Buri 29.53 umunsi, mukaaga itera cycle yose y'impamyabwenge — bivuye iny nshya itasiboneka kugera full mukaaga ubwenge n'ubwiyunge. Izo mpamyabwenge ziyabikubikira ubuhinzi, ubwiyunge, n'amakamineza kugira iminsi mibiriti ivugire. Ava, Moon Phase Calendar ikugufasha kusezerano impamyabwenge yo yose hamwe na igihe cyizabwa cyane kubarira kwa astrophysique algorithms.
Se mukaaga ifite impamyabwenge
Iny mukaaga ntiyakora kuwala — igaruka kuwala kw'inya. Pomwe mukaaga igukirira inya, iciro cyose cy'ubwenge bwikunzwe ziyakona kubacu, bivutsa impamyabwenge.
Ku gihe kiciro, thaka rimwe ry'ubwenge rimwe bikundikira na Jyambere (iciro kikwakwa Jyambere). Impamyabwenge tutubona dutegekezamo ku kugira angle pakati py'inya, inya, n'iny mukaaga. Pomwe mukaaga ari pakati py'inya n'inya, turowera iciro ciyatazira — iny mukaaga nshya. Pomwe inya ari pakati py'iny mukaaga n'inya, turowera iciro cyuzuye — iny mukaaga yuzuye.
Impamyabwenge 8 z'Lunar Cycle
New Moon — Iny mukaaga ari pakati py'inya n'inya. Iciro cyuzuye nzira kuri kibazo cyatutsi, mukaaga itasiboneka (0% ubwenge). Umu bivutsa umunsi 0 w'cycle ya synodic.
Waxing Crescent — Umukakasa w'ubwenge ukarikira mu kuva kwa mukaaga (Northern Hemisphere). Ubwenge bukura bivuye 0% kugera 50%. Crescent mukaaga bikunzira kuroboneka binyuma y'inya.
First Quarter — Thaka rimwe ry'iciro cy'ubwenge rimwe bikundikira (50%). N'ubwacu "quarter," thaka rimwe riwoneka — bivutsa "first quarter" mukaaga igice cya quarter cy'inazo.
Waxing Gibbous — Hejuru hejuru y'ubwenge, bukura kugera full. "Gibbous" ivanicyo Latin "hump."
Full Moon — Iciro cyose cyuzuye (100%). Mukaaga ukaruka inya iyo inya ikaruka, bivutsa itasiboneka yose. Umu bivutsa ~Day 14.8.
Waning Gibbous — Ubwenge bukira kuva full. Iciro cyuzuye ciyakira mu kuva.
Last Quarter — Thaka rimwe riwoneka ndiponso (50%), nubwo hejuru heringiwe. Mukaaga ari itatu-quarter yo mu cycle.
Waning Crescent — Umukakasa w'ubwenge ukariraka, atiboneka kumwambo kutangira Jyambere. Cycle ndipo ivuguruka nshya mukaaga.
Synodic Month
Impamyabwenge yose — bivuye iny mukaaga nshya kuri ijayo — bivutsa synodic month, igeza 29.53 umunsi (29 umunsi, 12 isaha, 44 dakika). Umu utandukanye na sidereal month (27.32 umunsi), rigihe mukaaga ituma inya guhera inya.
Synodic month nderuha bivuye ibintu mukaaga izungurira inya, inya nayo izungurira Jyambere. Mukaaga ifuna zaka ~2.2 kubwira angle ya Jyambere-inya-mukaaga.
Impamyabwenge z'iny mukaaga n'Tides
Impamyabwenge z'iny mukaaga bikigira neza tides ku burundi. Ndi new moons n'full moons, inya n'iny mukaaga bigarukira, n'ubwiyunge bwazo bikora tidal ranges bikunzira spring tides. Ndi quarter impamyabwenge, inya n'iny mukaaga ari angles, pang'ono bikanakana ubwiyunge bwazo, bivutsa tidal ranges bitazira neap tides.
Ubu gravitational interaction nayo bivutsa mukaaga kugenda paliponse bivuye inya — gutuzuza 3.8 centimeters buri myaka — n'se Earth rotation imandera pang'ono.
Kugenzura Impamyabwenge z'iny mukaaga
Moon Phase Calendar ku isi rino ibarana igihe cyizabwa cy'impamyabwenge hakoreshwa Meeus astrophysique algorithm. Ushobora kurowera illumination percentages buri munsi, igihe cyizabwa cyose cya major phase events, n'umunsi w'ubwenge bwa mukaaga. Kugira nkizo ubwiyunge bw'kubarira kubishyira mu mubanza, reba How Lunar Time Is Calculated.
