Ngemva kweminyaka engu-11, le nqubo Amaplanethi Amancane Kusakhulunywa ngayo yize isilahlekelwe ukusebenza kwayo. Mhlawumbe ngenxa yokungaqapheli ukuthi lezi zindikimba zasemkhathini seziyingxenye yezigaba ezintsha ezakhiwe yi-International Astronomical Union (IAU). Leli qembu okukhulunywe ngalo ngenhla labamba umhlangano lapho kwethulwa ukuhlukaniswa okusha kwezinto zasemkhathini ngaphakathi kwe-Solar System, manje eseyachazwa kabusha yaba izinhlobo ezintathu.
Isigaba esithatha isikhathi esingaphezudlwana kweshumi leminyaka saba yilokho okuyikhona namuhla amaplanethi, amaplanethi amancane kanye namaplanethi imizimba emincane yeSolar System. Ngakho-ke, ukusetshenziswa kwe-Minor Planet, eyayibizwa nangokuthi i-planetoid, ilahlekelwa ukufaneleka kwayo njengoba yenza ingxenye yezinhlaka ezincane ze-Solar System ngonyaka ka-2006. Lokhu kwenzeka, njengoba lezi zindikimba zasezulwini azizona ama-satellites noma izinkanyezi ezinomsila, kodwa mancane kakhulu kunamaplanethi ajwayelekile.

Ngaphezu kwalokho, lokhu isigaba sezinkanyezi Makhulu kunama-meteoroid, ngokwesiko agqama ngosayizi ongamamitha angama-50. Kodwa-ke, ukuze kuhlanganiswe imizimba yesikhala phakathi kwezigaba ezintathu, izazi eziningi zifaka le mizimba emincane enesathelayithi, izinkanyezi ezinomsila kanye nama-meteoroids, ngaphansi kwesigaba esifanayo semizimba emincane yeSolar System. Ukuze uthole ulwazi olwengeziwe ngalezi zenzakalo, ungabheka isihloko sethu ama-asteroid.
I-IUA ichaza izindikimba ezincane zeSolar System njengazo zonke lezo imizimba yasezulwini ukuthi, ngaphandle kokuba amasathelayithi, awakafinyeleli usayizi owanele. Okusho ukuthi, abazange bafinyelele isisindo esifinyelela ukulingana kwe-hydrostatic.
Ukuhlukaniswa Kwasendulo Kwamaplanethi Amancane
Nakuba igama elithi Amaplanethi Amancane lingasasetshenziswa okwamanje, kubalulekile ukwazi isikhathi esedlule ukuthi lezi zindikimba zasemkhathini zaziyini. Zazihlukaniswa kanjani? Impendulo yalo mbuzo ukuthi Amaplanethi Amancane ngokucaciswa kwawo kwangaphambilini, ukuthi ayehlukaniswa ngemindeni namaqembu ngokuya ngezici ngayinye yazo. imizila futhi leso kwakuyisisekelo sangaphambili, ngenxa yalesi sizathu babenaleli gama elingalungile. Uma ungathanda imininingwane eyengeziwe mayelana nendlela yethu Uhlelo lomkhathi, vakashela .
Ngakolunye uhlangothi, le ndlela yokuwafaka ohlwini yenza ukuhlukana kwaba kukhulu, ngakho isiko laliwukuqamba iqembu lama-asteroid esilungwini sokuqala esasitholwe kuleli qembu, ngokuvamile elalilikhulu kunawo wonke. Imindeni yamaPlanethi Amancane ingabonwa ngaphakathi ibhande le-asteroid; kanye namaqembu, okubhekiselwe kumasoseshini ayekhululekile futhi ngenxa yalesi sizathu ayeguquguquka.
Amaplanethi Amancane Aqoshiwe
Ngokuba ukufundwa kwezinkanyezi, kubaluleke kakhulu ukwenza irekhodi lanoma yikuphi ukuphazamiseka esikhaleni. Ukutholwa noma indida ethile kufanele ibonakale ezinqolobaneni zabacwaningi besayensi bamanje nabazayo. Ngenxa yalokhu, kungenxa yokuthi namuhla izazi eziningi zingaqhubeka nezifundo zezenzakalo ezenzeka esikhathini esidlule kwezinye izingxenye zomhlaba. Universal. Futhi, isebenza njengokubambisana kwezincazelo ezifanele zezigaba, njengoba kwenzekile kuleli cala.
Ceres
Amaplanethi Amancane manje atholakala phakathi kwezindikimba ezincane zeSolar System. Kodwa ngaphambi kwalokho, kwakunohlu lwazo ezibhaliswe ngokuthi Amaplanethi Amancane. Esokuqala kwaba Ceres, eyatholwa ngonyaka omusha ka-1801 yi-Italian Giuseppe Piezzi. Nakuba iCeres empeleni yayibhekwa njengeplanethi entsha yalowo nyaka. Ngakolunye uhlangothi, i-Ceres ayihlukaniswa njengomzimba omncane, kodwa njengeplanethi encane okwamanje. Uma ufuna ukufunda okwengeziwe mayelana Amaplanethi amancane, vakashela ikhasi le-.
sedna
Enye iplanethi encane yaqanjwa ngayo sedna, ngesikhathi sika-2003 yayitholakala kunombolo 90377 ochungechungeni lwamaplanethi amancane ayetholakele futhi wafaneleka I-Laboratory ye-Jet Propulsion I-NASA njengento eqhelelene kakhulu ne-Solar System, njengoba emzileni wayo yayibonwa kakhulu ukuthi ikude neLanga.

i-orcus
Le ndikimba yasezulwini itholakala kunombolo 90482 ochungechungeni lwamaplanethi amancane ekuqokweni kwayo kwesikhashana unyaka ka-2004. Ukubaluleka kwamarekhodi kwenze uphenyo luveze ukuthi nakuba ukutholakala kwe i-orcus Kwakungonyaka ka-2004, lapho kwatholakala izithombe lapho lendikimba yasezulwini ivela khona enezinsuku zango-1951. Siphawula ngaleso sikhathi, ukuthi yayike yakha isithakazelo phakathi kwezazi zezinkanyezi yangaleso sikhathi. Ngaphezu kwalokho, ungafunda mayelana imizimba emincane yesimiso sonozungezilanga ukujula endabeni.
Ukuqokwa kwesikhashana kunikeze i-Orcus ithuba lokubhekwa njengeplanethi, yingakho ikhiqize isithakazelo esikhulu. Kodwa-ke, namuhla ayikathathwa njengeplanethi kodwa kungenzeka ukuthi esikhathini esizayo iyoba yingxenye yomunye weplanethi. Amaplanethi amancane ezikhona kuSolar System. Ngaphezu kwe-Orcus, kukhona nezinye izinto ezafakwa phakathi kwamaPlanethi Amancane, njenge: Varuna, Quaoar, Pallas, 2002aw, 2002tx, Ixion, Hygia kanye neVesta.
Imizimba emincane yeSolar System
Lezi izinto zemvelo zasemkhathini ezitholakala ku-orbit ezungeze iLanga Akuwona amaplanethi, amaplanethi amancane, noma amasathelayithi. Ngenxa yalesi sizathu, ezinye izazi zikhombisa ukuthi imizimba emincane yiwona comets, ama-asteroid kanye nama-meteoroids. Nakuba ezinye, njengoba kuchazwe ngenhla, zibonisa ukuthi imizimba emincane mikhulu, njengoba i-meteoroid, ngokwesibonelo, ikala umkhawulo wamamitha angu-50. Ukwengeza, ungafunda kabanzi ngakho kumongo wemizimba emincane.
Kodwa-ke, kusukela Umhlaba Mancane kakhulu futhi lokhu kuyisici esenza kube nzima ukuwabona futhi ahlala etholakala. Lokhu kubangela ukunemba phakathi kwengqikithi yazo. Inombolo eqondile ayaziwa, njengoba ukuzichaza kudinga ukubhekwa ngezindlela ezihlukahlukene ukuze kutholwe ukuthi yiziphi imizimba emincane eSolar System nokuthi zingaki. Ungahlola futhi isihloko sethu ku ama-asteroids athinta umhlaba ukuqonda okushiwo yile mizimba emincane.
Umzimba omncane we-Solar System, awunabo usayizi noma isisindo okwanele ukuyithatha ukuze yamukele isimo esiyindilinga esibalulekile esiyenza ibe enye yamaplanethi emzileni welanga, kulokhu ibhekisela kumaplanethi endabuko. , amaplanethi amadala kanye Amaplanethi amancane. Asikho kulezi zigaba ezinemizimba emincane.
Mayelana nalokhu, kubalulekile ukuqaphela ukuthi asikho isigaba esifanele seplanethi encane. Nakuba lokho kuchazwa, igama leplanethi encane liyagcinwa ngaphandle kokunye, njengoba ngokusemthethweni lokhu kuhlukaniswa akusasebenzi. Ngalesi sizathu, i-IAU iyaqhubeka nokwabela izinombolo kukhathalogi yamaPlanethi Amancane, ivuma isigaba phakathi kwayo ngaphansi kwegama elisha elithi imizimba yasezulwini.
Kuhlonzwe Imizimba Emisha Encane
NgoJulayi 2016, izidumbu ezincane ezingu-40 zase zihlonzwe ngaphakathi kwe-Solar System; nakuba ezinye izihloko zezindaba nazo zafundwa lapho lokhu kutholwa kwashiwo ngegama elithi Amaplanethi Amancane. Ngisho nangemva kweminyaka eyishumi ingasasetshenziswa, yigama elisamukelwayo. Ukuhlonza kwenziwa iqembu lezazi zezinkanyezi zaseYurophu ezivela I-Instituto de Astrofísica de Canarias (IAC), lokhu okutholakele kungaba nomthelela olwazini mayelana nemvelaphi yako.
Lezi izinto zasemkhathini kuzosiza ukuqonda ezinye izici mayelana i-cosmology, ephathelene nokubunjwa nokuziphendukela kwemvelo kweSolar System. Ngakolunye uhlangothi, ulwazi lungaqoqwa oluzosikhanyisela ngemithelela engenzeka eMhlabeni. Kungokokuqala ngqa ukuthi kuhlaziywe idatha yocwaningo, ehlola isampula enkulu yezinto ezincane ezizungeze iLanga.
Izazi zezinkanyezi zidinga ukwenza ukulungisa okubuyekeziwe ekuqoqweni kwedatha ukuze zithole ulwazi oluningiliziwe mayelana Nesistimu Yelanga kanye nomhlaba wonke. indawo yomhlaba. Okwamanje, izindikimba ezincane ziyindlela entsha yokubiza amaplanethi amancane, nokho amanye amarekhodi azoqhubeka nokubiza lelo gama ukuze aqhubeke nocwaningo lwangaphambilini ngale ndaba.
