About 27 1/2 days.
Moon approximately take 27.3 days to complete one rotation around earth
it takes approximately 29 and one thirds days.
The moon completes an orbital revolution around earthand a rotation on its own axis both in 27.32 days.
It is called synchronous rotation when the rotation and orbit take the same amount of time.
Moon's rotation on its axis, and revolution in its orbitaround the earth, are both 27.32 days.
Moon's rotation on its axis, and revolution in its orbitaround the earth, are both 27.32 days.
Moon's rotation on its axis, and revolution in its orbitaround the earth, are both 27.32 days.
The moon completes one orbital revolution around the earth in 27.32 days. The moon also completes one rotation on its axis in exactly the same time.
Like Earth's moon, Deimos' axial rotation is synchronous with its orbital revolution as a satellite of Mars. The period of both motions is 30.3 hours.
That's not called "rotation", but "revolution". A full revolution is about 27 1/2 days; divide this by four to get the average time for a quarter revolution.
27.3 days.
Yes, but that's not the whole story. The moon's rotation on its axis and its revolution relative to the Earth take the same number of days, hours, minutes, seconds, and any small fraction of a second you want to consider. They are synchronously locked, and precisely equal.
