Uma unentshisekelo yokwazi ukuthi yiziphi izici zamaplanethi wesimiso sonozungezilanga izingane, bese sikumema ukuthi ufunde lesi sihloko, lapho ungathola khona konke okudingayo ukuze ukwazi ukuchaza lolu lwazi ngendlela enhle.
Siyini isimiso sonozungezilanga?
Umkhathi wakhiwe yikho konke okukhona. Ngaphakathi kutholakala zonke izakhi eziphilayo nezingaphili, okuntantayo, okungabonwa, okungabonwa, okunyakazayo noma okunganyakazi. Umkhathi uqukethe zonke izinto.
Ngaphakathi kwe-Universe singathola uthuli, amaplanethi, izinkanyezi, imithala kanye nezinto eziningi. Imithala iza ngezinhlobo eziningi, owethu ubizwa ngokuthi i-Milky Way futhi unomumo wediski obonakala ngokunyakaza okuzungezayo. Ngaphakathi kwe-Milky Way singakwazi ukuthola i-Solar System, uMhlaba oyingxenye yawo.
Igama elithi Solar System livela eqinisweni lokuthi enkabeni yalo iLanga, okuyinkanyezi ekhanyayo, eshisayo nenkulu, futhi iyinkanyezi eseduze kakhulu noMhlaba. Ngenxa yobukhona beLanga, kuyenzeka ukuthi impilo iqhubeke emhlabeni, ngoba ukube asiwatholanga amandla nokushisa kwawo, uMhlaba ubuyoba iplanethi emnyama, eyihlane, eyiqhwa. Kulezo zimo, akukho okungasinda, noma okungenani hhayi izinhlobo zezinto eziphilayo esizaziyo.
Manje, ezizungeze iLanga, kunamaplanethi angu-8, angachazwa njengezizinda ezingenziwa ngegesi noma ngamatshe futhi ezihluke kakhulu komunye nomunye. Ngaphezu kwalokho, singathola futhi izingxenyana ezincane zamadwala nezinye izinto ezifana nama-asteroids ngaphakathi kweSolar System.
Kulokhu okukhulunywe ngakho ngenhla, singaphetha ngokuthi iSolar System iyiqembu lazo zonke izindikimba zasemkhathini ezihamba eduze neLanga, kokubili amaplanethi nezinkanyezi ezinomsila, ama-asteroids namanye amaplanethi amancane abizwa ngokuthi amaplanethi amancane.
Ayini amaplanethi eSolar System?
Amaplanethi akha iSolar System, ngokulandelana kokusondela kwawo eLangeni, yilawa: IMercury, iVenus, uMhlaba, iMars, iJupiter, iSaturn, i-Uranus, neNeptune. Ezokuqala ezine zibizwa ngamaplanethi angaphakathi kanti ama-4 okugcina abizwa ngokuthi angaphandle. Isizathu salokhu ukuthi ahlukaniswe ibhande lamatshe elibizwa ngokuthi ibhande le-asteroid.
Lokhu kusho ukuthi ngemva kwe-Mars, kukhona lo mdwebo owakhiwe izigidi zama-asteroid ezinhlobo eziningi, kodwa kukhona nothuli lwe-cosmic. Yonke lemizimba nayo izungeza iLanga futhi ihamba ndawonye, nakuba kwesinye isikhathi ishayisana yodwa.
IMercury, Venus, Earth and Mars yilawo okuthiwa amaplanethi anamatshe, ngoba akhiwe ngamadwala, nokho, iJupiter, Saturn, Uranus kanye neNeptune amabhola amakhulu akhiwe ngamagesi kanti amanye abonakala engenaso isandiso esiqinile. Yindawo eqinile njengokungathi yenzeka emhlabeni. Ngenxa yokuthi amaplanethi angaphandle aqhelelene kakhulu neLanga, ukushisa nokukhanya akufinyeleli kuwo njengamaplanethi angaphakathi.
Izici Zamaplanethi Ohlelo Lwelanga
Njengoba sesike sabonisa, iSolar System yakhiwe inkanyezi, esiyibiza ngokuthi iLanga futhi ephakathi nendawo; kanye namaplanethi angu-8 azungeza ngendlela eyindilinga, abizwa ngokuthi ama-orbits. Esinye isici ukuthi amaplanethi nawo anokunyakaza okuzungezayo futhi amaningana anezinto ezinamatshe ezibuye zibe nokunyakaza okuyindilinga noma okuzungezayo okuzungezile, futhi sikubiza ngamasathelayithi noma izinyanga. Isathelayithi yomhlaba yinyanga, njengoba wazi kakade.
Amaplanethi angu-8 eSolar System anomehluko omningi. Ngokuqinisekile sikholelwa ukuthi uMhlaba uyindawo emangalisayo, kodwa amanye amaplanethi anezici zawo siqu, futhi ososayensi baye bakwazi ukuthola imibuzo ethakazelisayo kakhulu ngawo. Futhi lapha sizozichaza:
K Es Es Escha! Escha Escha! Escha Escha! Escha!
Yiplanethi yokuqala ye-Solar System, ngoba yiyona eseduze neLanga.Ngenxa yokuthi i-Pluto yahlukaniswa yaba yiplanethi, iMercury yaba yiplanethi encane kunawo wonke. Indlela yayo yokuzungeza iLanga ithatha izinsuku ezingama-88 zoMhlaba.
Venus
Iplanethi yesibili ebangeni lenkanyezi ezungeza ilanga, kodwa iyiplanethi enamazinga okushisa aphakeme kakhulu njengoba amagesi atholakala emkhathini wawo awavumeli ukushisa kudlulele emkhathini. Incane kunoMhlaba, nendlela yawo I-Orbit Ukuzungeza iLanga okuphelele kuthatha cishe izinsuku ezingama-225 zomhlaba. Okuthile okungajwayelekile ngeplanethi iVenus ukuthi izungeza ibheke kolunye uhlangothi, lokhu kusho ukuthi ikwenza ibheke kolunye uhlangothi nendlela amanye amaplanethi kuSolar System enza ngayo.
Umhlaba
Yiplanethi yesithathu uma kuqhathaniswa nebanga ukusuka eLangeni, futhi yilapho sihlala khona. Ngokwaziwa nje, iyona kuphela iplanethi eSolar System eyikhaya lokuphila namanzi asesimweni solwandle, umkhathi wayo uqukethe umoya-mpilo omningi futhi unezimangaliso zemvelo ezingenakubalwa. Njengoba abacwaningi sebephethe, ukwakheka kwayo kwaqala ngemva nje kokwakheka kweLanga, cishe eminyakeni eyizigidi eziyizinkulungwane ezingu-4.5 edlule.
Mars
Abantu abaningi nezincwadi zibhekisela kuyo njengeplanethi ebomvu, ngenxa yokuthi ubuso bayo buqukethe i-iron oxide, isici esibomvu ngombala futhi siyinikeza lokho kubukeka. Njengamaplanethi amathathu ashiwo ngenhla, inesitezi esiyidwala eliqinile.
I-hypothesis enesithakazelo ososayensi abaningi namuhla ukuthi kungenzeka ukuthi i-Mars yayingaba nokuphila esikhathini esidlule, nokuthi isengaba nakho, nakuba ihluke kancane eMhlabeni. Kunezinhlelo zokuthi esikhathini esizayo amakoloni asemhlabeni afakwe ku-Mars.
I-Jupiter
I-Asteroid Belt esesikhulume ngayo ngaphambili, ihlukanisa iMars neJupiter, eyokugcina kube yileyo enomthamo omkhulu kunayo yonke eSolar System. Liyibhola elikhulu elakhiwe ngamagesi futhi linamasathelayithi amaningi noma izinyanga kunanoma iyiphi enye iplanethi ohlelweni, ngaphezu kuka-70. Esinye sezici zalo ezingavamile kakhulu ukuthi linendawo Enkulu Ebomvu, empeleni okuyisiphepho ngesimo. ye-whirlpool, ubukhulu bayo bukhulu kunobuMhlaba.
Saturn
El Iplanethi iSaturn Kungelinye ibhola elakhiwe ngamagesi, kodwa isizathu sokuthi kungani laziwa kangcono yingoba lineqembu lamasongo elimangalisayo nelingakholeki ukwakheka kwalo okwakhiwe izigidi zezingcezu zeqhwa. Yiplanethi yesithupha maqondana nokuma kwayo eLangeni, futhi iqhele ngamakhilomitha ayizigidi eziyizinkulungwane eziyi-1.4 ukusuka kuyo.
I-Uranus
Kuphinde kube yiplanethi eyakhiwe ngamagesi anezindandatho ezincane, kodwa awekho umbukwane noma abonakale njengalawo eSaturn. Iyiplanethi enomthamo weNeptune cishe ngokuphindwe kabili futhi ibukeka iluhlaza okwesibhakabhaka ngoba umkhathi wayo wenziwe ngegesi ebizwa ngokuthi i-methane. Ayizijiki yona ngokwayo, njengoba kwenza amanye amaplanethi eSolar System, kunalokho yenza ijike elibheke eceleni.
Neptune
Yiplanethi encane kunazo zonke eyakhiwe ngamagesi kuSolar System futhi iqhelelene neLanga. Ngaleso sizathu iyiplanethi yeqhwa. Inemimoya enamandla ngokwedlulele futhi isikhathi esithathayo ukuqeda ukuzungeza kwelanga iminyaka eyi-165 yoMhlaba. Ngo-2011, yaphothula uhambo lwayo lokuzungeza iLanga kusukela yatholwa ngo-1846.
