Isimiso sethu sonozungezilanga sakhiwe amaplanethi namasathelayithi awo azungeza imigudu yawo ezungeza ilanga. Ngesikhathi sokudalwa kwalesi simiso sonozungezilanga naphakathi kokudalwa kwamaplanethi kwakukhona amandla ahlukahlukene abangela ukuthi amaplanethi athole umumo oyindilinga. abantu abaningi bayazibuza kungani amaplanethi ayindilinga nokuthi zakhiwe kanjani.
Ngalesi sizathu, sizonikezela lesi sihloko ukuze sikutshele ukuthi kungani amaplanethi eyindilinga, yiziphi izici zawo, nokuthi aqala kanjani ukuze abe nalesi simo.
Kungani amaplanethi eyindilinga?
Kusukela ekuqaleni kokuhlolwa kwezinkanyezi, abantu bebelokhu benesithakazelo ekutadisheni izinto esizibona esibhakabhakeni ebusuku futhi bazame ukuthola ukuthi kungani zakha. Lawa maplanethi ayingxenye yaleli qembu lezinto ezithakaselwayo. Kusukela ezikhathini zasendulo kwaziwa ukuthi la maphuzu esibhakabhakeni anesimo esicishe sibe isiyingi, futhi siyazi ukuthi sihlala kwelinye lawo. Lolu lwazi lugcinwe kuze kube yilolu suku, nakuba manje singakusho lokho sinokuqonda kangcono izinqubo zomzimba kanye nezici ezithinta ukuma kwamaplanethi.
Impendulo yalo mbuzo ilula kunalokho ucabanga, futhi ngokuyisisekelo ilele ekwakhekeni nasekuqineni kwayo. Amandla adonsela phansi asuka enkabeni aye emaphethelweni, yingakho amaplanethi evame ukumiseka njengendilinga, okuyindilinga enezinhlangothi ezintathu.
Ngesikhathi kwakhiwa amaplanethi, amaplanethi aqukethe izinto ezincibilikisiwe kanye noketshezi olushisa kakhulu. Njengoba amandla adonsela phansi ehlala edonsa isisindo sento enkabeni yayo, into eyenziwa yilolu ketshezi icindezela ibe yindilinga engaphelele enamaqhuqhuva ambalwa. Lapho iplanethi isipholile, yayiqina.
Amaplanethi ayindilinga ngoba insimu yawo yamandla adonsela phansi yenza sengathi isuka enkabeni yomzimba futhi idonsa yonke into ibheke kuwo. Amandla adonsela phansi eplanethi adonsa ngokulinganayo kuzo zonke izinhlangothi. Amandla adonsela phansi asuka phakathi nendawo aye emaphethelweni njengezipoki zesondo lebhayisikili. Lokhu kwenza umumo jikelele weplanethi ube yindilinga, okuyindingilizi enezinhlangothi ezintathu.
Ingabe bayindilinga ephelele?
Esimisweni sethu sonozungezilanga, amaplanethi abukeka emuhle kakhulu, cishe ayindilinga ephelele, ikakhulukazi iMercury, iVenus kanye noMhlaba ngokwawo. Eqinisweni, uma siyibeka esikalini sebhola lebhilidi, asikwazanga ukubona amabala. Nokho, impendulo iwukuthi amaplanethi awazona imbulunga ephelele.
Amaplanethi angashayisana nezinye izindikimba zasemkhathini, enze ama-craters noma amaqhuqhuva amise ukuma kwawo. Futhi, njengoba ehlala ezungeza, amanye amaqhubu amise okwesiyingi ayakhiwa. Uma okuthile kuzungeza, njengeplanethi, izinto ezisemaphethelweni angaphandle kufanele zihambe ngokushesha kunezinto ezingaphakathi ukuze zihambisane, futhi ngenxa yalokho ziyaqhuma eduze nenkabazwe.
Lapho iplanethi ishesha ngayo, iba nkulu iqhubu, kuye ngokuthi iplanethi ijikeleza ngokushesha kangakanani.. Ngakolunye uhlangothi, lapho iplanethi ihamba kancane, kuyancipha ukungahambi kahle okuzobonisa ukuma kwayo. Ngaphandle kokuqhubekela phambili, iSaturn neJupiter zithe ukushuba kancane phakathi nendawo ngenxa yejubane lokuphenduka kwazo.
Kukhona nezinye izinto ezingajwayelekile emkhathini, futhi zincane kakhulu. Laba abangeni engxoxweni yethu ngoba abangeni esigabeni samaplanethi. Ngo-2006, i-International Astronomical Union yahlukanisa iplanethi kulesi sigaba, okumele ihlangabezane nezici ezithile:
- kumele izungezise inkanyezi
- Kumelwe ibe nkulu ngokwanele kangangokuthi amandla ayo adonsela phansi ayenza ithathe umumo oyindilinga.
- Kufanele ibe nkulu ngokwanele ukuze amandla ayo adonsela phansi akwazi ukukhipha noma yiziphi ezinye izinto ezinobukhulu bayo ezizungeza eduze neLanga.
Akuwona wonke amaplanethi ayindilinga ngokulinganayo
Okokuqala, ake sibuyekeze amaplanethi esimiso sethu sonozungezilanga. Nazi eziyisishiyagalombili, esizibiza ngokuthi amabanga amancanyana ukuya emakulu ukusuka elangeni: iMercury, iVenus, uMhlaba, iMars, iJupiter, iSaturn, i-Uranus, neNeptune.
Kuyiqiniso elimangalisayo ukuthi kuyadingeka ukwazi ukuthi akuwona wonke amaplanethi alinganayo. Isibonelo, iMercury neVenus yizona eziyindilinga. Phakathi kwazo kungashiwo ukuthi cishe ziyizindilinga eziphelele.
Ngokuphambene, iSaturn neJupiter "ziyindilinga encane" ngoba ziminyene kancane phakathi nendawo. Okwenzekayo ukuthi njengoba ejikeleza, aqhuma eduze nenkabazwe.
Ezinxushunxushwini zoMhlaba kanye ne-Mars, umuntu angasho ukuthi mancane kuneSaturn noma i-Jupiter, futhi awaphenduki ngokushesha njengemidondoshiya yegesi (i-Jupiter, iSaturn, i-Uranus ne-Neptune). Umhlaba ujiyile ngo-0,3% empumalanga kanti iMars iwugqinsi ngo-0,6% phakathi nendawo, ngakho-ke awawona ama-sphere aphelele, kodwa ayindilinga kuneSaturn neJupiter.
Okuseduze kakhulu nezimbulunga eziphelele kukhona i-Uranus neNeptune. Eyangaphambili ijiyile ngo-2,3% phakathi kanti eyokugcina ijiyile ngo-1,7%. Ngakho-ke awaphelele njengeMercury neVenus, kodwa asondelene kakhulu.
Ukwakhiwa kwamaplanethi
Amaplanethi akha lapho izinto ezisemkhathini ziqala ukungqubuzana futhi zinamathele ndawonye. Ngemva kwesikhashana usunezinto ezanele zokukhiqiza inani elifanele lokudonsela phansi. Lawo amandla ahlanganisa izinto ezisemkhathini. Lapho iplanethi eyakhayo inkulu ngokwanele, iqala ukusula indlela yenkanyezi eyijikelezayo. Isebenzisa amandla ayo adonsela phansi ukuze ibambe izingcezu zempahla yasemkhathini.
Ngakho-ke, isimo esiyindilinga sezindikimba ezinkulu zasemkhathini kungenxa yamandla adonsela phansi. Noma iyiphi into idala inkambu yamandla adonsela phansi ezungeze yona, njengokungathi wonke umzimba womzimba ugxile phakathi nendawo futhi uheha udaba kuwo. Phakathi nenkathi ende yokubunjwa kweplanethi, izinto zazigeleza, zithintwe ukushisa kwezikhali zenuzi zangaphakathi, futhi zanqotshwa amandla anamandla adonsela phansi. Ukusabalalisa okuyindilinga kuyalingana kuzo zonke izinhlangothi futhi ukuphela kwejiyomethri egcina yonke into eMhlabeni iseduze nendawo yayo ngangokunokwenzeka.
Amandla adonsela phansi eplanethi adonsa ngokulinganayo kuzo zonke izinhlangothi. Amandla adonsela phansi asuka phakathi nendawo aye emaphethelweni njengezipoki zesondo lebhayisikili. Lokhu kwenza umumo jikelele weplanethi ube yindilinga, indilinga enezinhlangothi ezintathu.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi kungani amaplanethi ayindilinga kanye nezici zawo.
