By, um, looking at it. You'll probably need a telescope, and you'll have to observe it for a considerable period of time (several months at least) to notice much of a change.

As the moon moves around the earth what does an observer on earth see?
He sees the phases of the moon. A varying amount of the sunlit surface is visible as the moon goes through its phases, having increased or decreased illumination with a curved boundary.
Why do planets have phases similar to lunar phases?
The planet Venus has phases similar to the moon's phases because of its orbit around the sun, inside the orbit of the Earth. Because of its particular orbit, an observer from the earth is?æable to see various phases.
What phases do you see when the moon is at a right angle to side the earth and sun?
full moon
Is there a relationship between moon phases and earth phases?
Yes. If you're standing somewhere on the moon's half-surface that always faces the earth, then the earth is always in your sky, and you see it go through a cycle of phases every 29.53 days, just as the moon does in our sky. But the shapes of the phases that the earth displays to an observer on the moon are exactly opposite the sequence of shapes that we see the moon display. The result is that the illuminated portion of the moon in earth's sky, plus the illuminated portion of earth in the moon's sky, always add up to exactly one fully illuminated disk.
What are the phases of the moon and what causes the moon to appear to change?
The phases of the moon are The phases of the moon appear to change because the earth rotates on it's axis and the moon orbits the earth. The sunlight hits a different part of the moon that is visible to us. Half of the moon is always lit up, you just can't always see it.
How the moon would appear to an observer in space during its revolution. Would phases be observable?
Yes. Unless the observer was on the back side of the moon, or on the opposite side of the earth from the moon, he/she could see the same phases that we see here on earth.
As the moon moves around the earth what does an observer on earth see?
He sees the phases of the moon. A varying amount of the sunlit surface is visible as the moon goes through its phases, having increased or decreased illumination with a curved boundary.
Why would an observer on the Earth see a complete cycle of the phases of the moon in approximately one month?
because of the tilt of both the moon and the earth on their rotation axis
What are the various phases of the Earth?
The apparent 'phases' of the earth depend entirely on where the observer is located. If the observer is standing on the moon and looking at the earth, he will see the earth go through exactly the same phases as we see the moon go through ... but they will be COMPLEMENTARY. At any moment of the month, the shape of the ILLUMINATED portion of the moon ... seen from earth ... is exactly the same as the DARK portion of the earth as seen from the moon. Combine the illuminated moon phase of the earth-bound observer with the illuminated earth phase of the moon-based observer, and they always add up exactly to one full illuminated disk.
Can you see the moon phases in space?
The phases of the moon are caused by the relative positions of the sun, the moon and the observer. It is possible to see phases of the moon in space depending on your position relative to the sun and the moon.
To an observer on the moon able to see earth how long would one full cycle of earth phases be?
It would be about 29.5 earth days. Or, precisely the same length of time as a full cycle of moon phases.
What changes of the moon do you see from Earth?
The phases of the moon as it orbits the earth
The phases of the moon depend on how much of the lighted side of the moon can be seen from earth?
From earth we see the same side of the moon but depending on the position of the moon, earth, sun we see different portions of the moon- these are known as the phases of the moon.
Why we see the different phases of the moon from earth?
The phases are caused by the angle that the sunlight strikes the moon.
What is the definition of the moon phases?
The phases are the different shapes that the Moon seems to have when it is observed from Earth. This is due to the location of the Moon in its orbit, so that we only see a portion of its surface as illuminated by the Sun.
Would you see phases of the earth from the moon?
Yes.
What is a moonless period called?
If you are referring to lunar phases, there are two phases in which the moon is not visible to the earth. In the New Moon and Dark Moon lunar phases, the moon is not visible to those on earth. See related links for more information.
