How long does it take the moon to orbit the earth?

Question

:]

Answer 1

It takes the moon anywhere from 27-30 days to orbit the Earth.

Answer 2

There are several ways to consider how much time it takes the Moon to complete one orbit. The sidereal month is the time it takes to make one complete orbit with respect to the fixed stars, which is about 27.3 days. In contrast, the synodic month is the time it takes the Moon to reach the same phase, which takes about 29.5 days. The synodic period is longer than the sidereal period because the Earth-Moon system moves a finite distance in its orbit around the Sun during each sidereal month, and a longer time is required to achieve the same relative geometry. Other definitions for the duration of a lunar month include the time it takes to go from perigee to perigee (the anomalistic month), from ascending node to ascending node (the Draconic month), and from two successive passes of the same ecliptic longitude (the Tropical month). As a result of the slow precession of the lunar orbit, these latter three periods are only slightly different than the sidereal month. The average length of a calendric month (1/12 of a year) is about 30.4 days.

Answer 3

About 28 days.

Answer 4

1 Lunar Month...

or about 28-30 days.

Answer 5

There are several definitions of a lunar month. The most common reference is the synodic month. But the three most common are listed below.

A sidereal month, from a fixed point in space like a star, is 27.32 days.

A synodic month, from new moon to new moon, is 29.53 days

A anomalistic, month from perigee to perigee, is 27.55 days

Answer 6

28 days.
