How many days does t take for the moon to do 1 rotation on its axis?

Answer 1

this depends on what you mean. for the moon to return from one phase to the same (for example new to new or full to full) it takes 29.53059 days (29 days, 12 hours, 44 minutes and 3 seconds).

this accounts for the rotation of the earth. so for all intents and purposes as viewed from the earth's surface- this is the best answer. if you watch and measure from anywhere on earth, this is the duration of one lunar orbit.

the nodal month, which is the duration the mood takes to travel from one node of its orbit to the same node is 27.21222 days.

this is 'one complete trip' as viewed from anywhere outside the earth as it does not take into account the rotation of the earth. http://wiki.answers.com/../How_many_days_does_it_take_for_the_moon_to_make_a_complete_trip_around_the_earth#ixzz1A02N0O7I

Answer 2

Approximately* 27.32 days.

Related Information:

The moon makes one complete orbital revolution of the earth in 27.32 days,

and displays a complete cycle of phases every 29.53 days.

The 27.3 day cycle is the length of time it takes for the moon to get back to its starting point, relative to the fixed stars. This orbital period (once around the earth) is called the moon's sidereal period. It is very similar to the concept of the earth's sidereal day (once around the sun) being a few minutes shorter than 24 hours of universal time.

The phase cycle of the moon requires 2.2 days more to complete than the sidereal period, because this cycle is relative to the sun. The difference is due to the fact that the moon must travel a little beyond its sidereal period to complete its phase cycle, since the earth is also moving in its orbit around the sun.

If you measure from full moon to full moon, you will come very close to 29.5 days. However, by the time that the second full moon is observed, the moon will have already made a little more than a full orbit around us. There are about 13.4 sidereal orbits of the moon around the earth each year.

Remember that sidereal periods are shorter than moon cycles as given by phases, so that's approximately the length of a leap year (366 days).

Answer 3

From the point of view of an observer on Earth, the moon appears to revolve

around him once every 27.32 days.

From the point of view of an observer on the sun, the moon appears to revolve

around him once every 365.25 days on the average.

Answer 4

The Moon is in synchronous rotation: it rotates about its axis in about the same time it takes to orbit the Earth - 27.3 days. This results in it nearly always keeping the same face turned towards the Earth.

Answer 5

Moon revolve around the earth in 27.3 days

Answer 6

The Earth does not move around the Moon, the Moon moves around the Earth.

Answer 7

The moon is continually in the process of revolving around the earth.

It completes one full revolution every 27.32 days.

Answer 8

365 days and a quarter. The Moon orbits the Sun together with the Earth.

Answer 9

The moon makes one complete revolution of the earth in 27.32 days,

and displays a complete cycle of phases every 29.53 days.

Answer 10

The moon completes one rotation on its axis, and also completes

one orbital revolution around the earth, in 27.32 days. (rounded)
