Ngokuqinisekileyo sonke siyayazi eyahlukileyo izigaba zenyanga edlula kuyo inyanga yonke (umjikelo weentsuku ezingama-28). Kwaye kuxhomekeke kumhla wenyanga esikuyo sinokubona isathelayithi yethu ngendlela eyahlukileyo. Ayisiyiyo indawo enye kuphela kuyo yonke imihla, kodwa kuxhomekeke nakwindawo esikuyo. Amanqanaba enyanga ayinanto ngaphandle kokutshintsha kwindlela ekhanyisa ngayo xa ijongwa eMhlabeni. Utshintsho lujikeleze kwaye luxhomekeke kwimeko efanayo ngokubhekisele kuMhlaba nakwiLanga.
Ngaba uyafuna ukwazi ngokweenkcukacha zithini izigaba zenyanga kwaye kutheni zisenzeka? Kule post unokufumana lonke ulwazi oluyimfuneko 
Ukuhamba kwenyanga
Isathelayithi yethu yendalo ijikeleza kwi-axis yayo, kodwa ikwajikeleza ngokuqhubekayo kwiplanethi. Ngaphantsi okanye ngaphezulu Kuthatha malunga neentsuku ezingama-27,3 ukujikeleza uMhlaba. Ke ngoko, kuxhomekeke kwindawo esiyifumana kuyo ngokubhekisele kwiplanethi yethu kunye neziganeko zokuziqhelanisa ngokubhekisele kwilanga, kukho utshintsho olujikelezayo kwindlela esiyibona ngayo. Ngaphandle kwenyani ekucingelwa ukuba inyanga inokukhanya kwayo, kuba inokubonwa njengenye yezona zinto ziqaqambileyo esibhakabhakeni sasebusuku, oku kukhanya akukho nto ngaphandle kokukhanya kwelanga.
Njengoko ukujikeleza kwenyanga kuqhubela phambili, ukumila kwayo kuyatshintsha ukusuka kumjongi woMhlaba. Ngamanye amaxesha unokubona kuphela icandelo elincinci lalo, ngamanye amaxesha linokubonwa ngokupheleleyo, kwaye ngamanye amaxesha alikho nje. Ukuyenza icace, inyanga ayitshintshi imilo, kodwa ziziphumo ezibonakalayo kuphela ezibangelwa kukushukuma kokunye kunye nelanga elibonakala kumphezulu walo. Ezi zii-engile apho ababukeli eMhlabeni bajonga indawo ekhanyayo yendawo yakho.
E-Spain sinokuba nenyanga epheleleyo, ngelixa e-United States inokuba i-waxing okanye iyancipha. Konke kuxhomekeke kwindawo eMhlabeni esiyijonga kuyo inyanga. Kwakhona, kubalulekile ukwazi ukuba njani unokuwubona uMhlaba ukusuka enyangeni.
Umjikelo wenyanga
Isathelayithi inonxibelelwano lwamaza kunye nomhlaba wethu. Oku kuthetha ukuba isantya sokujikeleza kwayo silungelelaniswe nexesha lokuhamba. Ngenxa yoku, nangona inyanga nayo ijikeleza ngokuqhubekayo kwi-axis yayo njengoko ijikeleza umhlaba, sihlala sibubona ubuso obufanayo benyanga. Le nkqubo yaziwa njengokujikeleza okungqameneyo. Kwaye, nokuba sijonga phi inyanga, siyakuhlala sibona ubuso obufanayo.
Umjikelo wenyanga uhlala malunga neentsuku ezingama-29,5 phakathi kwazo zonke izigaba zinokujongwa. Ekupheleni kwesigaba sokugqibela, umjikelo uqalwa kwakhona. Oku kuhlala kusenzeka kwaye akupheli. Amanqanaba aziwa kakhulu enyangeni zi-4: inyanga epheleleyo, inyanga entsha, ikota yokugqibela kunye nekota yokuqala. Nangona zaziwa kakhulu, zikhona ezinye izihambisi ezibalulekile kwaye ezinomdla ukuzazi.
Ipesenti yokukhanya kwenyanga esibhakabhakeni iyahluka njengoko iimilo zivela. Iqala nge-0% yokukhanya xa inyanga isentsha. Oko kukuthi, akukho nto siyibonayo esibhakabhakeni. Ingathi inyanga iphelile esibhakabhakeni sethu. Njengoko izigaba ezahlukeneyo ziqhubela phambili, ipesenti yokukhanya iyanda ide ifike kwi-100% kwinyanga epheleleyo. Lo mjikelo wenyanga awukho nje umdla, kodwa unxulumene neziganeko ezifana ne iinyikima ezinkulu.
Isigaba ngasinye senyanga sithatha malunga neentsuku eziyi-7,4. Oku kuthetha ukuba iveki nganye enyangeni siya kuba nenyanga ekwimo enye. Kuba umjikelo wenyanga ububude, eli xesha kunye neemilo ziyahluka. Ngokubanzi, zonke izigaba zenyanga ezinokukhanya okungaphezulu kweentsuku ezingama-14,77 kwaye ziyafana kwezo zigaba zimnyama.
Izigaba ezahlukeneyo zenyanga
Phambi kokuqala ukuchaza izigaba zenyanga, kubalulekile ukugxininisa ukuba izigaba esiza kuthi sizibize ngegama kuphela kwendlela yokujonga inyanga ukusuka kwindawo esikuyo emhlabeni. Ngaxeshanye, ababukeli ababini kwizikhundla ezahlukileyo eMhlabeni banokubona inyanga ngokwahlukileyo. Akukho nto iqhubekayo kwinyani, umntu obukeleyo osenyakatho ye-hemisphere unokubona inyanga ngokuhamba ukusuka ekunene ukuya ekhohlo kwaye kwi-hemisphere esemazantsi isuka ekhohlo iye ekunene.
Emva kokucacisa oku, siqala ukuchaza izigaba ezahlukeneyo zenyanga.
Inyanga entsha
Ikwabizwa ngokuba kukuthwasa kwenyanga. Kule nqanaba, isibhakabhaka ebusuku simnyama kakhulu kwaye kunzima ukufumana inyanga ebumnyameni. Ngeli xesha, icala elikude lenyanga esingaboniyo likhanyiswa lilanga. Nangona kunjalo, obu buso abubonakali eMhlabeni ngenxa yokujikeleza okungqameneyo okukhankanywe apha ngasentla.
Kuzo zonke izigaba inyanga edlula kuzo, ukusuka kwindawo entsha ukuya kwezeleyo, isathelayithi ihamba nge-180 yeedigri yokujikeleza kwayo. Ngeli nqanaba lihamba phakathi kwe-0 ukuya kwi-45 degrees. Singakwazi kuphela jonga phakathi kwe-0 ne-2% yenyanga xa intsha. Iinkcukacha ezithe vetshe malunga noku zinokufumaneka apha I-Eclipses kunye nobudlelwane babo nenyanga.
Inyanga yeCrescent
Yinqanaba apho sinokufumana khona inyanga ihamba emva kweentsuku ezi-3 okanye ezi-4 emva kwenyanga entsha. Kuxhomekeke ekubeni sikuphi eMhlabeni siya kuyibona kwelinye icala lesibhakabhaka okanye kwelinye. Ukuba sikwi-hemisphere esemantla, siza kuyibona kwicala lasekunene kwaye ukuba sikwi-hemisphere esemazantsi siya kuyifumana kwicala lasekhohlo.
Kwesi sigaba senyanga kunokubonwa emva kokutshona kwelanga, ke ngoko uhamba phakathi kwe-45 nama-90 eedigri zokujikeleza kwawo kwesi sigaba. Ipesenti ebonakalayo yenyanga kolu khenketho yi-3 ukuya kwi-34%.
Ikota yekresenti
Kuxa isiqingatha sediski yenyanga sikhanyiswa. Inokubonwa ukususela emini emaqanda kude kube sezinzulwini zobusuku. Kweli nqanaba lihamba phakathi kwe-90 kunye ne-135 degrees of orbit yayo kunye siyayibona ikhanya phakathi kwe-35 kunye ne-65%. Ungafumana ngakumbi malunga nendlela inyanga ekuchaphazela ngayo ukuziphatha kwethu kwi eli nqaku linomdla.
Inyanga egxadazelayo
Indawo ekhanyayo ingaphezulu kwesiqingatha. Ibeka ngaphambi kokusa kwaye ifike kwincopho yayo ephezulu esibhakabhakeni ngongcwalazi. Inxalenye yenyanga ebonakalayo iphakathi kwama-66 kunye nama-96%.
Inyanga epheleleyo
Ikwaziwa ngokuba yinyanga epheleleyo. Sikwinqanaba apho inyanga ibonakala ngokupheleleyo. Oku kwenzeka kuba iLanga kunye neNyanga zihambelana ngokuthe ngqo noMhlaba kwiziko lawo.
Kweli nqanaba likwindawo echasene ngokupheleleyo nokuthwasa kwenyanga ngeedigri ezili-180. Ingabonakala phakathi kwe-97 kunye ne-100% yenyanga.
Emva kwenyanga epheleleyo, ezi zigaba zilandelayo zezi:
- Inyanga ebusayo
- Ikota yokugqibela
- ukuphela kwenyanga
Zonke ezi zigaba zineempawu ezifanayo neekresenti, kodwa igophe liyajongwa kwelinye icala (kuxhomekeke kumhlaba esikuwo). Ukuqhubela phambili kwenyanga kuyehla ukuya kufikelela kwinyanga entsha kwakhona kwaye umjikelo uqalile kwakhona.
Ndiyathemba ukuba ngolu lwazi izigaba zenyanga ziye zacaca.
