What's a lunar cycle ?
-- If you use a star in the sky as a marker, the moon passes it every 27.32 days.
-- If you go by the phases of the moon, the time between two occurrences of
the same exact phase is 29.53 days.

∙ 14y agoYes actually.
The time between two full moons (and between successive occurrences of the same phase) is about 29.53 days (29 days, 12 hours, 44 minutes) on average (hence, the concept of a timeframe of a period of time of an approximated month was derived). This synodic month is longer than the time it takes the Moon to make one orbit about the Earth with respect to the fixed stars (the sidereal month), which is about 27.32 days. This difference is caused by the fact that the Earth-Moon system is orbiting about the Sun at the same time the Moon is orbiting about the Earth.
The second full moon of the month is called a blue moon.

∙ 11y agoA complete cycle of phases for the Earth, if you're on a part of the Moon where you can see it (for someone on the Moon, the Earth doesn't appear to rise or set, it just sort of wiggles in place unless it's right on the horizon, in which case the wiggle might make more or less of it visible).
Wiki User
∙ 15y agoIt is false, unless you consider 28 to be close enough to 27.32, the true orbital period of the moon. The synodic period (the period which is in synch with the observed moon phases) of the moon is 29.53 days. The large difference between these two periods is counter-intuitive and not easily understood, but it is real. The sidereal orbit of the moon around the earth, the orbit as it would be observed from far to the north of the solar system, and the orbit as it would be defined relative to the distant stars, is the orbit of 27.32 days. But remember that as the moon orbits the earth, the earth is also in the process of orbiting the sun. So the moon has to move around the earth a little longer than 27.32 days in order to 'catch up' with where it was relative to the earth and the sun. That is why the cycle of moon phases, the synodic orbit, is 29.53 days even though a true sidereal orbit happens every 27.32 days.

∙ 13y agoThe Moon takes 29 days 12 hours and 44 minutes (29.53 days) to display
the full range of all possible appearances, or "phases".
Wiki User
∙ 13y agoThe moon orbits the earth once each 27.32 days.
The complete cycle of phases is seen from earth once every 29.53 days.
Which of those cyclic phenomena is puzzling you ?
Wiki User
∙ 12y agoit's because it takes 28 days for the earth's moon to orbit the sun.
Wiki User
∙ 13y agoA full cycle (for example, from full moon to full moon) is about 29 1/2 days, on average.
Wiki User
∙ 11y agoAbout once. The Moon rotates once in 27.3 days.

The time it takes for the moon to revolve around the earth is approximately?
28 days.
Are the Moon's phases caused by Earth's rotation?
No. The phases of the Moon are caused by our moon rotating around the Earth. When the moon is between the Sun and Earth, the face nearest to us is not illuminated and in the Moon's own shadow, and this aspect we call 'New Moon'. When the moon is on the side of Earth farthest from the sun, it is fully illuminated, and this we call 'Full Moon'. [Due to the distribution of mass in the moon, it keeps one face towards Earth.] The earth rotates once every 24 hours, so we see the moon in our sky once a day - but sometimes in the daytime - when it is approaching 'New'. But the moon orbits the earth once every 28 days (approx) and this motion is the one that is responsible for the phases of the Moon. !
Is your calendars based on earth's orbit of sun or the Moon's orbit of earth?
Most calendars are based on the Earth's movement round the Sun. The Gregorian calendar is used in most countries and it has 365 days in a year, with an extra day (February 29) in 97 years out of every 400, which are called leap years. This gives an average year of 365.2425 days.
Is there going to be a new moon?
Visually, that is correct, most of the time. The new moon happens when the moon is directly between the earth and the sun. So without very special equipment, it cannot be seen. However, this is the time when eclipses of the sun happen, and during eclipses we 'see' the moon eclipse the sun. We don't see very much detail; we see the moon in the sense that we don't see what the moon is blocking.
What is the period of time it takes the moon to revolve once around the earth called?
It takes 27.32 days. It has no particular name other than the moon's 'orbital period'. It takes 29.531 days for the moon to display a full cycle of 'phases'. That's the origin of the 'month'.
How many days are there between each full moon?
about 28 days. This happens roughly every month. (month -> moon)
Is there a full moon about every 28 days?
no
How many time in a month do you see a new moon?
Every two weeks there abouts. A full moon is every 27-28 days but a half moon is every 14 days but if you want to know about just the time the half is on the right side then that is once every 27-28 days.
In what phase is the moon when you do not see it?
The phase in which the moon is not visible from earth is called the "new" moon. It happens when the moon is aligned between the sun and the earth (every 28 days), which causes the side of the moon that we usually see to be in shadow.
Do the moon orbits the earth 28 times every month?
The Moon orbit the the earth every 29.5 days.
How often do you see a full moon - everyday every twenty eight days or every year?
every 28 days
When does the last quarter moon show up?
About every 28 days
How quickly does the moon rotate?
about one rotation every 28 days
How rare is a moon shadow?
A moon shadow occurs every 28 1/2 days.
How often do the moon phases repeat?
Every lunar month. Which is approximately every 28 days.
What is the duration of one day moon?
The moon rotates once on its axis once every 28 days.
What is the duration of one day on moon?
The moon rotates once on its axis once every 28 days.
