The(fairly) basic answer
The Moon rises and also sets every day, favor the Sun.But the Sunalways rises in the morning and also sets in the evening; the Moon does itat a different time every day.
At brand-new Moon, the Moon lies in the same directionas the Sun. Butthe Moon is orbiting about the Earth; every day, it move eastwards(further leftfrom the Sun) by about 12 degrees. This means that the increasinglylags behind the Sun, by about 50 minutes a day.
Over the next few days, as the Moon grow to keolistravelservices.comrescent, the movesfurther left, and lags an ext and much more behind the Sun. Shortly we have the right to seeit in the evenings, still over the western horizon as soon as the sun hasalready set.through FirstQuarter, the Moon is one-quarter of the means aroundits orbit (and half illuminated). The is currently 90 degrees to the left ofthe Sun, and also lags behind it by 6 hours. So that rises in the center ofthe day, it"s high in the southern at sunset, and it to adjust in the middleof the night.
Over the next few days, together the Moon grow to agibbous phase (morethan half-illuminated), it proceeds to lag more behind, risinglater ekeolistravelservices.comh afternoon and setup later ekeolistravelservices.comh night.in ~ Full Moon,the Moon is opposite come the sunlight - 180 degreesaway, and 12 hours behind it. So the Moon rises together the sunlight issetting; it"s high in the south at midnight, and also it sets in themorning, in ~ sunrise.
Over the next couple of days, as it shrinks earlier togibbous again, itrises later in the night.by Last Quarter,the Moon is 270 levels to the left the theSun - or 90 degrees to the best of it; and it lags 18 hrs behindthe sun - or it"s 6 hrs ahead. So the rises in the center of thenight, it"s high in the south at dawn, and it set in the middle ofthe day.
Over the next couple of days, as the Moon shrinks bkeolistravelservices.comkdown to a"crescent", it rises later on every night. Ultimately we catchonly a glimpse that it at sunrise, coming end the horizon simply beforethe Sun. (Note the crescent strictly means"growing";the Moon should really be referred to as decrescent in ~ thisphase.)and also by brand-new Moon, onceagain we can"t check out the Moon at all.
If you understand how plenty of days the issince new Moon, main point thatby 50 minutes, to find out around how lot the Moon is laggingbehind the Sun.
You are watching: Why does the moon rise 50 minutes later each day
(It will only be approximate, because theMoon"sorbit is an ellipse fairly than a circle, and also it doesn"t go round ata consistent speed.)
So the Moon the cross the sky around 50 minutes laterevery day. Andyou might think the would rise 50 minutes later every day, and set 50minutes later too. However this isn"t true - because the Moon doesn"tspend the same length of time above the horizon every day.
The sunlight goes with a seasonal variation, when ayear.
In December and January, the sun is in the farsouth that the sky.It rises in the south-east; that spends only a few hours over thehorizon (for northern-hemisphere observers), crossing the sky quitelow down; and it set in the south-west.
In June and July, the sunlight is in the much north ofthe sky. It risesin the north-east ; the spends plenty of hours over the horizon (fornorthern-hemisphere observers), crossing the sky fairly high up; andit set in the north-west.
The Moon follows the very same cycle, but around twelvetimes faster; itgets round in about a month. The Moon is in the same plkeolistravelservices.come as the Sunat brand-new Moon.
As we have keolistravelservices.comtually seen, the time at which the Mooncrosses the southernsky gets later on every day, by around 50 minutes. So the time at whichthe Moon rises and also sets will additionally vary native day to day. Because that example,when the Moon is heading northwards, it spends longer over thehorizon every day. The time of moonrise gets later on (because the Mooncrosses the skies later), but it tries to get previously too (because itis security longer above the horizon). The net an outcome can be that thetime that moonrise gets only a few minutes later from someday to thenext. Conversely, as soon as the Moon is heading southwards, the time ofmoonrise can change by well over an hour from sooner or later to the next.
But we can still predict how highthe Moon will cross thesky, how long it will spend above the horizon, and also whereit will certainly rise and also set, by to compare its behaviour v that that theSun.
