Uranus - iplanethi enomoya. Izici and izici iplanethi

Uranus - iplanethi enomoya esimisweni sonozungezilanga, kodwa lithi akufanele ezikude kakhulu elangeni. Lokhu giant kwatholakala ekhulwini XVIII. Ubani eyivula, futhi yiziphi suputniki Uranus? Yini ekhethekile ngale kule planethi? Incazelo iplanethi Uranus, ukufunda lesi sihloko ngezansi.

Izici

Lona iplanethi lwesikhombisa eLangeni ibanga. Ububanzi it is the lwesithathu, kuyinto 50 724 km. Ngokuthakazelisayo, ubukhulu Uranus obukhulu kunobukaJohane Neptune, at 1840 km, kodwa nenqwaba Uranus ingaphansi, okuyinto usibeka endaweni yesine phakathi heavyweights sonozungezilanga.

Iplanethi enomoya ebonakalayo ngokubona okubonakala ngeso lenyama, kodwa isibonakude nokwanda kwentshiseko ngekhulu kuzovumela wakhe ukubona kangcono. Suputniki Uranus cabanga nzinyana. Linani selilonkhe lebantfu labange-27, kodwa zikude emhlabeni futhi dimmer okuningi kunalokho.

Uranium ingenye igesi imidondoshiya ezine, futhi kanye Neptune yakha ahlukene iqembu ice imidondoshiya. Ngokusho ososayensi, amaplanethi igesi giant owasungula ngisemncane kakhulu, eziyingxenye nakho kukodwa.

Ukutholakala Uranus

Ngenxa yokuthi kungabonwa esibhakabhakeni ngaphandle amathuluzi okubona, Uranus ngokuvamile kuba iphutha ngoba inkanyezi dim. Ngaphambi ukuthi uchaze ukuthi kuyinto iplanethi, kwathiwa ebonwe esibhakabhakeni izikhathi 21. Okokuqala yambona John Flemsid e 1690, lubalwa inkanyezi kule nombolo 34 e umlaza ka Taurus.

Owathola Uranus Vilyam Gershel kubhekwe. Mashi 13, 1781 ebona izinkanyezi kwesibonakude ezenziwe umuntu, okusikisela ukuthi Uranus - inkanyezi enomsila noma hazy. Ezincwadini zakhe ngokuphindaphindiwe laveza ukuthi wabona inkanyezi enomsila ngoMashi 13.

Izindaba umzimba omusha yasezulwini ukubonwa masinyane zihlakazeke emibuthanweni ngokwesayensi. Lomunye umuntfu wake watsi kwaba enomsila, nakuba abanye ososayensi sokungabaza. Ngo 1783, Uilyam Gershel yamemezela ukuthi iplanethi namanje.

iplanethi okusha wakhetha ukunika igama behlonipha kankulunkulu wamaGreki Uranus. Zonke kwamanye amaplanethi zithathwa asuselwa ezinganekwaneni Roman, futhi kuphela igama Uranus - kusukela esiGrekini.

Ukwakheka kanye nezici

Uranus kukhulu kunenani izikhathi Umhlaba 14.5. Iplanethi enomoya esimisweni sonozungezilanga engazazi kithi eqinile. Kusolwa ukuthi liqukethe core kanzima eliqinile kancane kancane, ice camera. Isendlalelo phezulu emkhathini.

Ice igobolondo Uranus Akunzima. Siqukethe amanzi, i-methane ne-ammonia, futhi ngu-60% emhlabeni. Ngenxa ukungabikho ungqimba okuqinile ube nobunzima ekutholeni Uranus emkhathini. Ngakho-ke, cabanga zangaphandle emkhathini igesi ungqimba.

Lokhu igobolondo le planethi uba nombala oluhlaza ngenxa i-methane, olubamba imisebe ebomvu. Uranus yakhe% 2 kuphela. Amagesi ezisele, okuyinto singene Ukwakheka asemkhathini - kuyinto helium (15%) ne-hydrogen (83%).

Njengo-Saturn, i-iplanethi enomoya has izindandatho. Kodwa iye yakha esanda kutholakala. Kukhona kucatshangwa ukuthi leso sikhathi izinyanga Uranus, okuyinto ihlukaniselwe izinhlayiya ezincane eziningi. Sekukonke kukhona 13 izindandatho, iringi yangaphandle has a ilambu elikuhlaza, kulandele elibomvu, kanti bonke abanye babe grey.

Le nhlangano yenkolo yokulwela uzungeza emzileni

Iplanethi enomoya esimisweni sonozungezilanga kusukela Earth 2.8 bhiliyoni amakhilomitha. Yenkabazwe ka Uranus esitshekile ukuba nomjikelezo wawo, ngakho Ukujikeleza planethi cishe "uqamba amanga" - nendawo. Njengoba uma omkhulu igesi-ice ibhola Rolls azungeze inkanyezi yethu.

Planet uzungeza ilanga uphendulela iminyaka 84, futhi osukwini lwayo ukukhanya sithatha amahora mayelana 17. Imini nobusuku esikhundleni ngokushesha kuphela enkabazwe band ewumngcingo. Kwezinye izingxenye zomhlaba '42 usuku lokugcina, bese okufanayo - ebusuku.

With eside ushintsho ngesikhathi esinjalo sokwenziwa kwezinto ngosuku bazitshela ukuthi umehluko lokushisa kufanele kube ngokwanele ezinzima. Nokho, endaweni wawushisa kunayo yonke eyaziwayo Uranus - kungcono yenkabazwe kunokuba izigxobo (ngisho zikhanyiswa ilanga).

Isimo sokukhululeka ngokwenkolo Uranus

Njengoba sekushiwo, Uranus - iplanethi kubanda, nakuba Neptune futhi Pluto zitholakala kakhulu ezikude ilanga. lokushisa yalo ephansi impela ifinyelela -224 degrees ngokwesilinganiso emoyeni ungqimba.

I abacwaningi baye baqaphela ukuthi Uranus libhekene izinguquko ezithile zonyaka. Ngo-2006, it laligujwa kanye izithombe kumiswa vortex asemkhathini at Uranus. Ososayensi sebeqala nje ukufunda ushintsho zonyaka emhlabeni.

Kuyaziwa ukuthi kukhona amafu phezu Uranus nomoya ezaziwayo. Nge indlela zezingongolo igcine isivinini incipha. ngesivinini esiphezulu umoya iplanethi kwaba ngu-240 m / s. Ngo-2004, kushintsha isimo sezulu sabhalwa ngo-March kuya May: anda isivinini somoya, isiphepho siqalile, namafu wabonakala kaningi.

Ukwabela zonyaka enjalo emhlabeni: eseningizimu ngenjikalanga ehlobo, esenyakatho entwasahlobo ngesikhathi sokulingana kwemini nobusuku kanye enyakatho ngenjikalanga ehlobo.

Magnetosphere nokuhlola kwamaplanethi

Mkhathi kuphela osekuzuziwe Uranus - kuyinto "Voyager 2". Kwakuthinta ngu NASA umkhankaso ngo-1977 ngokuqondile ukufunda amaplanethi ezikude yesimiso sethu sonozungezilanga.

"Voyager 2" wakwazi ukuthola ezintsha, indandatho ngaphambilini ongabonakali Uranus, ukufunda oyiyo, kanye nesimo sezulu. Kuze kube manje, eziningi namaqiniso aziwayo ngalokhu iplanethi kusekelwe idatha etholwe nale kulandzelana nekuhlunga tinsita.

"Voyager 2" futhi wathola ukuthi iplanethi enomoya has a Magnetosphere. Kwaphawulwa ukuthi amandla kazibuthe iplanethi akuveli isikhungo salo weJiyomethri. It is esitshekile by 59 degrees kusuka eksisi ujikeleza.

Lezi idatha abonisa ukuthi amandla kazibuthe Uranus azilingani, ngokungafani umhlaba. Kukhona kucatshangwa ukuthi lokhu kuwuphawu ice amaplanethi, kusukela yesibili ice giant - Neptune - Ubuye inkambu quin kazibuthe.
