El uhlelo lwelanga Yakhiwa amaplanethi nama-asteroid ajikeleza inkanyezi eyodwa okuwukuvumelana kwakho konke. Inkanyezi yaziwa njengelanga. Sonke siyawazi amaplanethi nezindikimba zasezulwini ezizungeza ilanga ngqo noma ngokungaqondile, kepha kunokungabaza okuningi maqondana ukuhleleka kwamaplanethi. Uma sikhuluma ngokuhleleka kwamaplanethi asisho ibanga lapho umzimba ngamunye wasezulwini ujikeleza khona elangeni.
Ngakho-ke, sizonikezela le ndatshana ukukutshela konke odinga ukukwazi ngokuhleleka kwamaplanethi.
Ukwakhiwa kohlelo lwelanga
Siyazi ukuthi isimiso sonozungezilanga sakhiwe yibo bonke amaplanethi azungeza ilanga. Ngokuphawulekayo Yakhiwa cishe eminyakeni eyizigidi eziyizinkulungwane ezingama-4.600 edlule ngenxa yokuwa kwamandla adonsela phansi okwenzeke efwini elikhulu lamangqamuzana. Lo mcimbi uholele ekwakhiweni kwezinye izinkanyezi eziyizigidigidi, inani lazo elingakaziwa namanje. Kunososayensi abaningi abacwaninga zonke izici zesimiso sonozungezilanga ukuze bazi ukuhleleka kwamaplanethi kanye nezinye izici eziyisisekelo.
Phakathi kwezinto eziyinhloko ezinikeza ukwakheka nokuphila kohlelo lwelanga kukhona amaplanethi amakhulu namancane. Kunezinto ezithile ezifana ne-stardust, i-interstellar gas, ama-satellites nama-asteroid nawo ayingxenye yesistimu yelanga. Isethi ephelele yalezi zinto yakha lokho esikwaziyo njengokuthi IMilky Way. IMilky Way yakhiwe yizigidigidi zezinkanyezi kanti nesimiso sonozungezilanga sisesinye sezingalo ukuthi ibizwa ngokuthi i-Orion.
Phakathi kwezici eziyinhloko esinazo zesistimu yelanga esinayo ukuthi ilanga lisebenza ngama-99% wesisindo sonke sesistimu njengoba inaso ububanzi obungamakhilomitha ayi-1.500.000. Amanye amaplanethi ahlukaniswe ngezinhlobo eziningana ezaziwa ngokuthi amaplanethi angaphakathi y Amaplanethi angaphandle. Kunamaplanethi amaningi anezindandatho namanye amaplanethi amancane asesigabeni njengezindikimba ezincane zasezulwini. Kulokhu, siya kuPluto eqenjini le- Amaplanethi amancane.
Enye into ebalulekile ekwakhekeni kohlelo lwelanga yiziphuphutheki. Le yimizimba enobukhulu obukhulu futhi ezungeza iplanethi enkulu kunayo. Amaplanethi afana neJupiter aneziphuphutheki eziningi noma ngokuphambene nalokho, sineplanethi yethu lokho inenyanga kuphela njengesathelayithi. Sithole Abafowethu Abancane beziphuphutheki ezaziwa ngokuthi ama-asteroid ezitholakala ebhande le-asteroid. Leso sikhungo siphakathi Mars y I-Jupiter. Leli bhande lakhiwe ngamaqhwa, uketshezi, izinto ezinegesi, uthuli lwe-cosmic, ama-meteoroid, nezinkanyezi ezinomsila. Zimelela ezinye izakhi ezikhona ohlelweni lwelanga.
Izigaba ezintathu ze-oda lamaplanethi
Sizosungula imikhakha ehlukene okusungulwa ngayo ukuhleleka kwamaplanethi. Ukuqonda kangcono lolu hlelo, ososayensi banqume ukuhlukanisa uhlelo lwonozungezilanga ngezigaba ezintathu. Ake sihlaziye ngamunye wabo:
- Isigaba sokuqala: kulesi sigaba kukhonjiswa amaplanethi ayisishiyagalombili akha uhlelo lwelanga. Sikhomba amaplanethi asemhlabeni afana noMhlaba, iMars, Venus y K Es Es Escha! Escha Escha! Escha Escha! Escha!. La maplanethi ama-4 aziwa njengamaplanethi angaphakathi. Ngakolunye uhlangothi, sinamaplanethi aneziphuphutheki ezizungeza futhi ezikhona Neptune, I-Uranus, IJupiter kanye Saturn. Zibhekwa njengamaplanethi angaphandle.
- Isigaba sesibili: nanka amaplanethi okuthiwa amancane. Amaplanethi amancane yizindikimba zasezulwini futhi ezizungeza ilanga futhi ezinesimo esiyindilinga. Kodwa-ke, ubukhulu bayo abwenele ukusula indawo ezungeze umzila wayo. Kusuka lapha isizathu sokuqanjwa kwesibongo sivela. Amanye amaplanethi amancane enza lesi sigaba yiCeres, i-Eris, iHaumea, Pluto no-Eris. Phambilini iPluto ibithathwa njengeplanethi yesigaba sokuqala.
- Isigaba sesithathu: lapha kufakwe izidumbu ezibizwa ngokuncane zesistimu yelanga. Yizo zonke izinto ezisele esizishilo ezigabeni ezedlule. Yenziwe ngama-asteroid, zonke izinto ezisakazwa ebhandeni leKuiper, ama-meteoroid, nezinye izinkanyezi ezinomsila ezineqhwa.
Ukuhleleka kwamaplanethi
Ukuhleleka kwamaplanethi kusungulwa ngokuya ngebanga elizungeza ilanga. Sizocubungula kabanzi mayelana nomunye wabo. Sizoklelisa ngokulandelana kusuka kwesiseduze kakhulu kuya kokude kakhulu okuzungeza ilanga. Sizokhuluma nangezinye zezici eziyinhloko iplanethi ngayinye enazo.
- I-Mercury: Le planethi isondele kakhulu elangeni. Yize incane kunazo zonke ezinye ifana neplanethi yethu. Ukwakheka kwayo kungu-70% wezinto zensimbi kanye namanye ama-silicates.
- Venus: Isikhundla sesibili ngokuya ngebanga ukusuka elangeni IVenus iqanjwe ngeplanethi kaMfowethu kaMhlaba ngoba ifana kakhulu. Ukwakheka kwayo ngobuningi nangamadwala kufana nokwethu.
- Umhlaba: Inkulu kunawo wonke okuthiwa amaplanethi anamatshe futhi yakhiwa eminyakeni eyizigidi eziyizinkulungwane ezingu-4600 edlule. Amaphesenti angama-71 eplanethi akhiwe ngamanzi. Leli qiniso lehlukanise izici eziyisisekelo zeplanethi maqondana nabanye. Futhi ngukuthi lawo manzi yiwo anqume ukuba khona kwempilo.
- IMars: Ilesibili ngobukhulu bamaplanethi anamadwala futhi ingelesine ebangeni ukusuka elangeni. Kade kwaziwa njengeplanethi ebomvu isikhathi eside ngenxa yombala obomvu onayo ebusweni. Lo mbala ungenxa ye-oxide yensimbi ehlanganisa ingxenye enkulu yobuso bayo.
- I-Jupiter: Kuyingxenye yemidondoshiya yegesi eqanjwe ngoNkulunkulu uZeus wezinganekwane zamaGrikhi. Sekuvele kukhulu nge-1300 kunoMhlaba futhi kubhekwa njengeplanethi endala kakhulu kusistimu yelanga.
- ISaturn: Iyiplanethi edume kakhulu ohlelweni lwelanga ngendandatho yayo. Yatholwa okokuqala ngonyaka we-1610 kanti ingxenye enkulu yayo yakhiwa i-hydrogen kanye neqhwa lonke.
- I-Uranus: Kuyiplanethi ethathwa njengenye yezokuqala ukutholwa yisibonakude. Ukucaciswa kwayo komoya wayo. Ifinyelela emazingeni okushisa angama- -224 degrees Celsius.
- NeptuneYakhiwe ngamatshe ancibilikile, amanzi, i-methane, i-hydrogen, iqhwa ne-ammonia ewuketshezi futhi yatholwa ngonyaka we-1612.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngokuhleleka kwamaplanethi nezimpawu zesistimu elanga.
