Iplanethi yeNeptune ngokwezifundo eziye zaqoshwa ekubonweni kwendawo yonke iwumhlaba wesishiyagalombili futhi ingeyokugcina ohlelweni sonozungezilanga. Kuyiplanethi lapho ongoti abaningi bezibuza khona kuze kube muva nje:ineptune inezinyanga ezingaki?, okubonisa ngokulandelayo ukuthi ngokungafani neplanethi yethu (uMhlaba), inezingaphezu kweshumi. Ngakolunye uhlangothi, iNeptune izungeza iLanga eminyakeni eyi-164 izinsuku ezingama-323 amahora angama-21,7 kanti usuku luyi-16H 6.6 min.
Imvelo yayo ishesha kakhulu futhi ngenxa yalokho ihlanzeke kakhulu njengoba kunomoya ovunguzayo njalo esimiso sonozungezilanga (kufika ku-1600 km/h), kodwa imimoya yayo yenziwe nge-hydrogen, Helio futhi i-methane ilula kangangokuthi ngeke ibe umoya ogwini lolwandle. Nokho, izivunguvungu ezinkulu ziye zapheleliswa kuleyo ndawo.
INeptune inezinyanga ezingaki?
Isistimu yesathelayithi ephethwe yi- iplanethi neptune Lokhu kuyadida, njengoba izinyanga zayo eziningi zingase zibe yi-extrasolar. Lokhu kwenza kube yinto ethokozisayo yokufunda emkhakheni we isayensi yezinkanyezi.
Ngakolunye uhlangothi, ngaso sonke isikhathi lapho abathandi bezinkanyezi abaningi kangaka kanye nososayensi ngamunye abafunda le sayensi bezibuza: INeptune inezinyanga ezingaki? Futhi ngokwemiphumela etholiwe, kwatholakala ukuthi leli qiniso lingase lincike ezintweni ezitholakala kuleyo ndawo, okungukuthi, lingase lincike ku-Kuiper Belt, lapho izinto eziningi zivame ukuzungeza, noma nje ngomphumela wokushayisana phakathi. imihlaba, ekhiqiza izinto eziphilayo eziba yiqhwa okuthi ekugcineni isimo sazo kube yinkanyezi enomsila.
Manje, uma sicacisa kabanzi ngocwaningo lwezinyanga zale planethi, singabona ukuthi yilokhu okwenzeka ngenyanga enkulu kunazo zonke ye-Neptune (Triton) njengoba ama-akhawunti ahlukene okuhlangenwe nakho kwesayensi atshela ukuthi ukuzungeza kwalesi sathelayithi nakho kungaletha uguquko olungashintsha ingqikithi yenyanga ngayinye yalelizwe. Ukujula esihlokweni, kuyathakazelisa ukwazi izici ze-neptune.
Ukutholwa kweplanethi iNeptune
Okokuqala Isathelayithi yeNeptune Yatholwa usosayensi uWilliam Lassell ngonyaka ka-1846 futhi okwamanje yaziwa ngokuthi i-Triton, ezinsukwini ezingu-17 ngemva kokwambulwa kweNeptune. Azikho ezinye izinyanga zaseNeptune ezabonakala kwaze kwaba ngu-1949, lapho usosayensi uGerard Kuiper ethola uNereid. Lezi zinyanga ezimbili ze-Neptune zembulwa kuphela kuze kufike i-Voyager 2 ngo-1989, lapho amasathelayithi amasha ayisithupha abonakala esifundeni esiseduze ne-Neptune.
Kulokhu, ngo-2013, kwabikwa ukutholakala kwenyanga ye-14, ephakathi kuka-Larisa ne-Proteus, futhi yaqokwa okwesikhashana 'S/2004 N1' kusalindwe ukunikezwa kwegama-mbumbulu eliqondile. Lokhu okutholakele kungeza ohlwini olude lwe iziphuphutheki zemvelo azungeza amanye amaplanethi ohlelweni sonozungezilanga.
abhalisiwe njengamanje Izinyanga eziyi-14 emhlabeni iNeptune, lezi izi:
Naiad
Yinyanga eseduze kakhulu ne-Neptune, evezwe ngo-1989.
thalase
Kuyisethelayithi yesibili ye-Neptune, edalulwe ngo-1989.
I-Despina
Le nyanga ekhangayo yatholakala ngonyaka ka-1989 futhi ibhalwe njengeyesithathu kule planethi.
IGalatea
Yinyanga yesine ye-Neptune, ebonakaliswa ngo-1989.
ULarisa
Yinyanga yesihlanu ye-Neptune, emangazwe u-Reitsema, u-Hubbard, u-Lebofsky kanye no-Tholen ekuhlanganiseni izinkanyezi kwe-Neptune.
I-Proteus
Yinyanga yesithupha kaNeptune, evezwe ngo-1989 nguSynnott noSmith.
Triton
Besivele sikhuluma ngale nyanga ethile, njengoba iyindikimba enkulu kunazo zonke iNeptune enazo. Ngakolunye uhlangothi, ngokwenani layo eliphezulu le-nitrogen, I-Triton iba inyanga ebanda kunazo zonke kwakho konke. Ubuso bayo bukhipha ukukhanya okungaba ngu-70% kuyilapho kucwiliswa ukukhanya okuncane okubanda kakhulu. Kulolu hlelo lwemibono, kuphinde kuvezwe ukuthi ngaphezu kokuba ne-nitrogen, le nyanga ine-methane ne-ammonia. Ukuze uthole ukuhlaziya okuningiliziwe, kuyasiza ukuqhathanisa lolu lwazi nolwamanye amaplanethi afana Saturn.
Imigqa emnyama evezwa kweminye imifanekiso ibonakala inikezwa izintaba-mlilo ezithile ezincane ezineqhwa le-nitrogen elixutshwe nezinto eziphilayo ezikhishwa ama-geyers enyanga i-Triton.
Nereida
Kuyisathelayithi yesishiyagalombili yeNeptune, evezwe ngo-1949 nguGerard Kuiper.
halimede
I-Neptune inezinhlobo eziningi zezinyanga futhi i-Halimamede ayisekho kude kakhulu, ngokuphathelene nerekhodi yenani lamasathelayithi i-Neptune enawo, lokhu kwatholakala ngo-2002 futhi ingeyesishiyagalolunye kuze kube manje.
Sao
Ngokwale akhawunti yokuhlukaniswa kwezinyanga i-Neptune enayo, sifinyelele endaweni engu-10, lokhu ngokungangabazeki kuhlala i-Sao, isathelayithi eyatholwa ngo-2002.
I-Laomedeia
Ngokufanayo, kukhona iLaomedeia. Kutholwe ngendlela efanayo ngonyaka iSao etholwe ngawo.
valelisa
I-Psámate ibalwa kunombolo 12 futhi itholwe nguSheppard.
neze
Manje sekuyithuba likaNeso. Lokhu ngokungangabazeki kuhlanganisa inombolo ye-13 futhi yatholakala ngemuva kweqembu likaMateo J. Holman.
S/2004 No. 1
Ekugcineni sifika ku-S/2004 N 1 eyabhaliswa kungekudala, kangangoba namanje ayinalo igama eliqondile. Kodwa-ke, ucwaningo luyenziwa okwamanje, olubonisa ubudlelwano obuthile neplanethi yethu futhi lunikeza izimpendulo ezengeziwe embuzweni ineptune inezinyanga ezingaki.
Ukunemba kakhudlwana futhi sibuyela emlandweni wesayensi yezinkanyezi, ngonyaka ka-1989, kwase kuphethwe ngokuthi iplanethi yethu yenkanyezi yanamuhla inezinyanga eziyi-13 kuphela. Kodwa-ke, ngokuhamba kweminyaka kwatholakala ukuthi lokhu kwakungalungile ngokuphelele njengoba umzimba omusha wabonwa eNeptune.
Kulapha lapho ngemva kochungechunge lwezifundo, i-S/2004 N 1 yavela, noma kunalokho, yatholwa, inyanga ecatshangwa ukuthi iyinombolo 14 ohlwini olude lwamasathelayithi le planethi enkulu enawo. Izithombe ezimelwe kahle kakhulu zalesi sathelayithi zithathwe ngabakwa isibonakude sesikhala esixobayo phakathi kuka-2004 no-2009.
Bekucatshangelwa ukuthi i-S/2004 N 1 ayizange ivele kunoma yisiphi isithombe ngokuhamba kwesikhathi, nakuba kuze kube manje akwaziwa ukuthi yini ngempela ethathwe yisibonakude. Kodwa-ke, lokhu kuyangabazeka okwamanje njengoba ngemuva kokufunda kakhulu le nyanga entsha, ibonakale imnyama kakhulu. Esithombeni esiphambene ungabona ngaphandle, i-reactionary ne-orbithi ehlukile yenyanga enkulukazi ye-Neptune, i-Triton.
Ake sicabange ukuthi i-Triton yathathwa ku-Kuiper Belt ngemva kwesikhathi eside kunohlelo lwesathelayithi oluyingqayizivele lwe-Neptune olwadalwa. Ukuzungeza kwezinyanga ezedlule kuphazanyiswe yilo mcimbi wasemkhathini, okuholele ekukhishweni kwezinye izinyanga nokucekeleka phansi kokushayisana kwezinye izinyanga. Ukuze ufunde kabanzi mayelana nokwakheka kwesimiso sonozungezilanga kanye nobudlelwano baso ne-Neptune, vakashela lesi sihloko ukwakheka kwesimiso sonozungezilanga.
Ngakho-ke, i-S/2004 N 1 iyingxenye yesimiso esiyingqayizivele sezinyanga, njengoba ifanisa nezinye iziphuphutheki eziseduze zeNeptune namathoni etiyela. I-Diffusion iyinikeze indawo engaba ngu-16 kuya ku-20 km, okuyenza ibe inyanga encane kunazo zonke e-Neptune, ngo-2013. Isizinda esibi sincane ukuze sifane nama-molecule akhona endaweni, kodwa iqhwa lamanzi likhulu ohlelweni sonozungezilanga olungaphandle, kucatshangwa ukuthi hambisana ne-S/2004 N 1.
Okokugcina, kubalulekile ukuqaphela ukuthi iNeptune isibe enye yeplanethi enkulu kunazo zonke ohlelweni lwethu sonozungezilanga, futhi iletha ukuthi ngenxa yobukhulu bayo obusabekayo, ingakwazi ukuhlalisa inani lezinyanga ezingu-14, iphendule lokho abantu abaningi abavame ukuzibuza, INeptune inezinyanga ezingaki?.
