That depends on your frame of reference: are you outside the solar system "fixed to the distant stars, or on the Earth looking up? The Moon makes a complete orbit around the Earth every 27.32 days (relative to the distant stars); 29.53 days (with respect to the Sun); 27.32 days (with respect to the "vernal point on the ecliptic - where the Sun crosses).
The Moon is in synchronous rotation, which means it rotates about its axis in exactly the same time it takes to orbit the Earth, thus always showing the same side to obvservers on Earth (or just about - it does wobble a little so 58% of the surface was mapped before spacecraft photographed the far side of the Moon).
What else can I help you with?
Why do you have half and full moon?
Due to the phases of the moon and rotation of the Earth.
How does the moon slow Earth's rotation and how does the Earth change the moon's orbit?
The Earth-Moon gravitational interaction that produces the tides is gradually slowing the Earth's rotation. So, the Earth loses angular momentum. That causes the Moon to gain angular momentum. The acceleration of the Moon causes its orbit to slowly get larger. See "related links" below. In the link, look for the headings "Tidal Braking of the Earth" and "Lunar Recession".
What is the period of rotation for Luna?
The period of rotation for the Moon (Luna) is approximately 27.3 Earth days. This means it takes about 27.3 days for the Moon to complete one full rotation on its axis.
Why do planets moons have moons rotation?
I will assume you mean "why do the moons of planets rotate?" this is because the moon has mascons (mass concentrations). these mascons are attracted by the planet more than the rest of the moon, so these parts of the moon always face towards the planet, meaning that the moon rotates
How the rotation of earth will be affected it its density becomes uniform?
If Earth's density becomes uniform, its rotation would likely remain unaffected. The rotation of Earth is primarily influenced by external factors like the sun and moon, as well as the planet's angular momentum. Changes in density distribution within Earth's interior would have minimal impact on its overall rotation.
What is making the moon move far away?
The law of conservation of angular momentum. The earths rate of rotation is slowing due mainly to the drag of the tides caused by the moon. To conserve the angular momentum in the earth/moon system the moon has to recede. The moon isn't moving.
What is the angular diameter of both the sun and moon?
The angular diameter of the sun is about 31 to 32 arcminutes, which is roughly the same as the full moon.
Why do you have half and full moon?
Due to the phases of the moon and rotation of the Earth.
Is the moon an angular distance from the sun increasing or decreasing during waning phases?
During the waning phases of the moon, the angular distance from the Sun is generally increasing. This is because, as the moon transitions from a full moon to a new moon, it moves away from the Sun in the sky, resulting in greater angular separation. Consequently, the waning phases reflect the moon's orbit around Earth, causing this increasing angular distance.
How does the moon slow Earth's rotation and how does the Earth change the moon's orbit?
The Earth-Moon gravitational interaction that produces the tides is gradually slowing the Earth's rotation. So, the Earth loses angular momentum. That causes the Moon to gain angular momentum. The acceleration of the Moon causes its orbit to slowly get larger. See "related links" below. In the link, look for the headings "Tidal Braking of the Earth" and "Lunar Recession".
What is it that the phases of the moon depends on?
The phase of the moon depends on the rotation of the moon. A full moon gets full sun. A new moon is on the other side of the earth from the sun.
What is the period of rotation for Luna?
The period of rotation for the Moon (Luna) is approximately 27.3 Earth days. This means it takes about 27.3 days for the Moon to complete one full rotation on its axis.
How long does the moon rotate?
The moon is always rotating. It completes a full rotation every 27.32 days.
Are all full moon the same?
The appearance of full moons tend to vary in size. This is an optical illusion caused by the Earth's rotation and the distance between Earth and the Moon at the time of the full moon.
Which is bigger full moon or crescent moon?
The diameter of the Moon doesn't change. The apparent (or angular) diameter changes a little, depending on the distance of the Moon from Earth, but this is not directly related to the phases of the Moon.
How long does it take the moon to make a full rotation on its axis?
27.3 days.
How often do you see the far of the moon?
You never see the far side of the moon. Somewhat coincidently the moon has an angular rotation as the earths rotation, and therefore the same side of the moon is always facing earth. The far side is never seen. To the extent that the rotations are not exact, there may be a slight variation over many, many years.
