Isathelayithi yethu, iNyanga, ibekwe kumgama ophakathi weekhilomitha ezingama-384.400 ukusuka eMhlabeni. Unyaka ngamnye ushenxisa iisentimitha ezi-3,4. Oku kuthetha ukuba ngokuhamba kwezigidi zeminyaka inyanga ingayeka ukuba sisathelayithi yethu. Kuthekani ukuba imeko ibichasene? Oko kukuthi, ukuba inyanga ibisondela kufutshane kwiplanethi yethu minyaka le. Le nyani yaziwa njenge Umda weRoche. Uthini umda weRoche?
Kule nqaku sichaza yonke into malunga nayo.
Ukuba inyanga isondele kwiplanethi yethu
Okokuqala, kufanele kukhankanywe ukuba le yintsomi kwaphela. Inyanga ayinandlela yakusondela kwiplanethi yethu, ke konke oku kukuqikelela. Ngapha koko, inyani, inyanga iya kuqhubeka nokuhambela phambili ngakumbi nangakumbi eMhlabeni minyaka le. Masibuyele emva xa iplanethi yethu yayisandula ukwenziwa kwaye i-orbit eyayinayo isathelayithi yethu yayikufutshane kunale ikhoyo ngoku. Ngeli xesha umgama phakathi kweplanethi kunye nesathelayithi wawumncinci. Ukongeza, uMhlaba ujikeleze ngokwawo ngendlela ekhawulezayo. Iintsuku zazineeyure ezintandathu kuphela ubude, kwaye inyanga yathatha kuphela iintsuku ezili-17 ukugqibezela ukujikeleza kwayo.
Umxhuzulane owenziwa yiplanethi yethu enyangeni yeyona nto yayijongene nokucothisa ukujikeleza kwayo. Kwangelo xesha, umxhuzulane obangelwa yinyanga kwiplanethi yethu yeyona nto icothisa ukujikeleza. Ngesi sizathu, namhlanje iintsuku eMhlabeni ziiyure ezingama-24 ubude. Ngokuhlala kumandla angular enkqubo, yinyanga ebishenxela kude kuthi ukuba ibuyekeze.
Ulondolozo lwe-angular umfutho yinto ebalulekileyo ekufuneka igcinwe kuwo omabini amacala. Ukuba inyanga ithatha ngaphezulu kosuku ukujikeleza, isiphumo siya kufana nesibona apha. Oko kukuthi, ujikelezo lweplanethi lucothisa kwaye isathelayithi iyashenxela kude ukuze ibuyekeze. Nangona kunjalo, ukuba inyanga ijikeleza ngokukhawuleza kuyakuvelisa iziphumo ezichaseneyo: Ujikelezo lweplanethi luza kukhawulezisa, iintsuku ezihlala ixesha elincinci kunye nesathelayithi iya kusondela ngakumbi ukubuyekeza.
Iziphumo zomxhuzulane kumda weRoche
Ukukuqonda oku, kufuneka sazi ukuba amandla omxhuzulane aya esiba nzima xa sisondela ngokwaneleyo. Kukho indawo apho konke ukuhlangana komxhuzulane kungqinelana. Lo mda ubizwa ngokuba ngumda weRoche. Imalunga nefuthe lento enayo xa ixhaswa ngumxhuzulane wayo. Kule meko, sithetha ngenyanga. Ukuba inyanga isondele kwenye into kangangokuba ubunzima bomxhuzulane bunokuphela buwonakalisa buze buyonakalise. Lo mda weRoche ukwasebenza nakwiinkwenkwezi, iiasteroids, iiplanethi kunye neesathelayithi.
Umgama ochanekileyo uxhomekeke kubunzima, ubungakanani kunye nokuxinana kwezinto zombini. Umzekelo, umda weRoche phakathi koMhlaba nenyanga ziikhilomitha ezingama-9.500. Oku kuthathelwa ingqalelo ngokunyanga inyanga eqhelekileyo evela eqinileyo. Lo mda uthetha ukuba, Ukuba isathelayithi yethu ibinokuba ngama-9500 eekhilomitha okanye ngaphantsi, ubunzima beplanethi yethu buya kuthatha owayo. Ngenxa yoko, inyanga yayiza kuguqulwa ibe sisangqa samaqhekeza emathiriyeli, yaphulwe ngokupheleleyo. Izinto zokusebenza ziya kuqhubeka zijikeleza uMhlaba zide ziphele ukuwa ngenxa yesiphumo somxhuzulane phezu komhlaba. Ezi ziqwenga zezinto zinokubizwa ngokuba zii-meteorites.
Ukuba i-comet ibikumgama ongaphantsi kwe-18000 yeekhilomitha ukusuka emhlabeni ibiya kuphela kwaye iphazanyiswe sisiphumo somxhuzulane. Ilanga liyakwazi ukwenza umphumo ofanayo kodwa ngomgama omkhulu kakhulu. Oku kubangelwe bubungakanani belanga xa kuthelekiswa neplanethi yethu. Ubukhulu besayizi wento, kokukhona amandla amakhulu omxhuzulane. Le ayisiyongcamango nje, kodwa ukutshatyalaliswa kwesathelayithi ziiplanethi zabo yinto eza kwenzeka kwi inkqubo yelanga. Owona mzekelo waziwa kakhulu yile yePhobos, isathelayithi ejikelezayo ejikeleze isijikelezi langa uMars kwaye oko ikwenza ngesantya esikhawulezayo kunokuba iplanethi isenza ngokwayo.
Ngaphakathi komda weRoche, ngumxhuzulane wento encinci engenakubamba isakhiwo sayo kunye. Ke ngoko, njengoko into isondela kumda wekomkhulu laseRoche lichaphazeleka ngamandla womxhuzulane womhlaba. Xa uwela lo mda iminyaka eliqela ezizigidi ukusukela ngoku isathelayithi iya kuba sisangqa samaqhekeza ajikeleza iMars. Nje ukuba onke amaqhekeza ajikeleze okwethutyana, aya kuqala ukubonakala kumphezulu womhlaba.
Omnye umzekelo wento enokusondela kumda weRoche, nangona ingaziwa kakuhle, yiTriton, esona satellite sikhulu emhlabeni. Neptune. Ngaphezulu okanye ngaphantsi kuqikelelwa ukuba malunga nezigidi ezi-3600 zeminyaka izinto ezimbini zinokwenzeka njengoko le satellite isondela kumda weRoche: inokuwela kwimeko-bume yomhlaba apho iya konakala khona okanye iyakuba siseti yamaqhekeza emathiriyeli afana nentsimbi leyo iplanethi inayo Saturn.
Umda kaRoche kunye nabantu
Singabuzwa lo mbuzo: kutheni le nto iplanethi yethu ingasonakalisi ngomxhuzulane wayo xa ucinga ukuba sikumda weRoche? Nangona kunokwenzeka ukuba ibe sengqiqweni, inempendulo elula. Umxhuzulane ugcina imizimba yazo zonke izinto eziphilayo kunye kumphezulu weplanethi.
Esi siphumo asinantsingiselo xa kuthelekiswa neebhendi zamachiza ezibambe umzimba uphela. Umzekelo, la mandla agcinwa yimixokelelwane yemichiza emzimbeni wethu omelele kakhulu kunamandla omxhuzulane. Ngapha koko, amandla emxhuzulane yenye yezona zinto zibuthathaka kakhulu kuyo yonke imikhosi kwindalo iphela. Inqaku apho umxhuzulane usebenza ngamandla kunokuba yimfuneko Umngxunya omnyama ngokungathi ukwenza umda weRoche ukwazi ukoyisa imikhosi ebambe imizimba yethu ngokudibeneyo.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nomda weRoche.
