Ungakwazi yini ukukhipha izici eziyisihlanu ezibaluleke kakhulu zenyanga kulencwadi esigabeni esisodwa?
Context:Inyanga iyona kuphela i-satellite yemvelo yomhlaba. Iyisathelayithi yesihlanu ngobukhulu ohlelweni lwelanga futhi inkulu kakhulu futhi inkulu kakhulu uma iqhathaniswa neplanethi yayo, enobubanzi obungaba yingxenye eyodwa kwezine zomhlaba (okuqhathaniswa nobubanzi be-Australia). Inyanga iyinhlangano eplanethi-mass enomzimba wamatshe ohlukile, okwenza kube yiplanethi yesathelayithi ngaphansi kwencazelo ye-geophysical yegama futhi inkulu kunawo wonke amaplanethi amancane awaziwayo weSolar System. Ayinawo umkhathi obalulekile, i-hydrosphere, noma insimu kazibuthe. Amandla adonsela phansi alo aphezu komhlaba acishe abe yingxenye yesithupha yomhlaba ngo-0.1654 g, kanti inyanga kaJupiter u-Io ukuphela kwesathelayithi eSimisweni Sokujikeleza Kwelanga esaziwa ngokuba namandla adonsela phansi aphezulu kanye nobuningi.  Inyanga izungeza uMhlaba ebangeni eliphakathi nendawo elingamakhilomitha angu-384 400 (238,900 mi), noma izikhathi ezingaba ngu-30 ububanzi bomhlaba. Ithonya layo lokudonsela phansi liwumshayeli oyinhloko wamagagasi omhlaba futhi kancane kancane lenza usuku lomhlaba lube lude. Umjikelezo wenyanga ozungeza uMhlaba unenkathi yezinkanyezi yezinsuku ezingama-27.3. Phakathi nesikhathi ngasinye sezinsuku ezingu - 29,5, inani lendawo ebonakalayo ekhanyiswa yilanga liyahlukahluka kusukela kokungekho kuze kufike ku - 100%, okuphumela ezigabeni zenyanga ezakha isisekelo sezinyanga zekhalenda lenyanga. Inyanga ikhiyiwe emhlabeni, okusho ukuthi ubude bokujikeleza okugcwele kweNyanga phezu kwe-eksisi yayo kubangela ukuthi uhlangothi lwayo olufanayo (uhlangothi oluseduze) luhlala lubhekene noMhlaba, futhi usuku lwenyanga olude ngandlela thile lufana nesikhathi se-synodic. Nokho, amaphesenti angu-59 ephelele ebusweni beNyanga angabonakala eMhlabeni ngokusebenzisa ukushintsha komjikelezo ngombono owaziwa ngokuthi i-libration.  Incazelo eyamukelwa kabanzi ngemvelaphi ithi iNyanga yakheka eminyakeni eyizigidi eziyizinkulungwane ezingu-4,51 edlule, ngemva nje kweMhlaba, emfucumfucwini yokushayisana okukhulu phakathi kweplanethi nomzimba okuthiwa usayizi kaMars obizwa ngokuthi iTheia. Khona-ke yasuka yaya emzileni obanzi ngenxa yokuhlangana kwamagagasi noMhlaba. Uhlangothi oluseduze lweNyanga luphawulwa yi- volcanic maria ("izilwandle") ezimnyama, ezigcwalisa izikhala eziphakathi kwezindawo eziphakeme ze-crustal zasendulo eziqhakazile nezimbobo ezivelele. Iningi lemigodi emikhulu yokushayisana kanye nezindawo zokushayisana kwakukhona ngasekupheleni kwenkathi ye-Imbrian, eminyakeni engaba yizigidi eziyizinkulungwane ezintathu edlule. Ubuso beNyanga abukhombisi lutho, kanti ukubonakalisa kwenhlabathi yenyanga kuqhathaniswa nokwe-asphalt. Nokho, ngenxa yobubanzi bayo obukhulu, inyanga egcwele iyinto ekhanya kakhulu esibhakabhakeni ebusuku. Ubukhulu beNyanga bubonakala bucishe bufane nobeLanga, okuyivumela ukuba imboze iLanga cishe ngokuphelele phakathi nokushona kwelanga okuphelele.  Kokubili ukuvelela kweNyanga esibhakabhakeni soMhlaba kanye nomjikelezo wayo ovamile wezigaba kuye kwanikeza izinkomba zamasiko nethonya emiphakathini yabantu kuwo wonke umlando. La mandla angatholakala olimini, ezinhlelweni zamakhalenda, kwezobuciko nasezinganekwaneni. Into yokuqala yokufakelwa eyafika eNyangeni kwakuyi - Luna 2 yaseSoviet Union eyayingenamuntu ngo - 1959; lokhu kwalandelwa ukufika ngempumelelo kwe - Luna 9 ngo - 1966. Okuwukuphela kwemishini yabantu eya enyangeni kuze kube manje kwakuyileyo yohlelo lwe-United States i-Apollo, olwaluthathe amadoda ayishumi nambili lwawafaka enyangeni phakathi kuka-1969 no-1972. Le mikhankaso neminye eyalandela engenamuntu yabuyisela amatshe enyanga asetshenziselwa ukuthuthukisa ukuqonda okuningiliziwe ngokwakheka komhlaba ngemvelaphi yeNyanga, ukwakheka kwangaphakathi, nomlando owalandela. Inyanga iwukuphela kwesidalwa sasemkhathini esiye savakashelwa abantu.
Inyanga iyisathelayithi yomhlaba eyingqayizivele, cishe engokwezine ngobukhulu bomhlaba, ineminyaka engu-4.51 ubudala, iwukuphela komzimba wasezulwini ovakashelwe abantu, futhi izungeza umhlaba ngezinsuku ezingu-27.3.
