammaan horumarka ee sayniska iyo tiknoolajiyada, qaar badan oo qarsoon ee Cosmos sii joogi qarsoon Dadka. Daraasaddu waxay of jidhadhka samada, oo ay ku jiraan bilaha cusubu dhashaan oo ka mid ah meerayaasha nidaamka qoraxda, waxa uu la xidhiidhaa dhibaatooyin badan. Masaafo hana u oggolaan in ay iyaga ka fiirsan si faahfaahsan. Oberon, satellite ah ee meeraha Uranus ah, iyo sidoo kale kale oo uu "Saaxiibadayda" wali sugayaan markoodii in cilmi dhamaystiran.

story

Tirada guud ee satalayt Uranus gaadho 27 cutub. Waxay kala qaybsan yihiin kooxaha:

• gudaha;
• dibadda;
• ugu weyn.

"Ganaax" Gudaha 13 buurbuur madow ballaciisu yahay 50 ilaa 150 km. Kulligood waxay u iilan ku dhowaad sax ah on dhulbaraha ee caalamka oo isku jiho ah. Samee kacaanka dhamaystiran in dhowr saacadood. Waxaa laga yaabaa in, waxay ku xiran yihiin siddo Uranus. Inta badan laga helay 1986 by a pride Voyager 2. Waxa uu sidoo kale ka dhigay sawirada Oberon, oo ku saabsan 40% ka mid ah ay dusha. % Oo ka mid ah oo keliya 25 siiyo in sahamin.

Jawaabta su'aasha ah in, in meeraha ah ee satellite Oberon, arday badan ayaa maanta ogaan. Its furitaanka ka dhacay January 1787 by William Herschel. Weli muddo 50 sano ah dad aad u yar oo ay awoodaan si ay u arkaan dayaxa, saynisyahan ahayn. Telescopes in waqti is khilaafeen awood cabaar sare. optics Modern kuu ogolaanayaa inaad si aad u aragto xataa Oberon xoqad hiwaayadda.

magaca

Kaliya Uranus, meeraha la Oberon satellite ah, faanaa ah "Shakespeare ee" ambabaxay. Qoraaga of fikradda ah in sii hurin Shakespeare Samada noqday astronomer ah, dabcan England, Vilyam Gershel. Meeraha ayaa la ogaaday by fursad in 1781. saynisyahan waxa uu doonayay inuu siiyo magaca King George, laakiin dhaqan adkaaday, oo waxaa u dhashay Uranus.

Asal ahaan u bixiyey Oberon Uranus II. Later, satalayt kale, iyo William Lassell iyagii u tiriyey sidii masaafada u dhaw quraxda xidiga ah laga helay, Uranus IV Oberon helay magaca. Later, oo dhan muhiim ah in magnitude noqday kuwa loo yaqaan by magaca geesiyaal ah Shakespeare. ugu weyn ee The: Miranda, Ariel, Cordelia, Umbriel, Oberon iyo Ophelia.

Qaab-dhismeedka

Qubarada badankooda ayaa aaminsan Oberon, Uranus moon, waxaa lagu aasaasay laga yaabaa inay ka disk accretion ah. Wuxuu hareereeyeen caalamka ka dib markii ay formation. Siidi by gobolka dusha moon ee, uu "u dhashay" in muddada waqtiga la mid ah sida in of meeraha laftiisa.

Ajnabiga satellite Halabuurka ka kooban yahay xaddi qiyaas ahaan siman dhagaxa iyo biyaha, iyo ugu waa ka baraf. Tan waxaa lagu tilmaamay by cufnaanta satellite ah - 1.63 g / cm. Mid ka mid ah u qaadan karnaa in gacan muhiimka ah waa 480 km. Dhismaha waa sida soo socota:

• core dhagax;
• suurto gal ah lakabka ah ee dareeraha ah,
• go'iisii baraf.

Waxay leedahay dusha ka mid ah cado iyo guduud ah. In suurtagalnimada oo dhan, tani waa natiijada ka soo saamaynta cimilada bannaan. Tani waxa ay ahayd natiijada ah micrometeorites qaraxii firfircoon oo qayb ka mid ah ay dusha lagu eedeeyay in ka badan hal milyan oo sano ka hor. Farqiga in xoogga hadh waxa laga yaabaa inay sababtay akretsiey (dhicidda walxaha on dusha sare ee deegaanka Falag buu jidhka ku xeeran). Oo Safra addoon horseedka u ifaya. Uu casaan u daran waxaa laga yaabaa in ay sabab u saldhigan ee Qurub ganaax ka bannaan. midab buluug ah wax soo saarka (xad) kayd macdanta cusub.

Oberon - Saaxiibkiis, oo degan labaad ee ugu weyn ee nidaamka iyo sagaalaad ee Uranus nidaamka qoraxda. Features:

• dhexroor - 1523 km,
• miisaanka - 3,014 X10 ²¹ kg,
• bedka - 7.3 million kiiloomitir ^2;
• mugga - 1,849 bilyan oo kiiloomitir cubic;
• heerkulka dusha - -203 ...- 193 ° C,
• Mugga - 1.63 g / cm.

dusha ugu badneed - feature a kala duwan ee moon Oberon. Sputnik macno leedahay meel ma xor ah oo aan bohol ah. Tiradooda lama kordhin karo. masaf dhawaan More bedelay "nabarradii" hore, waxay u muuqataa ka Mandheera iyo saamaynta ka bannaan. tiro badan oo noocan oo kale ah ee craters (in ka badan satellite kasta oo kale) waxay muujinaysaa in ay da '.

shayga ugu weyn ee loo yaqaan craters oo canyons. "Shakespeare" theme halkan sii raagayaan. The craters ugu weyn on qayb ka mid ah la arki karo:

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

Waxaa laga yaabaa weyn, laakiinse iyagu ma ayaa diyaar u ah daraasadda. Qaar badan oo ka craters leeyihiin rays dhalaalaya hanti. Seynisyahanno soo jeedinaya in warshadu hawada this oo biyo ah la qaboojiyey - baraf. hoose Dark ayaa tilmaamaya laga yaabaa in outlet biyo wasakh ah, isu ekaysiinta la Maria dayaxa. Kale malo craters hoose ka fujiyaan ku saleysan xaqiiqda ah in ka yar dusha barafka qolof u amro midabka geyi-madow. Canyons badan ka yar, ugu dheer - Mommur (537 kilometers).

idiinna

Oberon - satellite uu leeyahay kastana falagiisuu dhex 584.000 kiiloomitir. Waxa uu si joogto ah waa wareejiyo si ay hal dhinac oo meeraha. Ma aha wax aan caadi ahayn in nidaamka qoraxda. moon Our qaraabo in Earth ee meel la mid ah, taas oo ah caadiga ah ee Satellite waaweyn. Sababo la weecasho yar ka goobada iyo rabitaan joogitaanka Equatorial ah, fogaanta this kala duwanaan karaan. Muddada orbital ku beegan tahay muddo wareeg maalmaha iyo toban iyo badh ah.

fog The (ka bilaha cusubu dhashaan weyn) Oberon, inta badan ay kastana falagiisuu dhex maraa oo aan saamayn ku magnetosphere meeraha ee. Its dusha dibadda ah la kulmin dabayl qoraxda. Kordhiyaa awooda weerarka by qayb plasma Uranus waa uga yar yahay satalayt kale, si Oberon aragga xumbo ay "walaalo".

Diyaaradan ayaa Dhulbadhaha ee caalamka si qallafsan la kulmeen ka Galaatiya ee bilaha cusubu dhashaan ay ugu weyn. isbedel xilliyeed ee mudada dheer - 42 sano. Mid kasta oo ka mid ah ulaha ku dhow nus qarni ugu horeysay qarsoon a mugdi ah, ka dibna isku haya ee qorraxda.

Marka laba iyo afartan sannadood, inta lagu guda jiro maailnta ah, Qorraxda iyo dhulka maraa diyaarada Equatorial ee Uranus. Halkaa marka ay marayso, waxaa jira Satellite-imaad is dhaafsi.
