Uyini iplanethi ezikude kakhulu esimisweni sonozungezilanga?

Ngaphezu Umhlaba, kukhona esimisweni sonozungezilanga, kwenye iplanethi blue - Neptune. Ngo-1846 kwatholakala sibonga izibalo zezibalo kunokuba observation.

Uyini iplanethi ezikude kakhulu esimisweni sonozungezilanga eLangeni?

Ngo-1930, i-Pluto wavulwa. Kuze 2006, sasibhekwa zinyanga iplanethi lesishiyagalolunye zesimiso sonozungezilanga. Nakuba Neptune - kuphela lesishiyagalombili. Nokho, ngo-2006 i-International Astronomical Union elinikwe nencazelo entsha kwegama elithi 'iplanethi' Pluto kayiwanga ngaphansi kwazo. Kukhona izinguqulo ngisho ukuthi akakholelwa basonta isimiso sethu sikanozungezilanga, futhi liyingxenye Kuiper Belt.

Futhi, lesi sihloko, yena waba bancishwa kusukela ngo-1979 kuya ku-1999, ngalesi sikhathi, i-Pluto esengaphakathi emzileni iplanethi Neptune.

Ngakho-ke, umbuzo: "Ubani iplanethi ezikude kakhulu yesimiso sonozungezilanga" - ungezwakala njengempendulo amagama amabili.

Neptune in izinganekwane Roman iyona unkulunkulu kolwandle.

ukutholakala

Ngokusemthethweni iplanethi ezikude kakhulu esimisweni sethu sonozungezilanga - Neptune - latholakala 1846. Nokho, ngo-1612-ke kwachazwa uGalileo. Kodwa wabe kubhekwe wakhe inkanyezi esinqunyiwe, kungani hhayi obonwa owathola yayo.

Ukuba khona iplanethi entsha ezalwe 1821, lapho izinguquko idatha ku emzileni Uranus yashicilelwa, okuyinto zazihlukile amagugu ethebuleni.

Kodwa kuphela orbit Septhemba 23, 1846, ngemva kwezinyanga ezimbili zokufuna, ngokusebenzisa izibalo Neptune kwatholakala.

Igama lakhe wathola ngoba wezibalo, eyivula (W. Leaver), okunguyena kwasekuqaleni wafuna igama iplanethi ngemva yena.

Uyini iplanethi ezikude kakhulu esimisweni sonozungezilanga? incazelo

Neptune ngokuqhubekayo bacwiliswa ukuhwalala. ukukhanya kwalo lingaphansi izikhathi 900 kunalokho kule planethi yethu. Sun kusukela orbit kubonakala nje inkanyezi ekhanya kakhulu.

Kuyinto giant at ibanga 4,55 bhiliyoni amakhilomitha, noma engu-30. . E inobungako 17,15 kunangendlela Earth ububanzi izikhathi - izikhathi 4 ngaphezulu. inhlanganiso kwesilinganiso sayo izikhathi nengxenye kuphela izinkomba yamanzi (1.6 g / cu. Cm). Ngakho, Neptune libhekisela eqenjini amaplanethi amakhulukazi, okuyinto sihlanganisa Saturn, i-Jupiter ne-Uranus.

Iplanethi ezikude esimisweni sonozungezilanga ubizwa nangokuthi ice, ngoba mass ane-helium ne-hydrogen ngezithako zawo akuyona ezingaphezu kuka 15-20%.

Njengezinye imidondoshiya, Neptune ngesivinini okukhulu osebenzisa kuma-axis awo. Usuku lwakhe amahora 16,11 kuphela. Uzungeza ilanga, wenza uguquko orbit ucishe ube isiyingi zeminyaka 164,8. Ngo-2011 waphothula ayenawo kuqala ngokugcwele kusukela ukuvulwa.

Phezu kobuso Neptune imimoya enamandla anqobe, ngejubane isilinganiso zazo - 400 m / umzuzwana.

Ngokuthakazelisayo, izinga lokushisa kule planethi kuyinto - 214 C lapho ukuba ephansi kakhulu. Kuyaziwa ukuthi iningi iplanethi ezikude system elanga has siqu lwaluvelaphi ukushisa ngaphakathi, ngoba izikhathi 2.7 amandla afike akhanye khona emkhathini kuka bumunca ukusuka elangeni.

Emhlabeni njalo kwenzekani ushintsho zonyaka. Omunye isizini ihlala iminyaka engaba ngu-40.

iziphuphutheki

Iplanethi ezikude esimisweni sonozungezilanga has 14 iziphuphutheki. Babevame zihlukaniswe amaqembu amathathu:

- langaphakathi: Talas, Naiad, Galatea, Despina, Larissa, Proteus;

- eceleni ukwaba Nereid futhi Triton;

- iziphuphutheki ezinhlanu angaphandle abanalo igama.

Isigaba sokuqala sihlanganisa Clumps amnyama ukufinyelela 100-200 km nokuba i ijamo okungajwayelekile. Bona uphendukisa endaweni orbit isiyingi cishe yenkabazwe. Zindiza emhlabeni ngamahora ambalwa nje.

Isigaba sesibili sihlanganisa Triton. Lena satellite kahle esikhulu. Ubukhulu bayo - mayelana 2,700 km, imali ingqikithi emhlabeni Neptune lenzani izinsuku 6. Lemiklamo, kancane esondela iplanethi. Uma hits Neptune futhi ngaphansi kwethonya amabutho olwandle aphendukele kwesinye indandatho. Indawo yayo kubanda, kunenkolelo ngaphansi uqweqwe ice zineminyaka ulwandle.

Nereid ujikeleza giant izinsuku 360. It has an ijamo okungajwayelekile.

iziphuphutheki bangaphandle kude kakhulu (amashumi ezigidi amakhilomitha) kusukela Neptune. izimpukane Iningi esikude emhlabeni wonke iminyaka engu-25. Uma ucabangela orbit yabo ukuthambekela indiza enkabazwe kanye nokunyakaza reverse, kwanqunywa ukuthi bathunjwa by Neptune ku Kuiper ibhande izinto.

satellite zokugcina lavulwa ngo-July 2013.

Neptune has izindandatho ezinhlanu izinhlayiya zeqhwa. Ezinye zazo akhiwa carbon, ukuze Zikhiphela abomvu. Bona abhekwa ngokulinganiswa ayemncane futhi ibingaba eyesikhashana ngempela. Amasongo Neptune engazinzile nokunye sihluke nomunye.

amaqiniso ezithakazelisayo

Ukuphendula umbuzo mayelana nendlela amaplanethi ezikude sonozungezilanga eyaziwa mkhathi "Voyazhder 2" wethulwa, kungashiwo ukuthi ekuqaleni wathunyelwa ukufunda uJupiter Saturn, kodwa indlela usezuze njengoba Uranus ne-Neptune. It wethulwa 1977.

Agasti 24, 1989, wahamba ngebhanoyi e 48 eziyinkulungwane. Km Neptune. Ngalesi sikhathi, i-Earth bathunyelwa izithombe planethi satellite yayo Triton.

Ngo-2016 kwakuhlelwe ukuthumela kwenye mkhathi iplanethi. Nokho, okwamanje ngqo kwethulwa usuku akuyona.
