Izinsuku zenyanga nezingqimba
Hambisa inyanga ejikeleze iplanethi futhi ubone indlela yayo evela kuplanethi, kanye nosuku lapho ukunyakaza kwelanga kungase kwenzeke khona.

Izinsuku zenyanga nezingqimba
Yini lokhu? Inyanga ayikhiqizi ukukhanya kwayo. Ukukhanya kwelanga kuhlala kungenxa yaleyo nhlamvu, futhi njengoba iMhlaba ihamba ngaphesheya kweplanethi, cishe izikhathi ezingu-29.5 ngosuku, sibona ngaphezulu noma ngaphansi kwaleyo nhlamvu ekhanyayo. Lawa mafomu ashintshayo yimijikelezo.
Indlela yokusetshenziswa kwayo: Dlulisa i-"Days from today" slider, noma chofoza Play. Umbono omkhulu ubheka phansi ezweni kanye nenyanga kusuka phezulu kakhulu; isithombe esincane sibonisa inyanga njengoba uyibonayo kusukela ezweni.
Inyanga namhlanje
Inyanga egcwele elandelayo: Inyanga entsha elandelayo:
Ukubuka kusuka phezulu
Ukubuka kusuka eMhlabeni
Uma ubona kusuka enyakatho yezwekazi ilanga libheke phezulu uma kuqhathaniswa nendawo yokubuka yasenyakatho, ngakho-ke ingxenye ekhanyayo ishintshiwe.
Zama lokhu
- Dlulisa kuze kube uLwezi luhlala phakathi kwe-Isihlabathi nelanga.Isixhumanisi: Le yinyanga entsha. Ingxenye ekhanyayo ibheke phambili, ngakho-ke asibona lutho; inyanga iyizulu lemini, ilahlekile emlilweni welanga.
- Qhubeka uqhubekela phambili ngezinsuku ezingu-15, kuze kube yinyanga egcwele.Isixhumanisi: Manje i-Earth iyiphakathi kwelanga nenyanga futhi sibona inhlamvu egcwele. Inyanga egcwele ikhula njengoba ilanga liphuma futhi liphezulu yonke imini.
- Chofoza Dlala bese ubheka umlayezo ngaphansi kwamanani ngaso sonke isikhathi sonyaka omusha nonyaka ogcwele.Isixhumanisi: Inyanga eminingi ayikho i-eclipse: indlela yenyanga ihamba ngokuyi-5°, ngakho-ke ivame ukudlula phezulu noma ngaphansi kwesithunzi. I-eclipses ikhona kuphela "isikhathi se-eclipse", cishe ngaso sonke isikhathi sonyaka omibili.
- Khetha "Ngihlala enyakatho ye-hemispheric".Isixhumanisi: Isithombe sishintsha phansi. Ku-Australia noma e-Argentina uLwezi omnyama ukhanya ngakwesobunxele, hhayi kwesokudla.
Izinhlamvu ezimqoka
Kungani sibona amaphaseji?
Shintsha i-torch kwibhola egumbini elimnyama bese uhamba eduze kwayo: kusuka kwezinye izindawo uzobona yonke inhlamvu ekhanyayo, kusuka kwabanye nje isibhakabhaka. Ilanga yi-torch, inyanga iyibhola futhi ukhona emhlabeni phakathi. Isigaba asikho isizathu sokwenza nesithunzi sezwe; lokhu kubaluleke kuphela ngesikhathi sokunyakaza kwenyanga.
Amasu: Isigaba senyanga kusuka ku J. Meeus, Astronomical Algorithms (isibuyekezo sesi-2, 1998), iziqephu ezingu-47 kuya ku-48; ukuqapha kwe-eclipse kusuka kusiqephu esingu-54. Izimo ezintsha zenyanga kanye nezimo ezigcwele zibalolwa kusuka kuzifomula ezifanayo futhi zilungile ngaphakathi kosuku oluphakathi.
Ingabe ingxenye ekhanyayo yenyanga singabona ngayo kusuka emhlabeni. Ishintsha kusuka kulutho (inyanga entsha) kuya kuyo yonke (inyanga egcwele) futhi ibuyela emuva cishe ngezinsuku ezingama-29.5.
Ukuncibilika kusho ukukhula: kukhanya kancane ebusuku, kusukela ngenyanga entsha kuya ngenyanga egcwele. Ukuncipha kusho ukuncipha: kusuka ngenyanga egcwele emuva kuze kube nenyanga entsha.
Inyanga ekhulayo incane kunengxenye ekhanyayo, inqwaba encane ejikelezayo. Inyanga eyisicaba ingaphezulu kwengxenye ekhanyayo kodwa ayikho egcwele.
Ingabe ingxenye enkulu yelanga, njengoba siyibona kusuka emhlabeni, ikhanya yilanga. 50% iyinyanga engxenyeni; 100% iyinyanga egcwele.
Inani lamasonto kusukela ngenyanga entsha yokugqibela. Isigaba esigcwele sithatha cishe amasonto angama-29.5.
Okuningi ku-glossary →Uma ilungu elinye livala ukukhanya kwelinye. Ku-eclipse yelanga, uLwandle luvala ukukhanya kwelanga; ku-eclipse yenyanga, uLwandle ludlula isithunzi sezulu futhi lushintsha ube mnyama noma obomvu obubomvu.
Okuningi ku-glossary →Enye yezingxenye ezimbili lapho indlela ejikelezayo yenyanga idlula khona iplanethi yendlela yezulu ejikeleza uLwandle. Izinkanyezi zingaba khona kuphela uma inyanga entsha noma egcwele iwela eduze kwe-node.
