Iinkqubo zenyanga ne Eclipses
Shenxisa iNyanga ejikeleze ihlabathi kwaye ubone indlela yayo ukusuka kwihlabathi, kunye nokuba xa ii-eclipses zingaba khona.

Iinkqubo zenyanga ne Eclipses
Yintoni le? The Moon makes no light of its own. The Sun always lights one half of it, and as the Moon travels round Earth, about once every 29.5 days, we see more or less of that lit half. Those changing shapes are the phases.
Indlela yokusetyenziswa kwayo: Rhuqa i "Iintsuku ukusuka namhlanje" umtya wokudada, okanye nqakraza Dlala. Imboniselo enkulu ijonge ezantsi kwihlabathi nenyanga ukusuka phezulu kakhulu; umfanekiso omncinci ubonisa ilanga njengoko ungalibona ukusuka kwihlabathi.
Inyanga namhlanje
Inyanga epheleleyo Elandelayo: Inyanga Entsha Elandelayo:
Imboniselo evela phezulu
Imboniselo evela kwihlabathi
Ibonakala kwi-hemispheric yasempumalanga iNyanga ijikeleze phantsi xa kuthelekiswa nombono wasempuma, ngoko ke icala elikhanyayo lijika.
Zama oku
- Rhweba ngaphakathi Iilayini Zeqela leenkwenkwezi e GeminiIsaziso: Le yinyanga entsha. Ingxenye ekhanyayo ijonge kude nathi, ngoko ke asiboni nto; inyanga ikwilanga lemini, ilahlekile kwilanga eliqaqambileyo.
- Keep going about 15 days, to full Moon.Isaziso: Ngoku ihlabathi liphakathi kwelanga nenyanga kwaye sibona yonke inxenye ekhanyayo. Inyanga epheleleyo inyuka xa ilanga liphuma kwaye liphezulu yonke imini.
- Nqakraza Dlala kwaye ujonge umyalezo phantsi kwamanani kwinyanga nganye entsha nepheleleyo.Isaziso: Iinyanga ezininzi akukho xesha lokungqubana: indlela yenyanga ijikelezwe ngamaqondo angama-5°, ngoko ke ihlala idlula ngasentla okanye ngezantsi kwesithunzi. Ukungqubana kwenzeka kuphela kwi "ixesha lokungqubana", malunga neenyanga ezisibhozo.
- Khetha "Ndihlala kwi hemisphere esempuma".Isaziso: Umfanekiso ujika phezulu nobucala. Ukusuka eAustralia okanye eArgentina inyanga ekhanyayo ikhanya ngasekhohlo, hayi ngasekunene.
Iimbono ezimva kwayo
Kutheni sibona iimeko?
Ukukhanya kwelanga kwibhola emnyama yegumbi kwaye uhambe kuyo: ukusuka kwezinye iindawo ubona yonke inxalenye ekhanyayo, ukusuka kwezinye kuphela isiqhamo. Ilanga lilanga, inyanga yibhola kwaye ukwihlabathini phakathi. Inqanaba alinanto yokwenza nesithunzi sehlabathi; oko kubaluleke kuphela ngexesha lonyaka omnyama.
Sources: Moon phase from J. Meeus, Astronomical Algorithms (2nd edition, 1998), chapters 47 to 48; eclipse screening from chapter 54. Next new and full Moon dates are computed from the same formulas and are accurate to within about half a day.
How much of the Moon's sunlit half we can see from Earth. It changes from nothing (new Moon) to all of it (full Moon) and back in about 29.5 days.
Ukunyuka kuthetha ukunyuka: okuninzi kukhanya yonke imini, ukusuka kwinyanga entsha ukuya kwinyanga epheleleyo. Ukuhla kuthetha ukuncipha: ukusuka kwinyanga epheleleyo kwakhona ukuya kwinyanga entsha.
Inyanga ejikelezayo ingaphantsi kwengxenye yelanga, isiqwenga esincinci esigobileyo. Inyanga ejikelezayo ingaphezulu kwengxenye yelanga kodwa ayikho igcweleyo.
Ininzi kangakanani na i Moon' s face, njengoko siyibona ukusuka kwihlabathi, ikhanya yi Sun. 50% yinyanga ephindwe kabini; 100% yinyanga epheleleyo.
The number of days since the last new Moon. A full cycle of phases takes about 29.5 days.
Okuninzi kwincwadi eneenkcukacha →Xa iqulethe ilanga lenye. Kwi eklipsi yelanga inyanga ivala ilanga; kwi eklipsi yelanga inyanga idlula kwisithunzi sehlabathi kwaye ijikeleza ibe mnyama okanye ebomvu njenge coppery.
Okuninzi kwincwadi eneenkcukacha →Enye yeencopho ezimbini okanye indawo ekuyo i Moon' s ejikelezayo indlela i crosses iplanethi ye Earth 's indlela jikelezo i Sun. Eclipses kuphela iza kwenzeka xa entsha okanye i Moon liwela phezulu kwi node.
