Trans-Neptunian izinto: ingqiqo, iintlobo

Lalisecaleni umnyele wethu ke ibhanti Kuiper. Yena uya phesheya, ukujikeleza kwabanye kaThixo, zangaphambili ngoko ukubona into kule isithuba kuye kwaba nzima kakhulu. Noko ke, logama nje abantu ekhoyo kwabonakala ngezibonakude ezinamandla, kuba ikwazile ukuba wenze izinto ezithile. Umzekelo, oko kwazeka ukuba izinto yothutho-Neptunian - iyunithi esisiseko ekulelona Kuiper Belt, ilifu Oort wabaphangalalisa idiskhi. Kubalulekile sihlolisise umzimba, kokutshintsha kwi "eyadini 'yale nkqubo elanga.

TNO

Trans-Neptunian izinto - kokutshintsha umzimba cosmic emhlabeni wonke orbit. Eyona idumileyo yezi zinto - iPluto, ingqalelo yiplanethi de kwango-2006. Noko ke, ukuza kuthi ga ngoku, iPluto - izinto yesibini ngobukhulu yothutho-Neptunian. Umyinge umgama ukuya izikhanyiso kula maqumrhu mkhulu ukuba iiplanethi kwisixokelelwano sethu solar - Neptune.

Okwangoku uvule engaphezu kwewaka izinto ezinjalo. Noko ke, izazinzulu bayiqonda ukukholelwa ukuba eneneni kukho abantu abaninzi ngakumbi.

Eyona inkulu izinto olun-Neptunian - Eris. Kwaba evulekile ngo-2005. Akude kakhulu emzimbeni wethu ukukhanya, ayinazo igama, uze kuvela kuluhlu kule nombolo V774104. It liyasuswa Ilanga kwi 103 units ngeenkwenkwezi.

Yonke TNO yahlulwe kumaqela amane.

nowakwakho TNO

Kwisixokelelwano sethu lelanga kukho subclass yale hlobo imizimba: into ihlukane. Wabiza ngenxa yokuba, ngokoMthetho perihelion lwemizimba anjalo zibekwe kwindawo ezikude kakhulu kuzo abanjengoNeptune, yaye ngenxa yoko alichatshazelwa womxhuzulane yayo. Le meko yenza ezi neeplaneti phantse ezizimeleyo, kungekuphela nje abanjengoNeptune, kodwa kwinkqubo solar lonke luphela.

Nngokobuchwepheshe, le izinto imizimba eyandisiweyo diski iyona. Okwangoku, idatha ziyafumaneka ezilithoba imizimba, kodwa uluhlu kungenzeka kwixesha elizayo kufutshane iya kwandiswa kakhulu.

Enye amalungu eli qela TNO - Varuna. Zisakhamisele ngoNovemba 2000.

Classical Kuiper Belt Object

Igama eli qela lwemizimba wavela inani lokuqala kubo - QB1. Kungenxa yoko le nto izinto kwelentshona ye-Neptunian, nto leyo imi ibhanti Kuiper, ngokuba cubewanos (mzuzu-bi-Ouen). Komzila ezi zinto alikho komzila abanjengoNeptune, ngoxa bona ngokwabo baye bavakalisa livakale Orbital kunye umhlaba.

Umzila inkoliso cubewanos babe imilo phantse setyhula kufutshane-moya baza. Inxalenye enkulu yale imizimba lutyekele kwi imo yekona encinane kakhulu, omnye a engile ukuthambeka enkulu kunye emzileni evuthelweyo ngakumbi.

Ezona mpawu ziphambili zale imizimba yelo qela zezi zilandelayo:

• nokujikeleza never phambana komzila kweneptune.
• Izinto azikho resonant.
• eyinqaba yabo - ngaphantsi kwe 0.2.
• bemfuno wabo Tisserand kwama-3.

ummeli Classic eli qela - Quaoar, omnye imizimba likhulu Kuiper Belt. It wavula ngo-2002.

resonant TNO

Resonant izinto yothutho-Neptunian uyolo okuwo xa livakale Orbital ne kweneptune.

Ukuhlolisisa ezi zinto kwenza kube lula ukuba bathethe malunga narrowness kwemida iinjongo resonant. Ukuze sihlale phakathi kwale mida, umzimba kufuna isixa ethile amandla, hayi ngaphezulu, ngaphantsi. Ukuqinisekisa ukuba waphuma orbit livakale, kulula kakhulu: nje unxaxho isuntswana axis semi-ezinkulu kwemida lusekiwe.

Njengoko kuvulwa izakhiwo ezintsha kwafunyaniswa ukuba ngaphezu isahlulo seshumi kubo ku livakale 2: 3 kunye kweneptune. Kukholelwa ukuba nolwalamano olunjalo ayikho ngengozi. Kungenzeka, ezi zinto yaqokelelwa yi abanjengoNeptune ngexesha ukufuduka ukuya wezijikelezi ezikude.

Phambi kokuba izinto zokuqala kwelentshona ye-Neptunian, iingcali babecinga ukuba isenzo iiplanethi ezinkulu elikhulu drive kuya kunciphisa wesiqingatha-line nokwandisa kwi semi-ngezixengxe kaZeyus Uranus nguNeptune, kunye uSaturn yavulwa.

Enye abameli eli qela yi Orc - izinto kwelentshona ye-Neptunian, ibekwe ebhantini Kuiper.

izinto disc gqwa

Lo omzimba zikummandla ezisemaphandleni wezijikelezi-langa. Ukuxinana izinto kule ndawo iphantsi kakhulu. Zonke izidumbu disc esichitha-chithwe iqanjwa ngumkhenkce.

Imvelaphi yale ndawo akuzange ngokucacileyo ngokwenene. izazinzulu abaninzi oyikholelwayo ukuba lenzeka ngexesha xa iziphumo omxhuzulane iiplanethi kuvela ukusebenza saneleyo Kuiper Belt, ukuze izibonelelo zalo asasazwa ummandla omkhulu ngaphezu namhlanje. disk saa, xa kuthelekiswa Kuiper Belt - imeko ezingazinzanga. Umzimba kuwo uhamba nje kuphela kwicala "tye", kodwa kwi "nkqo", phantse umgama elifanayo. Ukwenza umzekelo computer lubonise ukuba ezinye izinto unokuba orbit jika, inxalenye - ezingazinzanga. Oku kwenza kube lula ukucinga ukuba umzimba kukhutshwa efini Oort okanye okuninzi.

lokufumanisa entsha

NgoJulayi 2016 kwaye kwafunyaniswa izinto enye yothutho-Neptunian. imilinganiso yalo mancinci kakhulu (ubukhulu - malunga 200 km), kodwa amaxesha 160 lamawaka sitshonela kwe kweneptune. igama layo liguqulelwe ngeendlela Chinese "imvukelo." Ingaba igama into efunyenwe kuba lijikeleza kwelinye icala ukuya intshukumo kwenkqubo elanga, njengoko oku kuchazwe into yokuba nayiphi na umzimba enamandla ngokwaneleyo ukuba nempembelelo nto, ngokupheleleyo ukutshintsha orbit kuphela.

Le nesimilo kwisibonelelo intsha ukuba izazinzulu ukuba ulahlekile, kuba ngelo xesha akucaci ukuba umhlaba nendlela oku ukwenza i "bavukele" ihamba ngendledlana enjalo. Izazi bacinga kwakhona malunga khona i planethi ongaziwayo, nto leyo ibe negalelo elikhulu enjalo kwezinye imizimba.
