Isimiso sonozungezilanga kanye nendawo yonke iphethe inqwaba yezimfihlo isintu esingasondeli nakude ekuzitholeni. Nokho, ngokuhamba kwesikhathi, Imizamo yokwembula ezinye eziyisisekelo isithele izithelo. Isibonelo salokhu yizinto ze-Trans-Neptunian, izinhlangano ezingavamile ze-cosmic, kuze kube muva nje, zinencazelo ehlukile. Wonke umbono ocatshangwayo owawunawo mayelana nenani lamaplanethi akha isimiso sonozungezilanga usushintshile namuhla.
Ekuqaleni, kwasungulwa ukuthi I-Pluto yayingowokugcina kumaplanethi akha le ngxenye yomthala. Nokho, umbono ovezwe ezikhathini zamuva uwuguqule ngokuphelele lo mbono.

Izinto ze-Trans-Neptunian: Yilokhu okwaziwayo ngazo

Njengoba kushiwo kahle, i-angle yokubuka yesimiso sonozungezilanga ishintshiwe ochwepheshe, bahlanganisa igama elifaneleka kakhulu. Ekuqaleni, u-Pluto kwakucatshangwa ukuthi uyisidalwa sokugcina sasezulwini esimisweni sonozungezilanga, ngale komjikelezo weNeptune. Kuze kube yileso sikhathi, kwakungaziwa ubukhona obuqondile bezinye izinhlangano ze-planetoid ezifana ne-Pluto, ngakho, isikhathi esithile, leso sisekelo sagcinwa.
Ngenxa yophenyo olunembe kakhudlwana neziphetho ezifanele, kwatholakala ukuthi i-Pluto yayingeyedwa, kodwa yayiyingxenye yenethiwekhi enkulu. Ngale kwemikhawulo yayo, inani lezinto ezifanele ze-trans-Neptunian zatholwa ngendlela efanayo.
Ngakho zingachazwa kanjani lezi “zinto”? Nokho, kulula. Ngayinye yalezi zinto ze-trans-Neptunian inomjikelezo njengamanye amabhizinisi ku-cosmos. Ngakho-ke, afakiwe kulelo gama lapho kuthiwa i-orbit ingaphezu kweNeptune, ngokuphelele noma kancane.
Kulungile, uPluto akayedwa; nokho, akusho ukuthi zonke lezi zinto ziletha ukuvelela okuphelele. Ngokuphambene nalokho, iningi libonisa usayizi omncane uma kuqhathaniswa ne-Pluto. Nakuba, ngendlela efanayo kukhona nobufakazi babanye ngokubaluleka nokubaluleka kwesayensi.
Akwaziwa kahle ukuthi bafike kanjani lapho, kodwa imibono eminingana isungula lokho kanye Babeyingxenye yokudalwa kwamaplanethi amakhulu. Ahlukaniswa noma ahlukaniswe ngokuvumelana nethonya lohlobo lwe-orbital resonance abalisebenzisayo ku-Neptune. Labo abanesici esinjalo yilabo ababizwa ngama-Plutinos; kuyilapho labo abangaziwa ngokuthi amaCubewanos.
Ingabe ufuna ukwazi? Lezi yizinhlangano ezaziwayo ze-trans-Neptunian!
Ngokungangabazeki, inani lezinto ezinalezi zimpawu cishe azinakubalwa futhi ucwaningo lubonisa ukuthi kungase kube nokunye. Kubo bonke ababunjwa nosayizi abangaba khona, abanemizungezo eyi-elliptical noma yendabuko, ama-trans-Neptunian adlulela ngale kwe-Neptune. Naphezu kokuqhelelana kwabo, ekugcineni ukuziphatha kwabo kutholakele futhi usuku ngalunye oludlulayo, izimfihlakalo ezintsha ziyembulwa.
Ukuze kutholwe kahle isikhundla sabo nobudlelwano maqondana neNeptune, bafakwe emaqenjini noma ezigabeni ezahlukene. Ukuhlukaniswa ngakunye kubhekisela ezindaweni ezisuswe ngokuphelele ekushiseni kweLanga, lapho amazinga okushisa ebanda ngendlela engenabuntu, engenalo ithuba lokuphila.
Okokuqala, kukhona i-Kuiper Belt, kabani umthethosisekelo uhlanganisa amabhizinisi anomculo we-orbital omningi kancane phezu kweNeptune. Ngokulandelayo, ebangeni elilinganayo, i-Scattered Disk kanye ne-Oort Cloud.
Ngayinye igcwele ama-trans-Neptunians amangalisayo, afundwa isayensi yamanje futhi enza ingxenye yebhulogi yezinto ezisanda kutholwa. Impela, ukuphenya kabanzi ngakho, isinyathelo ngesinyathelo abanye bazovela endaweni yesehlakalo, ukuletha namaqiniso amasha mayelana neSolar System njengoba sisazi.
I-Kuiper Belt: Inkambu egcwele izinto ezinethonya ku-Neptune.
Ungasho ukuthi le ngxenye yesimiso sonozungezilanga ifana nedlelo eligcwele izihlahla, izihlahla kuphela eziyizinto ze-trans-Neptunian. Inani lalezi zinto likhulu, ngakho-ke, futhi njengoba sekushiwo, zihlukaniswe zibe iqiniso elibalulekile: ithonya labo kuNeptune.
kusho ithonya iqondiswa yisakhiwo esaziwa ngokuthi i-orbital resonance, into ekwaziyo ukuguqula imigudu yezindikimba zasemkhathini. Ngakho-ke, lawo anenye i-resonance ne-Neptune ahlukaniswa ngokwesilinganiso lapho enza ngaso lowo mphumela.
Labo 3:2 resonance kukhona ezibaluleke kakhulu, ngokuthi Plutinos, ngenxa yezici zayo ezifana ne-Pluto. Njengoba kulindelekile, kuleli qembu kuneplanethi encane kanye nabanye abadumile abanjengoCharon, Haumea kanye neMakemake.
Ngakolunye uhlangothi, futhi uphethe iCubewanos edumile, ithonya layo ku-Neptune liyize noma lingasho lutho. Phakathi kwazo, ezinye ezifana neQuaoar, Varuna noma Logos, zivame ukubonakala ukuze zifundwe njalo.
I-Scattered Disk kanye ne-Oort Cloud: Ngale kwe-Kuiper Belt

Mayelana neDiski ehlakazekile, kuncane kakhulu okutholakele ngayo. Ibanga layo kanye nokubona kunzima kakhulu, kodwa noma kunjalo, imizimba engaphezudlwana kuka-80 ebizwa ngokuthi "izinto ezihlakazekile" ezitholakele. Okubaluleke kakhulu i-Eris, enobukhulu obulingana ne-Pluto ngokwayo.
Iningi lomphakathi wesayensi lisungula ukuthi, ekuqaleni, Babeyingxenye ye-Kuiper Belt., kodwa ekugcineni zaphushwa i-orbital resonance.
Kusho ukuthini lokhu? Ngokuyisisekelo, izinto ezihlakazekile zinemizila engazinzile futhi ngokwazo, kuhambisana nomthelela weNeptune, ngokuhamba kwesikhathi. bayohlukaniswa ngisho nangale kwe-Oort Cloud.
Ngakolunye uhlangothi lohlamvu lwemali, i-Oort Cloud edumile nayo idlala indima ebalulekile ekutholweni kwesayensi. Yakhiwe nge-Hills Cloud noma i-discoidal rim yangaphandle kanye nerimu elingaphakathi elinesakhiwo esiyindilinga.
Ngezinhloso ezingokoqobo, itholakala eduze nezindawo ezingaphandle zesimiso sonozungezilanga ngenxa ye-orbital resonance eyenziwa amaplanethi amakhulu. Kuyingxenye ebalulekile yemibono ehlukahlukene, esetshenziswa kakhulu njengamanje yilena ebeka ukuthi kungaba umsuka we Inkanyezi enomsila yohlobo lwe-Halley. Njengokungathi lokho akwanele, iyindlunkulu eyinhloko yento ye-trans-Neptunian eyaziwa ngokuthi i-Sedna, enye yezinhlangano zesayensi eziyinhloko eziphenywa kakhulu njengoba sekwaziwa ngayo.
