Ngabe yini i iplanethi? izingxabano uqhubeke

Uma ngabe wazi ukuthi iplanethi ke wena wazi ngaphezu ososayensi, izazi zezinkanyezi. Ngenxa kabakholwa ekuchazweni kwethemu. Ngokwesibonelo, abanye abantu becabanga ukuthi Pluto iplanethi, abanye - akukho.

Ekuqaleni babiza Mars, Venus, Jupiter, Saturn, i-Mercury. By the way, amagama amaplanethi beza kithi kusukela zamaGreki namaRoma. Izwe lalingaphansi elikhethekile lasendulo, ihlukile kwezinye izinto ezingcwele. Inyanga ilanga, futhi, njengoba amalungu "Izidumbu ezulazulayo" bemvelo ukuhluka. Ingabe wake wazibuza ukuthi kungani sibhekana nale olulodwa ucime izinsuku eziyisikhombisa? Lokhu kubonakala ngolimi Russian. Kodwa kule isiFulentshi, isiNtaliyane, isibonelo, ukuhlanganisa ocacile phakathi lokhu "Ezinhle Seven" kanye emalanga eliviki: UMsombuluko - Moon ngoLwesibili - Mars ngoLwesithathu - Mercury, ngoLwesine - Jupiter, ngoLwesihlanu - Venus ngoMgqibelo - Saturn, ngeSonto - elangeni .

Uranus kwatholakala ekhulwini le-18. Khona-ke, sibonga cwaninga Verrier futhi Adams, Neptune (ekhulwini le-19). Ngo-1930, emhlabeni wafunda bokuba khona Pluto. Lokhu okwatholakala Klayd Tombo. Pluto namanje ukubizwa ngokuthi iplanethi lesishiyagalolunye. Ingabe kuyiqiniso lokhu? Ukuze uphendule lo mbuzo, kumelwe siqonde ukuthi kule planethi?

Kwamiswa Lolu umqondo esinakho ngokomlando. Esibhakabhakeni sibona amaplanethi ayisihlanu angase ngeso lenyama. Futhi zonke kwakuyoba nzima kakhulu, uma asteroyidi bebelokhu okuhle kodwa. Izazi zezinkanyezi bavumile ukubiza into iplanethi ukuthi azungeza inkanyezi, ngaphezu kwalokho, kufanele ibe nkulu ngokwanele ukuthi ube sphere ngenxa amandla adonsela phansi. lezinkanyezi ezinomsila Abaningi futhi asteroyidi kuyinto amafomu engajwayelekile.

definition eqondile "Yilokhu iplanethi" wayengekho. Nokho angaphezu Pluto wanamathela leli gama. Eqinisweni, lena into eyisimanga impela, futhi ihluke kakhulu kwethi eminye imihlaba ezinkulu. orbit kuyinto side kancane ngaphezulu. Kwabe sekuvela ukuthi, Pluto lincane kakhulu. Okuningi esingaphansi izazi zezinkanyezi kwakucatshangwa. Zonke amaplanethi yesimiso sonozungezilanga zitholakala "kuyanda" 4 eliwumhlaba ekuqaleni, ngaleso sikhathi amaplanethi amakhulukazi. Pluto lapha ngokucacile ayilingani.

Khona-ke wathola inyanga Pluto sika - Charon, okuyinto cishe usayizi ofanayo. Libuye kancane atypical: zonke iziphuphutheki planethi lincane kakhulu.

Kuiper (isazi sezinkanyezi saseMelika u) wasikisela ukuthi ngale Neptune kuyinto ibhande elisemkhathini. Yaba enye buhlungu "isimo" ka-Pluto. izikhathi ezinjalo ngempela lapho! Okwamanje, ubizwa ngokuthi Kuiper Belt ezaziwayo. Umzimba kukhona athé ukwehluka asteroyidi. Kodwa kakhulu afana Pluto, kuphela amancane ngosayizi. Manje kwaba sobala ukuthi i-Pluto - enye yezindawo ezinkulu kakhulu Kuiper ibhande izinto. Kodwa ngenkathi igama wangaphambili azigcina. Ososayensi, esikhathini esiningi, abantu ngoludala, ngakho baye banquma ukushiya izinto njengoba zinjalo.

Kodwa nokho, yilokho iplanethi? Esikhathini esizayo esiseduze le nkinga kuzoba kubaluleke kakhulu. Njengoba kuyaziwa ukuthi isivuliwe kakade amaplanethi nezinye izinkanyezi.

The main agumenti - mass. izinto ezincane - asteroyidi okukhulu ngaphezulu - inkanyezi. Nge izinkanyezi zonke ecacile. Bafanele babe izinga lokushisa eliphakeme, ukubeka izinqubo iArmagedoni. A iplanethi emzileni wawo kufanele babe munye, uma izinto eziningi ( "Leli bhande"), kuba asteroyidi.
