The moon orbits the earth in such a way that the same side of the moon is facing towards the earth at all times. A fancy way of describing this is that the moon rotates once when it orbits the earth once.
Rocks returned from the Apollo lunar landings are made of the same material as the rocks on earth. Scientists now believethat the moon was created when another object slammed into the earth back when the earth was still very hot and had a much thinner crust. The moon is a combination of the earth at that timeand the object that hit us. That is why the moon rotates once with evey revolution.

Is the moon orbit an example of a parabola?
No. Every closed orbit (around and around and around) is an ellipse. Every open orbit (swish by one time and never return) is a hyperbola. The one that's exactly precisely on the dividing line between closed and open is a parabola.
What is one radian?
It is the derived unit of plane angle and 1 radian = one full rotation/2π. Also, it is equal to 57.296°.
When a planet revolves around a star in an elliptical orbit is the star one of the two foci of the ellipse?
All ellipses have two focuses, or "foci". For the Earth's orbit, the Sun is at one focus of the Earth's orbit. There isn't any physical object at the other focus of the Earth's elliptical orbit.For the Moon, the Earth is at one focus of the Moon's orbit.
What is the path of one object circling another?
orbit orbit orbit
What are all right angles?
Right angles are ninety degree angles. That is equal to one quarter of a complete rotation.
How does the moon rotate to keep one face pointed toward the earth?
The moon's rotation has become synchronized with its orbit. During one orbit it makes one full revolution. The moon almost certainly had a day and night at one time, a billion or more years ago. Over time, tidal forces reduced the moon's rotation until it slowed enough to keep one face to earth at all times.
You see only one side of the moon because one full rotation takes the same amount of time as one full?
orbit.
How does the Moon's rate of rotation about its own axis compare with its rate of revolution around Earth?
This has to do with the different orbital planets of Earth and the Moon. Earth revolves around the Sun in flat planar orbit. The Moon similarly revolves about Earth in flat planar orbit. But the planets are slightly tipped with respect to each other - a 5.2* tilt The moons rotation on its axis is equal to its orbit round the Earth with respect to the sun and stars. It presents one side permanently to the Earth so in relation to the earth it does not rotate.
Does the moon orbit around itself?
The moon rotates around its own axis, but revolves around the earth. The moon completes one rotation with each revolution around the earth, so one day on the moon (sunrise to sunrise) is equal to one month on earth. This coincidence is the reason only one side of the moon is always facing the earth.
How long deos it take for the moon to orbit the earth?
The moon completes one orbital revolution around the earth in 27.32 days. The moon also completes one rotation on its axis in exactly the same time.
What is the one rotation on the Moon's axis?
Since the moon always has the same side facing earth -- has always been so, I guess? -- one rotation is equal to one revolution around the earth, so about 28 earth days.
What State is at which the moon orbital and rotational periods are equal?
A state of `synchronous rotation`. Its where the rotational period of the moon is equal to orbital rotation period about Earth, one face of the moon will always appear to face earth. In our moons case this is due to tidal locking.
Why astronomers don't seen the back of moon?
Its own rotation keeps pace with its orbit in such a way that only one "side" faces the Earth.
Why is one day on the moon a year?
A day is time that elapses during an astronomical objects (in this case a moon) complete rotation around its own axis.A year is time that elapses during objects complete rotation around its parent object (in our case its a planet Earth) which holds it in its orbit by gravitational force.A day and a year on the Moon (Earths natural satellite, not any natural satellite) are almost equal in their duration, thus we may say that "one day on the moon is a year".
How many days will it take the moon complete one rotation?
Any single point on the moon experiences 14.77 days of sunlight followed by 14.77 days of darkness. While the moon is tidally locked to Earth, and always faces the earth, its period of rotation matches its period of orbit around the Earth.
Are orbit and rotation the same?
no. orbit is when something goes around somehing else, like the earth going around the sun. rotation is when spins, like a top.
Do any moons orbit earth?
Yes. One moon orbit Earth (The moon)
