Dahsoon Amalthea - moon Jupiter

Si aad u hesho Amalthea, bilowga Jupiter ee la search. Oo isagu wuxuu dhex dhaqdhaqaaqa koox ee Pisces , oo aan lahayn meel joogto ah waxa ku jira. meeraha Tani waa kala duwan yihiin baaxadda iyo dhalaalaysa ifiyo, sidaas oo meesha waa Jupiter ah oo cirka jooga, waxaad arki doontaa xiddig dhalaalaya ku saabsan asalka ah ee alaabta fainter.

Discovery iyo magaca

Amalthea - waa ugu dahsoon oo dhan bilaha cusubu ee Jupiter. Amalthea - satellite, helay in 1892 by Edward Emelsonom Barnandom in fiirinta Lick iyadoo xoqad-refractor. Waxay ahayd satellite finalka, la ogaado in ayadoo la eegayo muuqaalka, halkii habka sawir, sida qof kasta oo kale. Companion muddo dheer lahaa magac kuma sida horyaal ah waxaa loo bixiyey si fudud satellite shanaad ee Jupiter. Iyo ku dhowaad hal qarni ka dib, sannadkii 1976, waxa uu helay magaceedii - Amalthea. Waxa uu ahaa magaca riyo ah, kicin ilmaha Zeus (in caddooyinka Greek).

bilaha cusubu dhashaan Jupiter

Waqtigan xaadirka ah ma waxaa loo yaqaan Satellite sida badan ee Jupiter, laakiin saynisyahano rumaysanahay in ay jiraan ugu yaraan boqolaal. Si aad u taariikhda, waxay diiwaan 67, iyo sidoo kale baratay oo kaliya 63 ka mid ah shayga. All ee Satellite ee caalamka waxa loo qaybiyaa saddex qaybood oo ka mid ah "gallium", gudaha iyo dibadda, ugu weyn waxaa la odhan jiray ka dib markii ay geesiyaal qadiimiga ah. Jupiter la og yahay in ay leeyihiin tirada ugu badan ee Satellite, taasoo sharxaysa sababta ay "bilaha cusubu dhashaan" aad u badan oo soo socda, waxa uu, sida ay leedahay beer gravitational awood badan.

The dhinacyada ku Satellite ee Jupiter waa kuwo kala duwan. jirka iyaga dhexdoodii laga helay waa kuwo yar, dhexdhexaad ah oo waaweyn. The ugu weyn oo ugu caansan iyaga ka mid ah - afarta reer Galili satalayt: Ganymede, Europa, Io iyo Callisto helay Galileo Galilei ee 1610. satalayt Gallium hareereeyeen Jupiter ka dib markii ay formation, oo la sameeyey ee boodh iyo gaasaska ka.

group of Satellite ee meeraha Jupiter

Kooxdu waxay ka kooban tahay dibadda satalayt yar, kuwaas oo dhexroor kala duwan tahay 1 ilaa 170 km. Galaatiya ay yihiin kuwo ku taagay oo dhiiran tahay in dhulbaraha Jupiter. Xilligan la joogo, tirada walxaha 59 outgroup. satalayt The, kuwaas oo ku dhow inuu ku biiro caalamka ay weheliyaan Galaatiya ay Jupiter jihada wareeg, iyo satalayt ugu fog fog dhaqaaqin dhinaca ka soo horjeeda. By group gudaha waa satalayt ugu weyn, sida Amalthea, Adraseya, Métis iyo Phoebe.

caddaymaha jirka

"Moon" ayaa qaab ah aan joogto ahayn, waa elongate, jirka bean-qaabeeya, ay dhamaadka fiiqan faray in meeraha Jupiter. Amalthea - satellite gaar ah oo ku filan, wuxuu ka dhigaa kacaan hareeraha dhidibka iyo hareeraha Rafaa gaaska synchronously for 0.498 maalmood. dusha oo dhan "Moon" waxaa lixdii bilood la craters, qaar iyaga ka mid ah waxay leeyihiin cabbir weyn, sida Pan iyo Gaia (hadda kaliya labo ee Kuliyadda iyo labada craters oo la magacaabay, qaar kale oo weli qarsoon). Amalteya - satellite taas oo uu leeyahay ay magaca dhismeedka giraanta for haydh "caaro". giraanta sameeyay waxaa si tartiib ah sameeyay sputtering meteorites qurubyada la lakabka dusha ay.

Ciidamada of cuf on Amalthea waa mid aad u yar, sidaas Qurub ciidda iyo qashin si fudud u tagto dusha. Sputnik - shanaad ee size, labaad oo kaliya in ay "gallium", meeraha saddexaad Jupiter ka. cabbir toosan yihiin 250 in 146 iyo 128 km, siday u kala horreeyaan. Like satalayt badan, waxa ay si joogto ah ayaa wajahaya caalamka ee xisbiga isla. Amalteya - satellite oo shanqarta kulayl badan waxaa gubtay, qoraxda, laakiin tani ma aha natiijo ah oo geedi socodka ka mid ah waxa ay gudahood, iyo kulaylku sare ay sababtay shucaac Jupiter iyo eedeeyay Qurub. Seynisyahanno ay cufnaanta waxaa loo xisaabiyaa, waxa uu ahaa 0.9 ± 0.1 g / cm3. Iyada oo ku saleysan xajmiga iyo mass of Amalthea, on this salaysan waxaan soo gabagabeeyey in ee ugu weyn waxaa ka kooban yahay baraf biyood. Iyo barafka ma aha adag, iyo godadka, wada safay ee jirka ku sarkhaansan cuf.

Falanqaynta Spectral muujinaysaa jiritaanka xeryahooda baaruud iyo macdan biyuhu kala duwan. Seynisyahanno soo jeedinaya in Amalthea waxaa a asteriyoodh qabsaday hal mar ama la soo sameeyay at falagiisuu ka sii fog. Inta lagu guda jiro formation of Jupiter iyo Satellite ay kastana falagiisuu dhex this heerkulka gaadhay 800 ° C, iyo si fudud u baraf Amalthea ma waxaa u muuqan kari lahaa. Jiritaanka aad u adag si ay u sharxaan, satellite waa mid aad u weyn yihiin in la soo sameeyey siddo Planetary. Inta badan, Jupiter qabsaday ka baxsan. ifafaale la mid ah oo laga dheehan karo in maalin aan la ururta, iyo astiriyoodhada.

satellite midabaynta

Amalteya- (moon Jupiter) - mid ka mid ah dhowr ah oo uu "Moon", laakiin ugu dahsoon. Intaa waxaa dheer, ay coloration waa doonee badan "meeraha cas" Mars. saynisyahano Qaar ka mid ah waxay aaminsan yihiin in casaan midabka - natiijo ah oo baaruud ah deggan, oo waxaa lagu tuuraa meesha bannaan oo ka mid ah marno of Io (moon Jupiter, halkaas oo ay jiraan waxqabad Kobenhagen joogto ah). Qaar kale waxay aaminsan yihiin in ay tahay qarniga chlorine in magnesium, potassium iyo sodium, kaas oo ka kooban shaydi ah ee xabagta bir ah iyo foomka cado oo cas. Satellite ma aha oo dhan cas, waxaa sidoo kale laga helay dhibco cagaaran. cilmi qaarkood sheegayaan in sababta gaaska chlorine in, buuxinta meel bannaan oo waxba kama jiraan ah oo jidhka gudahood, taasoo keentay in barakacay ay dusha, oo waxay ku abuuraa si tartib ah cagaar ah.

cilmi

The shuut "Moon" Jupiter la sameeyey sanadkii 1979 diyaaradaha godu "Voyager -1" iyo "Voyadzher- 2" by toogashada this ee xogta spectrum infrared on hab heerkulka dusha sare ayaa la helay.

In sano ee 1996- 2000 qalab "Galileo" lagu sameeyey sawiro fiican (2,4km / pixel). Waxa uu u duulay ee la soo dhaafay Amalthea, xisaabi mass ee cadow ah in ay dhaqdhaqaaq u gaar ah.

In sano ee 2000- 2001 gaariga "Cassini" sharaxay falagiisuu ee Amalthea. In 2006, unugga "New Horizons" satellite dib-u qastiyey galay falagiisuu. Si kastaba ha ahaatee, aqoonta this kuma filna. Qubarada ayaa weli yaabban satalayt sida badan ee Jupiter? saldhigga boos Modern "Hubble" sii cilmi in search of satalayt cusub oo ka mid ah nidaamka qoraxda. Waxaan rajeynayaa, Almatei qarsoodiga ugu dhakhsaha badan lagu xallin doonaa.
