27.3 days to make a whole revolution. It also takes 27.3 for the moon to revolve on its axis.
About 27.3 days.
24hoursAs the moon always shows the same face to the Earth, would not a day on the moon be infinitely long?
Because the moon is tidally locked with the Earth its period of revolution is the same length as its orbit -- approximately 28 days.
It varies between 27.3 and 29.1 days. with a mean of about 28.5 days. The reasons for these time differences are the Moon's elliptical orbital track about Earth, and thereby the strength of gravitational attraction between the two bodies. Also the gravitational attraction due to the Sun. When at solar perigee gravity is strongest, so nearer and faster, at solar apogee gravity is weaker, so further away and slower.
A mean period of Lunar Revolution/Orbit is 28.5 days. Fastest is 27.32 days Slowest is 29.1 days
the earths moon helps sustsian the gravity on the earths oceancs keeping them in balance
About 27 days, in both cases.
27.32 days
To correct your English . . It is not 'moon period; , but 'LUNAR Period'. 'Lunar is the adjective, and comes from Latin for Moon , which is 'Luna'. The Moon revolved/orbits the Earth once every 28.5 days as a mean period. Fastest revolution is 27.32 days and slowest revolution is 29.1 days.
the moon
The moon doens't rotate (from earth's perspetive). We always see the same side of the moon.
