Trans-Neptunian izinto: umqondo, izinhlobo

Emaphethelweni isimiso sethu selanga esiyingxenye le Kuiper ibhande. Uya phesheya orbit Neptune sika, sangaphambilini ukuze ukubona nganoma yini kulesi sikhala Kuye kwaba nzima kakhulu. Nokho, njengoba nje abantu etholakalayo uvele izibonakude ezinamandla, ke wakwazi ukwenza izinto ezimbalwa. Ngokwesibonelo, yabe seyaziwa ngokuthi izinto trans-Neptunian - iyunithi eyisisekelo akha lesi Kuiper Belt, ngefu i-Oort kanye disc zihlakazeke. Kuwufanele sihlolisise umzimba, ujikeleze le "ebaleni" sonozungezilanga.

TNO

Trans-Neptunian letigcogcwe ngaphambilini - umzimba cosmic uzungeza umhlaba ngaphakathi wo orbit. Isenzakalo esidume kunazo zonke lezi izinto - Pluto, kubhekwa iplanethi kuze 2006. Nokho, kuze kube manje, i-Pluto - esingesesibili ngobukhulu izinto trans-Neptunian. ibanga ezimaphakathi izinkanyiso kulezi emizimbeni kukhulu kunesono ngesikhathi Amaplanethi azungeza ilanga lethu namaplanethi alo - Neptune.

Okwamanje ukuvula ezingaphezu kwenkulungwane izinto ezinjalo. Nokho, ososayensi oyikholelwayo ukuthi eqinisweni kunabaningi.

Umhlangano omkhulu kunayo yonke izinto trans-Neptunian - Eris. Kwaba evulekile 2005. Kakhulu kude ukukhanya umzimba wethu, ayinakho igama, avele ohlwini at inombolo V774104. It esuswa Sun at 103 amayunithi yezinkanyezi.

Zonke TNO zihlukaniswe amaqembu amane.

Separated TNO

Ezisesimisweni sethu sikanozungezilanga kukhona subclass yalolu hlobo zemizimba: into bathinteka. Wabiza ngenxa yokuthi, ngokoMthetho perihelion zemizimba ezinjalo zitholakala endaweni amabanga amade uma liya kusuka Neptune, futhi kungakho alithintwa amandla adonsela phansi yayo. Lesi simo kwenza la maplanethi cishe ezizimele, hhayi kuphela Neptune, kodwa futhi kusukela ohlelweni lonke sonozungezilanga sisonke.

Ngokomthetho, lezi izinto nemizimba enwetshiwe disk iyona. Okwamanje, idatha ziyatholakala ayisishiyagalolunye yemizimba, kodwa uhlu kungenzeka esikhathini esizayo esiseduze uzobe kakhulu anda.

Omunye amalungu aleli qembu TNO - Varuna. Kuvulwe ngo-November 2000.

Classical Kuiper Belt Into

Igama leli qembu emizimbeni zazivela izinombolo wokuqala wabo - QB1. Yingakho izinto trans-Neptunian, okuyinto Itholakala Kuiper ibhande, ngokuthi cubewanos (lokubonisa-bi-Ouen). Emzileni letintfo alikho emandleni abo emzileni Neptune, kuyilapho bona baye bazwakalisa i resonance esemkhathini ne iplanethi.

Umzila wenyanga iningi cubewanos babe ukuma ucishe ube isiyingi eduze indiza Ecliptic. Ingxenye enkulu lezi zindikimba uthambekele engela encane kakhulu, ezinye has a enyakazayo engeli enkulu omise side kakhudlwana.

Izici eziyinhloko izidumbu fanele kuze lo xuku kukhona okulandelayo:

• zazo zingaphazami neze aphambana emzileni Neptune.
• Izinto akuzona resonant.
• eyinqaba yabo - engaphansi kuka 0.2.
• umbandela yabo Tisserand kuka 3.

omele Classic yaleli qembu - Quaoar, omunye emizimbeni ngobukhulu kule Kuiper Belt. Yavula ngo-2002.

resonant TNO

Resonant izinto trans-Neptunian are labo ukulokho resonance esemkhathini ne-Neptune.

Ukuhlolisisa letintfo kwenza kube nokwenzeka ukuba ukhulume ngayo narrowness of imingcele izinto resonant. Ukuze sihlale ngaphakathi le mikhawulo, umzimba udinga ethile namandla, engasekho futhi akukho kancane. Qinisekisa ukuthi baphuma orbit resonance, silula: nje ukuphambuka amancane ukutsheka semi ezinkulu emingceleni kusungulwa.

Njengoba kuvulwa izakhiwo ezintsha kwatholakala ukuthi ngaphezu okweshumi wabo e resonance 2: 3 ne-Neptune. Kukholakala ukuthi ubuhlobo obunjalo akuyona ngephutha. Cishe, lezi izinto zathathwa ngo-Neptune ngesikhathi ukuthuthela omise ezikude.

Ngaphambi izinto zokuqala trans-Neptunian, OCHWEPHESHE bezemishado babecabanga ukuthi isenzo amaplanethi amakhulukazi kwi drive omkhulu kuzonciphisa nengxenye yomugqa futhi anda semi-eksisi Jupiter Uranus, Neptune, kwaphinde kwavulwa Saturn.

Omunye bale iqembu kuyinto Orc - izinto trans-Neptunian, ise Kuiper ibhande.

Gqwa disc izinto

Lona emizimba ezisendaweni esemajukujukwini kakhulu yesimiso sethu sonozungezilanga. I kwabantu of izinto kule ndawo sincane kakhulu. Zonke iyona emizimbeni disc yakhiwa ice.

Umsuka kule ndawo ayizange ecacile ngempela. Ososayensi abaningi kukhona oyikholelwayo lenzeka ngesikhathi lapho imiphumela okudonsa amaplanethi avele umphumela esinganele Kuiper Belt, ukuze izikhungo zayo besakazeke endaweni inkulu kakhulu kunangendlela namuhla. idiski gqwa, kuqhathaniswa Kuiper Ziyisivikelo - ngoLwesithathu edlulayo. Umzimba therein ukuhamba hhayi kuphela "ovundlile" isiqondiso, kodwa futhi "mpo", cishe ngebanga elifanayo. Ikhompyutha ukumodeliswa selukhombisile ukuthi ezinye izinto zingase abe uhambahamba orbit, ingxenye - engazinzile. Lokhu kwenza kube nokwenzeka ukuba singaphethi ngokuthi umzimba kungenziwa adedelwa ngefu i-Oort noma okuningi.

ukutholakala entsha

Ngo-July 2016 kwatholakala eyodwa ngaphezulu izinto trans-Neptunian. Ubukhulu balo mancane kakhulu (ubukhulu - mayelana 200 km), kuba ayizinkulungwane 160 izikhathi fainter kuka Neptune. Igama layo lihunyushwe kwelesiHeberu Chinese izindlela "ukuhlubuka." Ingabe igama into etholakele ukuthi uzungeza okuhlukile ukuhamba komthala wethu, njengoba lokhu zingachazwa kuphela yokuthi yimuphi umzimba ngokwanele enamandla ukuthonya ke, isinyathelo esinqala sokushintsha orbit.

Lokhu uhlamvu sikhungo esisha buye baphoqa ososayensi ukuba ulahleke, ngoba okwamanje akucaci ukuthi iplanethi kanye nendlela elingatholakala ngayo ukwenza "ukudlubulunda 'ihamba orbit ezinjalo. Izazi zezinkanyezi ucabange futhi mayelana nokuba khona kwamakamu i iplanethi engaziwa, okuyinto kungaba nomthelela onamandla kangaka ku kweminye imizimba.
