Kusukela ngo-Agasti 24, 2006, i-Pluto yehla esigabeni sayo seplanethi esimisweni sethu sonozungezilanga futhi yaba iplanethi encane, yayeka ukuba ngowesishiyagalolunye ezindikimbeni zasemkhathini. yenzaKungani i-Pluto ingeyona iplanethi?? Ukukuchaza kangcono lokhu, sikumema ukuthi ufunde lesi sihloko futhi uthole ukuthi kwenzekani kuPluto.
Iplanethi X
Kufanele sibuyele emuva phakathi nekhulu leshumi nesishiyagalolunye, lapho isazi sezinkanyezi u-Urbain Le Verrier ekwazile ukubikezela indawo yeplanethi i-Neptune, ngokusekelwe kokunye okungahambi kahle kanye nokuphazamiseka okungase kubhekwe emhlabeni i-Uranus. Esikhathini esilandelayo, ososayensi baphetha ngokuthi isizathu sokuphazamiseka okuphawuliwe kungaba khona enye iplanethi eyayinethonya elithile emzileni we-Uranus futhi bayibhapathiza ngegama lePlanethi X.
Percival Lowell 1904
Ngasekupheleni kwekhulu le-1894, usosayensi uPercival Lowell wadala i-Lowell Observatory eFlagstaff, e-Arizona ngo-XNUMX. U-Lowell, ngaphezu kokuba uphilanthropist kanye nesazi sezinkanyezi esiyimfundamakhwela, umuntu ocabanga kakhulu futhi ohlelekile. Ngenxa yalezo zici ikakhulukazi zendlela yokuphila, ngaphandle kokukhathala noma ukuyeka, wakwazi ukuthola iplanethi iPluto. Kodwa ngeshwa washona engazi ukuthi useyitholile.
Indlela yokuthola amaplanethi
Indlela yokusebenza esetshenziswayo ukuze ikwazi ukuchaza izindikimba zasemkhathini njengePlanethi X ebhapathiziwe noma ezinye izinto ezihamba ngaphakathi kucatshangelwa. Sakheka kanjani isimiso sonozungezilangaKulula kakhulu ukuyilandela, idinga kuphela isineke nokubekezela okukhulu. Kulula ukufunda ukuthi izindikimba zasemkhathini ezenza ukuhamba kwazo okuzungeza inkanyezi yethu, iLanga, kufanele zibe nokunyakaza okusobala uma siziqhathanisa nezinkanyezi ezingemuva kwendawo yonke.
Ngenxa yalesi sizathu, uma sikwazi ukuthatha izithombe ezihlukanisiwe, okungukuthi, zihlukaniswe isikhathi esithile, siqondise inhloso emkhakheni ofanayo Izinkanyezi kusukela phansi endaweni yonke, kuzokwazi ukubona kuzo ukuthi izinkanyezi ziyohlala ziqondile, kuyilapho izindikimba zasezulwini ezinendlela ye-orbital ezungeze iLanga, yingakho ziseduze nathi, kufanele zihambe futhi lokho kuhamba kubonakale phakathi kwezithombe nezithombe.
Yile ndlela, ngesineke esikhulu, eye yavumela izindikimba eziningi zasemkhathini ukuba zitholakale ngokulandelana kwezithombe ezithathwe phakathi nenkathi ethile yesikhathi, njengoba kwenzeka ngo-Eris.
I-Flicker Microscope
Kodwa, le ndlela icwengisiswe nakakhulu, ngoba akwanele ukuba nezithombe, kodwa ziqhathaniswa nethuluzi eliye labizwa ngokuthi i-flicker microscope. Ngalesi sisetshenziswa izithombe ezimbili zingabonwa ngokushintshana futhi izinguquko ezicashile zingatholakala. Yayisebenzisa le ndlela lapho, ngo-February 18, 1930, uClyde William Tombaugh akwazi khona ukuthola ukuba khona kweplanethi iPluto.
Ivolumu ye-Pluto
Ivolumu ye-Pluto's mass ibilokhu ingaphansi kokubuyekezwa, cishe kusukela yatholwa. Izilinganiso zokuqala zenziwa kucatshangelwa ukuguquguquka nokuphazamiseka okubonwa e-Uranus naseNeptune, kwaze kwafinyelela iphuzu lokuthi ngo-1931 i-Pluto yayinomthamo ofana nowoMhlaba.
Khona-ke, ngonyaka ka-1948, ukulinganisa okusha kwayinciphisa yaba ngosayizi obufana ne-Mars. Ngo-1975, uDale Cruikshank, uCarl Pilcher, noDavid Morrison, ososayensi baseNyuvesi yaseHawaii, bakwazi ukubala i-albedo yayo okokuqala futhi bathola ukuthi yayihambisana neqhwa le-methane, baphetha ngokuthi iPluto kwakufanele ikhanye kakhulu futhi ingakwazi. ungabi ngaphezu kwe-1% yesisindo soMhlaba.
Kwabe sekutholakala ukuthi i-albedo ka-Pluto iphakathi kuka-1,4 kuya ku-1,9 izikhathi eziphindwe ka-Earth, mhlawumbe enye yezifundo ezaqala ukubuza imibuzo. kungani i-pluto ingeyona iplanethi
Umtholi we-Pluto
UClyde W. Tombaugh ngo-1930 wayengumcwaningi osemusha, owayephathiswe isabelo sokuzama ukuthola indikimba yasezulwini eyayibhapathizwe njengePlanethi X. Ukuze enze umsebenzi ayabelwe, wayephethe abangu-13 esandleni sakhe. -intshi i-astrograph, okungathathwa ngayo izithombe zengxenye efanayo yamazulu kodwa kuhlukaniswe izinsuku ezimbalwa. Kamuva, wahlaziya izithombe ezitholwe ngesibonakhulu esicwayizayo.
Ngale ndlela, u-Tombaugh wakwazi ukwenza isilingo sokuqhathanisa phakathi kwezithombe zakhe kanye nemifanekiso uLowell ayeyitholile futhi wakwazi ukuphetha ngokuthi uLowell wayesekwazile ukuthola izithombe zePluto.
Izinsuku zokuqala zePluto zeplanethi
Izinsuku lapho i-Pluto yayibhekwa njengeplanethi zisakhunjulwa ngothando. Kwaphela amashumi amaningi eminyaka iwukulinganisa kakhulu ngoba kwakuyiplanethi encane kunazo zonke esimisweni sethu sonozungezilanga futhi ikude kakhulu nelanga. Ubukhulu bayo buyisigamu nje sobubanzi besizwe esifana ne-United States of America futhi isendaweni eqhelile kakhulu yesimiso sonozungezilanga esiye sabizwa ngokuthi i-Kuiper Belt, okwenza kudingeke ukuba kusetshenziswe isibonakude ukuyibuka.
Esinye isizathu esenza ukuba ihlonishwe ngale ndlela ukuthi kwakuwukuphela kweplanethi eyake yatholwa indawo yokuhlola e-United States.
Ukutholakala kwayo kusukela ngonyaka we-1930, lapho isazi sezinkanyezi uClyde Tombaugh, eLowell Observatory e-Arizona, esathola lelo gama ngokuhlonipha isazi sezinkanyezi esihlonishwayo saseMelika uPercival Lowell, owasisungula, nakuba lo sosayensi wayekholelwa ukuthi iMartians yayimba imigudu. itholakala endaweni ye-Pluto. Nakuba uTombaugh ephetha ngokuthi umtholi weqiniso ube nguLowell.
Ibanga elikhulu ukusuka eLangeni naseMhlabeni, kanye nobukhulu bayo obuncane, buyivimbela ekukhanyeni ngaphezu kwesilinganiso esingu-13,8 magnitude lapho isendaweni yayo engcono kakhulu ye-perihelion, yingakho ikwazi ukubonwa kuphela ngezibonakude, ukusuka ku-200 mm aperture, ngezithombe. noma ngekhamera ye-CCD. Enye ingxabano evela Kungani i-Pluto ingeyona iplanethi?
Ngisho nangalezo zikhathi ezinhle kubonakala kithi njengenkanyezi egcina isikhathi enokubonakala kwenkanyezi, okuphuzi okufiphele, ngaphandle kwezici ezikhethekile noma ezihlukile, nakuba ububanzi bayo obubonakalayo bungaphansi kwamasekhondi angu-0,1 we-arc. Kwakudingekile ukuba kulinde kuze kube ngu-2015, ngaleso sikhathi uphenyo lwesikhala se-New Horizons lwadlula i-Pluto endleleni yayo futhi ososayensi bavunyelwe ukwazisa ngokucacile ukubukeka kwayo kweqiniso okokuqala ngqa.
Igama likaPluto
Yiqiniso, ukutholakala kweplanethi entsha ngaphakathi kwesimiso sethu sonozungezilanga kwakuyizindaba ezinhle, ezahamba umhlaba wonke ngesivinini esikhulu futhi zonke izazi zezinkanyezi nezimfundamakhwela zaqala ukuthumela iziphakamiso zamagama ku-Lowell Observatory, phakathi kwazo okwakukhona iPluto.
Ngo-March 14, 1930, u-Falconer Madan, owayesebenza emtatsheni wezincwadi e-Oxford University Bodleian Library, watshela umzukulu wakhe uVenetia Burney ngalokhu okutholakele futhi wasikisela igama elithi Pluto, elaliyinganekwane yamaRoma unkulunkulu wezwe elingaphansi komhlaba.
Indaba ngemuva kwegama likaPluto nayo idumile.
Yahlongozwa intombazane eneminyaka engu-11 ubudala, uVenetia Burney, owayehlala eNgilandi, futhi yayinesithakazelo ezinganekwaneni zamaRoma futhi yaba nombono wokuqamba le planethi entsha eyisiqhwaga ngegama likankulunkulu othakazelisayo wendawo yangaphansi. Umkhulu wakhe wayisa isiphakamiso elungeni le-UK's Royal Astronomical Society, owasidlulisela kozakwabo baseMelika eLowell Observatory.
Iplanethi esanda kutholwa, okuzungeza kwayo kungaphezu kwamakhilomitha ayizigidi ezi-4.828 ukusuka elangeni, ibizokwaziwa nangokuthi iNkosi ye-Kuiper Belt.
Ukuvota nezizathu zakho
Ngazo zonke iziphakamiso ezitholiwe, ivoti bekufanele ibanjwe eLowell Observatory ukuze kukhethwe phakathi kukaMinerva, Cronos noPluto. Ekugcineni, igama elithi Pluto lithole wonke amavoti, phakathi kwezinye izizathu, ngoba izinhlamvu ezimbili zokuqala zegama (PL) zihambisana neziqalo zomsunguli walo, uMnu Percival Lowell. Ngaleso sizathu futhi, uphawu lwale planethi ngu-P kanye no-L.
I-Pluto njengeplanethi encane kanye nencazelo ye-IAU
Kodwa ngo-August 24, 2006, i-International Astronomical Union yawuchaza kabusha umqondo walokho okufanele kuqondwe njengePlanethi. Lokhu kwaholela ekucabangeni Kungani i-Pluto ingeyona iplanethi? Kusukela ngaleso sikhathi kuqhubeke, ukuze into yasezulwini ihlukaniswe njengeplanethi, kufanele ihlangabezane nalezi zidingo ezilandelayo:
Ukuba yindikimba yasezulwini enyakazayo ezungeza iLanga.
Ukuba nesisindo esanele ukuze amandla adonsela phansi aphuma kuwo anqobe amandla omzimba oqinile ukuze aze amukele ukulingana kwe-hydrostatic, nokuma kwendilinga.
Kumelwe ukuba ikwazile ukushanela eduze komjikelezo wayo wezinto.
Kuvela ukuthi i-Pluto ihlangabezana nazo zonke izidingo, ngaphandle kweyesithathu, yingakho yawa esikhundleni sayo njengeplanethi yesishiyagalolunye yesimiso sonozungezilanga, okumele icatshangelwe namuhla ngaphakathi kwesigaba Amaplanethi amancane.
Ibukeka kanjani i-Pluto?
Umsebenzi we-New Horizons space probe wathatha iminyaka eyi-9 futhi kwadingeka uhambe amakhilomitha angaphezu kwezigidi ezingu-3.000 ukuze ufike ePluto, lapho uqoqe khona idatha eyisisekelo, ulwazi kanye nezithombe eziningi, ngokusho kososayensi ababezozichaza. Kungani i-Pluto ingeyona iplanethi?
Ezithombeni ezinokulungiswa okuphezulu, ezingathathwa umkhumbi-mkhathi we-NASA we-New Horizons, kungabonakala ukuthi ubuso be-Pluto bujabulela uhla olumangalisayo lwemibala ecashile. Lezi zithombe ezintsha zePluto zimangaze abacwaningi beplanethi ngoba umkhathi womhlaba omncane, okhanyiselwe yilanga, uthwetshuliwe.
Lapho i-NASA ikwazi ukushicilela izithombe ezicace kakhulu ezazitholwe kuze kube manje ebusweni bePluto, kwakungenzeka ukuthi kubonakale ukuthi babonisa ugu olunezintaba lwalokho okwaziwa ngokuthi i-Sputnik Planum, ekwazi ukubonakala ngendlela enhle kakhulu. izintaba ezisemngceleni walo.
Craters
Kuphinde kwaba nokwenzeka ukuqaphela ukuthi i-Pluto yayinemigodi eminingi, ikakhulukazi leyo engamakhilomitha angaba ngu-250 ububanzi, futhi ebonisa izimpawu zokuthi ukuguguleka komhlabathi kanye nezinhlelo zamaphutha okungenzeka ukuthi zinemvelaphi yokwakheka komhlaba ziye zakwazi ukuchaza kabanzi ngobuso buka-Pluto, zawuphendula umhlaba omangelengele. amahlane.
Kube nokwenzeka ukuthola ukuthi isathelayithi enkulu kunazo zonke ye-Pluto yinyanga u-Charón, ethathwe isithombe ngenxa yokuhluka okuluhlaza okwesibhakabhaka, okubomvu kanye ne-infrared kwemishini yokuhlola ye-New Horizons, ngoJulayi 14, 2015, ekwazi ukuthola ukuthi yiziphi izici zayo, ezihluke kakhulu kulezo eziboniswa ebusweni bomhlaba.
indawo
Esinye sezici ze-Pluto ezingabonwa ezithombeni ezithathwe i-New Horizons space probe izinhlobonhlobo zezinhlobonhlobo ezivezwa ubuso bayo, okuhlanganisa nalokho i-NASA ekubize ngezintaba ezibunjwe ngendlela engavamile kakhulu. Lezi zintaba zivame ukubizwa ngokwethukela ngokuthi iTartarus Dorsa.
Kube nokwenzeka futhi ukubona kulezi zithombe ukuthi i-Pluto inamathafa amakhulu aneqhwa, eziye zaqanjwa ngokuthi i-Sputnik Planum. Mayelana nalokhu, abacwaningi baye bathi lokho okubonakala njengezintaba ezithombeni kungase kube amaqoqo amakhulu amanzi ayiqhwa, alenga phezu kwe-nitrogen eyiqhwa.
Lezi ezinye zeziphetho okufinyelelwe kuzo ngemva kokuhlola izithombe ezithathwe lapho uphenyo ludlula eduze kwasePluto, cishe ku-80.467 km ukusuka kuyo, ngoJulayi 14, 2015.
Iqiniso liwukuthi kuye kwenzeka ukuqagela ukuthi kunezinhlobonhlobo eziningi ebusweni balo mhlaba. Amathafa, izintaba, imigodi kanye nalokho okungase kube yizindunduma. Imininingwane emincane kakhulu ezithombeni icishe ibe ngamakhilomitha angu-0.8 ububanzi. Kuphinde kwaphethwa ngokuthi indawo yama-craters indala, nakuba indawo yamathafa ayiqhwa ayiqhwa ingeyakamuva, ngokusho kososayensi.
Amasathelayithi
Akukhona nje kuphela ukuthi kwakungathathwa isithombe sikaCharon, kodwa futhi nezithombe zeCharon, okuyisathelayithi enkulu kunazo zonke iPluto ezungezayo, zingatholakala, ngokuthola ukuthi indawo yaseCharon esenyakatho imnyama ngokwedlulele futhi inoxhaxha lwemigexo ejulile kuneGrand Canyon, eColorado.
Esinye isambulo sezithombe ezithathwe i-New Horizons space probe ukuthi uPluto unokwakheka okubukeka njengenhliziyo, futhi ubhabhadiswe okwesikhashana negama likaTombaugh Regio, lapho kubonakala khona indawo enkulu yamathafa angenawo ama-craters. kubonakala sengathi ihlehlela emuva cishe eminyakeni eyizigidi eziyi-100 ubudala. Kuphinde kwabamangaza kakhulu ososayensi ukubona ukuthi eduze nenkabazwe yasePluto kukhona ukhahlamba lwezintaba.
Ngenxa yokuthi ukuhlaziywa kwe-spectra kungenziwa kusetshenziswa i-Ralph apparatus ye-New Horizons, kube nokwenzeka ukuthola ukuthi kunenqwaba yeqhwa le-methane ku-Pluto, nakuba kunomehluko omkhulu ukusuka kwenye indawo kuya kwenye. indawo eyiqhwa ye-Pluto. .
Bese beyisishiyagalombili
Indlela yasonteka ku-Pluto ngo-2006, lapho i-IAU ichaza kabusha umqondo kanye nezici okufanele umzimba wasezulwini ube nazo ukuze zibhekwe njengeplanethi futhi isizathu esenza uPluto angahlangabezani nezidingo ukuthi Ói-orbit idlula leyo yeplanethi iNeptune.
Ngenxa yalesi sizathu, i-IAU yaphinda yayihlukanisa njengeplanethi encane, kodwa futhi yabhapathizwa njengento ye-trans-Neptunian, eyayibhekwa njengendelelo futhi yaletha ukucasuka kwabalandeli bamaplanethi amancane kanye ne-intanethi jikelele.
Qala Ingxoxo
Kubalandeli abaningi basemkhathini, Kungani i-Pluto ingeyona iplanethi? noma ukucekelwa phansi kwePluto kwabamangaza. Kodwa emibuthanweni yesayensi emhlabeni wezemfundo yezinkanyezi, kwakuyinkulumo-mpikiswano eyaqala emashumini ambalwa eminyaka ngemva kokutholakala kweplanethi encane.
Kusukela ngo-1992, izazi zezinkanyezi zaseNyuvesi yaseHawaii eMauna Kea zathola ukuthi kukhona indikimba encane yasezulwini eneqhwa eqhele kancane ukusuka emzileni weNeptune. Yaqanjwa ngokuthi I-QBI Kuiper Belt Object ka-1992, futhi ukutholakala kwayo kwaholela emcabangweni wokuthi i-Pluto ingase ibe enye yezinto eziningi ezifana neplanethi ezitholakala ku-Kuiper Belt, okungukuthi, Kungani i-Pluto ingeyona iplanethi?
Kodwa igalelo elinzima lafika ngo-2003, lapho uprofesa waseCalifornia Institute of Technology uMike Brown ekwazi ukuthola u-Eris, iplanethi encane enesisindo esithe xaxa kune-Pluto. Ngenxa yalokhu, ososayensi nezazi zezinkanyezi baqala ukuqagela ukuthi kungenzeka ukuthi kunezinye zalezi zindikimba ezincane zasemkhathini ezizungeza emkhathini. kungani i-pluto ingeyona iplanethi kucatshangelwa ngabanye.
Ngenxa yokutholakala kwakhe, uMnumzane Brown namuhla waziwa njengendoda eyabulala uPluto, ngoba esikhundleni sokuqaphela u-Eris nazo zonke izindikimba zasezulwini ezinkulu kunePluto njengeplanethi, i-IAU yafinyelela esinqumweni sokuhlukanisa iPluto njengeplanethi futhi iguqulelwe ekubeni yiplanethi. iplanethi eyi-planetoid noma encane.
I-New Horizons iphinda iqalise inkulumompikiswano endala
Kodwa ngolwazi olwatholwa ngenxa yezithombe nokuhlolwa okwenziwa i-New Horizons space probe, ingxoxo mayelana nokuhlukaniswa kabusha kwe-Pluto iyaqhubeka. Esinye seziphetho ezingafinyelelwa ku-2015, ngenxa yemiphumela yocwaningo olwenziwe e-NASA, ukuthi kwavezwa ukuthi i-Pluto inomthamo omkhulu kunalokho ososayensi ababekucabanga ekuqaleni, nakuba isekela i-thesis Kungani i-Pluto ingeyona iplanethi?
I-NASA iphinde yaphetha ngokuthi, ngokolwazi oluqoqwe yi-New Horizons probe, i-Pluto nama-satellites ayo ayinkimbinkimbi kakhulu kunalokho obekungacatshangwa, konke okwenze umhlaba wesayensi, izazi kanye nabantu abavamile bacabange ukuthi i-Pluto ingaphinde ibuye. isimo sayo njengeplanethi.
Imibono Yesayensi Yeplanethi
Ngisho nomcwaningi wezinga lika-Alan Stern uzwakalise ukungahambisani nesinqumo esamukelwa yi-IAU, wathi isizathu esenza ukuthi iPluto yehliswe esikhundleni sayo njengeplanethi, okungukuthi, isizathu. Kungani i-Pluto ingeyona iplanethi? Kwakungenxa yobude bayo bebanga ukusuka eLangeni.
Waqhubekela phambili, lapho ethi uma ukuhlaziywa kwezithombe zoMhlaba ezisendaweni ecatshangelwayo elingana noma efana nekaPluto, maqondana neLanga, kungenziwa, uMhlaba nawo uyokhishwa ngaphandle esimisweni sonozungezilanga. .
Ngo-2014, i-Harvard-Smithsonian Centre for Astrophysics nayo yayihileleke kule mpikiswano. Ngemva komhlangano wochwepheshe mayelana nencazelo yeplanethi, izethameli zavunyelwa ukuvota, futhi, njengoba kwakulindelekile, ababekhona basekela iplanethi iPluto, ngokumelene nenkolelo-mbono ye-Pluto. Kungani i-Pluto ingeyona iplanethi?
Ngakolunye uhlangothi, e-Space Institute of the University of Central Florida, kwaqalwa uphenyo olusha olusekelwe empikiswaneni yokuthi ukucekelwa phansi kwePluto ibe iplanethi encane yi-IAU kwakungeke kuthathwe njengokufanelekile.
Esitatimendeni, usosayensi wamaplanethi uPhilip Metzger uphakamise ukuthi umqondo we-IAU, ngokombono, kufanele uqondiswe emgomweni obalulekile, okuyisayensi yeplanethi, kodwa umqondo weplanethi ekhona yilowo okungekho muntu owusebenzisayo ocwaningweni lwabo. Ukusho lokhu ngoba uMetzger nethimba lakhe benza ucwaningo lweminyaka engaphezu kuka-200 futhi bathola ucwaningo olulodwa kuphela olwasebenzisa umqondo ojwayelekile wokuhlanza i-orbit owasetshenziswa yi-IAU ukwehlisela izinga le-Pluto.
Lokhu kwamenza washo nokuthi incazelo entsha ye-IAU iwubudlabha, kwathi uMetzger kamuva wengeza ngokuthi i-IAU ayizange ichaze ukuthi iqonde ukuthini ngemfuneko yayo yesithathu, okungukuthi, ukuthi kusho ukuthini ukusula umzila wakho. Usosayensi wathi uma le mfuneko ithathwa ngokoqobo, ngeke kube khona amaplanethi esimiso sonozungezilanga, ngoba ayikho iplanethi eyenza umsebenzi wokusula umjikelezo wayo.
kupholile kakhulu esikoleni
Kusukela lapho uPluto ehla esigabeni sawo seplanethi, okungukuthi, njengoba sachazwa Kungani i-Pluto ingeyona iplanethi? kwaqala ubunzima nezinkinga, hhayi emkhakheni wesayensi kuphela. Eqinisweni, akekho owayekulungele umthelela owadalwa ukuwohloka kwesithunzi.
Emkhakheni wezemfundo kwabangela isiyaluyalu, futhi asibhekiseli emibonweni yesayensi nokuhlola, kodwa kokuthile okuyisisekelo, ngoba kwasekuqaleni kwabangela igagasi lokunyatheliswa kabusha kwezincwadi zesayensi, lapho kuchazwa khona kubafundi. yale nkulungwane entsha yeminyaka ukuthi iPluto iyiplanethi encane.
Kodwa-ke, i-Pluto ikhonjiswe njengeyona planethi engeyona ethakazelisa kakhulu yokufunda ngokwakheka kwamaplanethi, uma sikhuluma ngokoqobo.
Kuye kwaboniswa, ngenxa yohambo lwe-New Horizons probe, ukuthi i-Pluto ineqhwa elikhulu, izindunduma ezenziwe ngeqhwa le-methane eliqinile, iziqongo nezintaba ezimbozwe iqhwa le-methane, kodwa ngenxa yokwakheka kwalo, iqhwa libomvu. (esikhundleni sokuba mhlophe qhwa). Okunye okushaqisayo okutholakele ukuthi i-Pluto ineqhwa elikhulu kunawo wonke elaziwayo esimisweni sonozungezilanga.
Eqinisweni, i-Pluto inamazinga okushisa anjalo okubanda kakhulu, acishe abe ngu-204,4 degrees Celsius, futhi lelo zinga lokushisa liyehla ngokuqhubekayo njengoba umjikelezo wayo uliyisa kude elangeni, okungukuthi ku-aphelion yakhe. Ngokuvamile, i-Pluto ikude kakhulu neLanga kangangokuthi ukukhanya kosuku ku-Pluto kufana nalokho okukhishwa yinyanga egcwele ebusuku Emhlabeni.
Uma silibuka ebusweni bePluto, iLanga lizovele libonakale kithi njengenkanyezi ekhanyayo. Kungenzeka ukuthi isizathu sokuthi ososayensi nabalandeli bahlale bemangele ukuhlukaniswa kabusha kukaPluto eminyakeni eyi-14 kamuva ukuphola kwayo okungenakuphikwa.
Usosayensi weplanethi u-Alan Stern uthe esitatimendeni esikhishwe yi-NASA ukuthi inkimbinkimbi entsha yohlelo lukaPluto, kusukela ekubunjweni kwayo kokuma komhlaba kuya ohlelweni lwayo lwezinyanga nomkhathi, bekulokhu kungaphezu kwamaphupho ethu amakhulu, ngokusho kwalo sosayensi, kufanele kube ngokwanele ukuphonsa emuva. ithiyori ye kungani i-pluto ingeyona iplanethi. Uphethe ngokuthi kuzo zonke izindawo asekwazile ukuya kuzona sithola ukuthi sekunezimfihlakalo ezintsha.
