The Moon completes its orbit around the Earth in approximately 27.3 days (a sidereal month). The Earth and Moon orbit about their barycentre (common centre of mass), which lies about 4700 km from Earth's centre (about three quarters of the Earth's radius). On average, the Moon is at a distance of about 385000 km from the centre of the Earth, which corresponds to about 60 Earth radii. With a mean orbital velocity of 1.023 km/s, the Moon moves relative to the stars each hour by an amount roughly equal to its angular diameter, or by about 0.5°. The Moon differs from most satellites of other planets in that its orbit is close to the plane of the ecliptic, and not to the Earth's equatorial plane. The lunar orbit plane is inclined to the ecliptic by about 5.1°, whereas the Moon's spin axis is inclined by only 1.5°.

Why does the Earths orbit?
Moon and earth distance
How does the movement of Earth and the Moon's orbit causes the phases of the moon?
the earths blockage of sun light
Is the moon speed constant?
The moon has an elliptical orbit around the Earth, although it is almost circular; when the moon is at the closest point to the Earth in its orbit, it moves the fastest, and when it is at the most distant point, it moves the slowest. But the variation is relatively small.
What happens when the moon moves into earths shadow?
That's when we have a lunar eclipse.
Which is greater the moon's pull on earth or earths pull on the moon?
The moon is only strong enough to push and pull the tides in the ocean on earth. The earths pull is so strong it moves the entire moon in circles.
Which is larger the earth or the earths orbit?
the earths orbit because the earths orbit is the size of earth + the size of the moon
Is the moon in earths orbit?
Yes.
Is the earths orbit around the sun a cause of the phases of the moon?
No. The moon's orbit around the earth is.
What is the earths axis parallel to?
orbit of the moon
Is held in its orbit by the Earths gravity?
the moon
Why does the Earths orbit?
Moon and earth distance
What is the path in which the moon moves around the earth?
The ORBIT of the Moon.
What keeps the earths moon in orbit?
gravityy brew XD
How does the movement of Earth and the Moon's orbit causes the phases of the moon?
the earths blockage of sun light
How does Earth has gravity?
the earths gravitational pull keeps the moon in orbit
Is the earth's natural satellite the sun?
no, the moon is the Earths natural satellite, the moon is in orbit around the Earth. The whole Earth/Moon system is then in orbit around the sun.
Why isn't there 2 eclipses every time the moon orbits the earth?
Because the sun, moon and earth are not always in alignment. The moon does not orbit the earth about the earths equator. The earths axis is tilted so the orbit around the sun does not always align with that of the moons orbit around the earth
