29.5 days
The pattern of the moon phases repeats approximately every 29.5 days, known as a lunar cycle or synodic month. This is the time it takes for the moon to go through all its phases, from new moon to full moon and back to new moon again.
8 phases.
The changes in shape that the moon goes through are called phases.
It takes one month for the Moon to go through all of its phases one time.
The moon has different phases that it passes through, just like we have different phases in our lifetimes.
From the perspective of the earth, the most apparent objects that go through phases are the moon, Venus and Mercury
A complete cycle - for example, from one full moon to the next - takes 29 1/2 days.
All but one. The cycle of phases of the Moon takes 29.5 days, so however you define the length of a lunar phase, you're missing one.
On average 29.53 days
No, we see the same side of the moon as it orbits and goes through phases because the moon rotates at the same rate it orbits.
No, the moon's phases are caused by the changing angles of sunlight hitting its surface as it orbits Earth. The moon does pass through Earth's shadow during a lunar eclipse, but this is a separate astronomical event from the moon's phases.
