If it takes the moon 27.4 days to complete one orbit about the Earth, why does it take 29.5 days between a full moon to full moon cycle? Any mathematical proof would be helpful, thanks.
The moon takes approximately 27.3 days to orbit the Earth. This is known as its sidereal period, which is the time it takes for the moon to complete one orbit around the Earth relative to the stars.
No, the moon's orbit is not a perfect circle. It is slightly elliptical, meaning that its distance from the Earth varies slightly throughout its orbit.
The moon's orbit is longer than the Earth's rotational period because the Earth's gravitational pull affects the moon's orbit, causing it to move slower than the Earth's rotation.
No, the moon's speed varies throughout its orbit. It moves fastest when it is closest to the Earth (perigee) and slowest when it is farthest away (apogee).
The moon's phases are a result of its position in relation to the Earth and the sun. It takes approximately 29.5 days for the moon to complete all of its phases, known as its synodic period.
