Concerning the lunar month of approximately 29.53 days as viewed from Earth, the lunar phase or Moon phase is the shape of the Moon's directly sunlit portion, which can be expressed quantitatively using areas or angles, or described qualitatively using the terminology of the four major phases (new moon, first quarter, full moon, last quarter) and four minor phases (waxing crescent, waxing gibbous, waning gibbous, and waning crescent).
The lunar phases gradually change over a synodic month (c. 29.53 days) as the orbital positions of the Moon around Earth, and Earth around the Sun, shift. The visible side of the Moon is variously sunlit, depending on the position of the Moon in its orbit, with the sunlit portion varying from 0% (at new moon) to 100% (at full moon).
Each of the four major lunar phases is approximately 7.4 days±19 hours (6.58–8.24 days), the variation being due to the elliptical shape of the Moon's orbit.
Muonekano wa dunia yetu ikiwa katika hali ya Crescent Earth ni sawa na ile hali inayotokeaga kwenye mwezi wetu baada ya sehemu fulani ya mwezi wetu kukosa mwanga wa jua.
Katika dunia yetu huwa kuna pande mbili ambapo huwa na utofauti moja huwa na mwanga na nyengine hukosa mwanga ambapo upande...
