Yimaphi amaphuzu abalulekile ngokuphathelene nokushona kwelanga okwenzeka eNyangeni embhalweni onikeziwe?
Context:Ukufiphala kwenyanga kuyisenzakalo sezinkanyezi esenzeka lapho iNyanga ingena emthunzini woMhlaba, ibangele ukuba inyanga ibe mnyama. Ukuqondaniswa okunjalo kwenzeka phakathi nenkathi yokushona kwelanga, cishe njalo ngemva kwezinyanga eziyisithupha, phakathi nesikhathi senyanga egcwele, lapho indiza yomjikelezo wenyanga iseduze kakhulu nendiza yomjikelezo womhlaba. Lokhu kungenzeka kuphela uma iLanga, uMhlaba, kanye neNyanga kuqondaniswe ngokunembile noma eduze kakhulu (e-syzygy) noMhlaba phakathi kwezinye ezimbili, okungenzeka kuphela ngobusuku benyanga egcwele lapho iNyanga iseduze nenye yama-lunar node. Uhlobo nobude bokusitheka kwenyanga kuncike ekusondeleni kweNyanga ku-lunar node
1. Izinkomo Lapho iNyanga ingena emthunzini woMhlaba, okwenza ukuba inyanga ibe mnyama kwenzeka isenzakalo sezinkanyezi esaziwa ngokuthi ukusitheka kwenyanga. 2. Izingelosi Lapho umjikelezo wenyanga useduze nomhlaba, phakathi nesikhathi sokugcwala kwenyanga, kuba khona ukusitheka kwenyanga. 3. Izindaba Ezinhle Ukufiphala kwenyanga kungenzeka kuphela lapho ilanga, umhlaba, nenyanga kuqondaniswe kahle noMhlaba. 4. Izidakamizwa Uhlobo nobude bokusitheka kwenyanga kuncike ekutheni inyanga iseduze kangakanani ne - node yenyanga.
