How long does it take the moon to complete its phases?

Answer 1

The lunar cycle requires about 29 1/2 days (29.531 days). This is longer than the actual time it takes to orbit the Earth and to make a complete rotation (which are the same time). This is because the Earth and Moon are orbiting the Sun, the light from which is reflected by the Moon and observed on Earth.

Answer 2

it takes the moon 27.3 days to complete both phases

It takes 29.5 days for the moonto go through all the phases - from full moon to full moon. :)

Answer 5

one moon phase is just under a month, so probably in the area of 85 days

Answer 6

The moon takes the same time to rotate on its axis - as it does to orbit the Earth... 28 days.

Answer 7

A full cycle - for example, from one full moon to the next - is approximately 29 1/2 days.

Answer 8

28 (just about)
