Okumangazayo Amalthea - inyanga kaJupiter

Ukuze uthole Amalthea, isiqalo Jupiter sika nge search. Enaka ngokusebenzisa umlaza ka Pisces , futhi ayinaso isikhundla unomphela kuwo. Leplanethi ezahlukene ngobukhulu futhi ngokukhazimulayo liphume, ngakho lapho kuyinto Jupiter esibhakabhakeni, uzophawula inkanyezi ekhanya on isizinda lezinto fainter.

Ukutholwa negama

Amalthea - iyona ongaqondakali kunayo yonke izinyanga Jupiter. Amalthea - satellite, ezatholakala ngo-1892 ngu-Edward Emelsonom Barnandom ku Lick Observatory nge isibonakude-refractor. Kwakuwusuku lokugcina satellite, Kutsho ezibukwayo observation, kunokuba enezithombe indlela, njengawo wonke umuntu. Companion isikhathi eside babengenalo igama njengephayona ngokuthi kuvele satellite wesihlanu Jupiter. Futhi cishe ngemva kweminyaka eyikhulu, ngo-1976, kube lethiwa - Amalthea. Kwakuwusuku igama imbuzi, ukukhulisa usana uZeyusi (e zamaGreki).

izinyanga kaJupiter

Njengamanje akwaziwa iziphuphutheki eziningi kanjani of Jupiter, kodwa ososayensi bakholelwa ukuthi kukhona okungenani amakhulu. Kuze kube manje, ayeloba 67, njengoba wafunda kahle 63 into kuphela. Zonke iziphuphutheki planethi uhlukaniswe izigaba ezintathu "gallium", ngaphakathi nangaphandle, enkulu kunazo zonke zibizwa heroes lasendulo. Jupiter waziwa ukuba inani elikhulu iziphuphutheki, echaza ukuthi kungani "izinyanga" eziningi kangaka eduze kwayo, njengoba unenkambu ezinamandla okudonsa izinto.

Ubukhulu of kumasathalayithi of Jupiter awafani. Phakathi kwabo, bathole lesi sidumbu mncane impela, aphakathi nendawo kanye ezinkulu. Umhlangano omkhulu kunayo yonke futhi edume kunazo them - ezine waseGalile iziphuphutheki: Ganymede, Europa, Io futhi Callisto sitholwe uGalileo Galilei e 1610. Gallium iziphuphutheki ezungezwe Jupiter ngemva lasungulwa, futhi kwamiswa khona othulini amagesi.

Iqembu satellites planethi Jupiter

Iqembu yangaphandle siqukethe iziphuphutheki encane, ogama ubukhulu kuyahlukahluka kusuka 1 kuya 170 km. omise yabo ngempela welulela futhi ithambekele ekwenzeni yenkabazwe Jupiter sika. Ngalesi sikhathi, inani lezinto 59 outgroup. I iziphuphutheki, okuyinto isondelene abahambayo iplanethi kanye ezungeza yabo kaJupiter Ukujikeleza isiqondiso, futhi iziphuphutheki ezikude kakhulu ezihambayo kolunye uhlangothi. Ngu iqembu kwangaphakathi kukhona kumasathalayithi ngobukhulu, ezifana Amalthea, Adraseya, Metis futhi uFibhi.

Ukucaciswa ngokomzimba

"Moon" ine ijamo okungajwayelekile, kuyinto elongate, umzimba emabhontjisi emise, ekupheleni lwayo olucijile iqondiswe iplanethi i-Jupiter. Amalthea - satellite esiyingqayizivele ngokwanele, wenza kwaba nombhikisho emhlabeni axis awo kanye emhlabeni giant igesi izinsuku synchronously ngoba 0.498. Yonke kobuso "Moon" ligcwele asemigodini, abanye kubo Ubukhulu elikhulu, ezifana Pan futhi Gaia (okwamanje ezimbili kuphela Faculty kanye asemigodini amabili abizwa, abanye be- engaziwa). Amalteya - satellite esesikhundleni yayo igama indandatho ngesakhiwo usongene "isicabucabu". I ring kwakheka kancane kancane ezakhiwe sputtering izinhlayiya emkhathini nge ubuso bayo ungqimba.

Amandla adonsela phansi phezu Amalthea lincane kakhulu, ngakho uthuli doti kalula ushiye ubuso bayo. Sputnik - lesihlanu ngobukhulu, yesibili "gallium", iplanethi sesithathu kusukela Jupiter. Ubukhulu Linear kukhona km 250 kuya-146 128, ngokulandelana. Thanda iziphuphutheki eziningi, njalo ebheke iplanethi iqembu elifanayo. Amalteya - satellite okuyinto Likhipha ukushisa ezingaphezu kuka ibusa okuvela elangeni, kodwa lokhu akuwona umphumela ezinye izinqubo ngaphakathi it, kanye Ukushisa yesibili kubangelwa emisebeni uJupiter icala izinhlayiya. Ososayensi kwabantu bayo ibalwa, kwaba 0.9 ± 0.1 g / cm3. Kususelwa usayizi mass Amalthea, ngesisekelo salokhu saphetha ngokuthi ayinhloko yakhiwa ice zamanzi. Futhi ice akuyona eliqinile, futhi izimbobo emazinyweni, baqoqene ndawonye emzimbeni ngaphansi kwethonya adonsela phansi.

ukuhlaziywa Spectral kubonisa ukuba khona kwe-sulphur compounds namaminerali ezihlukahlukene amanzi amaningi. Ososayensi basikisela ukuthi Amalthea is a elisemkhathini ethumba esisodwa noma sesakhiwe ngesikhathi orbit ezikude. Phakathi kumiswa uJupiter iziphuphutheki yayo ukulokho izinga lokushisa safinyelela 800 ° C, futhi iqhwa Amalthea wayengeke asonge izandla avele khona. Khona kanye ukuba khona kunzima ukuchaza, satellite likhulu kakhulu ukuthi zimiswe kusuka izindandatho kwamaplanethi. Cishe, Jupiter walithatha kusukela ngaphandle. imihlola Okufanayo kungabonakala nasemkhakheni usuku bethu lezinkanyezi ezinomsila kanye asteroyidi.

Umbala satellite

Amalteya- (inyanga Jupiter sika) - omunye ezimbalwa "Moon" yakhe, kodwa oluyimfihlakalo kunalo lonke. Ngaphezu kwalokho, coloration yayo kuba acebile ukwedlula "planethi ebomvu" Mars. Abanye ososayensi bakholelwa ukuthi umbala obomvu - kuwumphumela okunethezekile nesibabule, okungukufa okungukuthi yabalingisi esikhaleni mlilo of Io (kaJupiter inyanga, lapho kukhona njalo wentaba-mlilo umsebenzi). Abanye bakholelwa ukuthi kuyinto isizukulwane chlorine ukuze magnesium, i-potassium ne-sodium, okuyinto zimumethe i admixture yensimbi oxide bese bakha luhlaza obomvu. Isethelayithi akuyona yonke obomvu, futhi wathola izindawo eluhlaza. Ezinye izazi zisikisela ukuthi isizathu ukuthi igesi chlorine ayizwayo isikhala uyize ngaphakathi emzimbeni, okuholela abangenamakhaya ku ubuso bayo, futhi yakha indawo eluhlaza.

ucwaningo

Isibhamu okokuqala "Moon" Jupiter enziwa 1979 godu izindiza "Voyager -1" futhi "Voyadzher- 2" yilo sokudubula infrared idatha spectrum ku imodi lokushisa kwamanzi eyatholakala.

Eminyakeni 1996- 2000 kudivayisi "uGalileo" kuye wenzé izithombe ezingcono (2,4km / kwe-pixel). Wandizisa esidlule Amalthea, ukubala nesisindo se-ukuhluka e ukunyakaza kwabo.

Eminyakeni 2000- 2001 imoto "Cassini" kuchaza emzileni Amalthea. Ngo-2006, iyunithi "okusha Horizons" kabusha ukucacisa emzileni satellite. Nokho, lolu lwazi akwanele. Ososayensi namanje ngizibuza iziphuphutheki eziningi kanjani of Jupiter? Modern isikhala esiteshini "Hubble" uyaqhubeka ucwaningo kusesho satellites entsha yesimiso sethu sonozungezilanga. Siyethemba Almatei imfihlakalo maduze ingaxazululwa.
