From what part of the Earth can you see both faces of the moon?
544347
You always see the same face, you can`t see the dark side.\n\nBut you can see the moon different ways up depending on where in the world you are...\n\ne.g. I live in the uk and am used to seeing moon a certain way up. When I travelled to Singapore the moon seemed to be on it`s side. When I went to Australia, the moon looked completely upside down.\n\nBut it was the same face.

The full moon is visible as full anywhere\non earth where it is above the horizon...\nobviously if it is far in the southern\nhemisphere and you are far north, like\nin northern Finland, you may not see the\nfull moon at all... (but if you could it\nwould still appear full)

Due to atmospheric interference, it would not be possible to see any mad made object left on the moon from a telescope on the surface of Earth.\nHowever, there is a very powerful, Earth orbiting, telescope which is free from atmospheric distortions…the Hubble space telescope.  However, even this telescope, as powerful as it is, could not possibly see the flag left on the moon.\n\nUsing a little math and common sense, it would not nearly be possible to see the flag on the moon with the Hubble space telescope.\n\nFirst, let’s get some basic facts straight.\nThe Diameter of the Hubble telescope is 2.4 meters and the distance from the Earth to the moon (on average) is about 3.84 E8 meters.\n\nPretty much the only thing limiting what Hubble can and cannot resolve is diffraction through a circular aperture (i.e. how light waves interact with each other when they get to Hubble's mirror.\nThe minimum angle which a circular aperture can resolve is given by the formula,\nTheta_min = 1.22 Lambda / D\nwhere Theta min is the minimum angle, Lambda is the wavelength of light we are using, and D is the diameter of the opening.\n\nIf we assume we are using light at 500 nm (roughly the middle of the visible spectrum) and we know that Hubble's diameter is 2.4 meters, we can find the minimum angle to be,\nTheta_min = 2.54 E-7 radians.\nThis is quite a small angle by Earthly standards, but will it compare to the angle to the flag on the moon?...we'll see.\n\nHere is where I have to make an assumption, but it is a very reasonable assumption and one that will assure us that out answer is correct. Watching the moon landing videos, one can see that the astronauts placed a moderately sized flag on a pole on the moon. Although I don’t know the exact dimensions of the flag, I can assure you, it was definitely no bigger than 10 ft. But for the sake of argument and to make the numbers easier, let’s assume it was 10 feet (~3 meters).\nIf the distance between the flag and Hubble is the same (about) as the distance from the Earth to the moon, then we can calculate the angle between the top of the flag and the bottom of the flag pole as seen by Hubble orbiting Earth. The angle comes out to be about, 7.81 E-9 radians, about 30 times SMALLER than the absolute minimum angle Hubble can resolve...and this is if we assume that the flag is 10 ft, which it obviously is smaller than that in reality.\n\nPlus, Hubble was specifically designed to look at VERY distant object. Although the moon is far away, it might as well be right next to us compared to the stars/galaxies/.. Hubble is supposed to be looking at. Therefore, I don’t know exactly how it will respond looking at such a close and bright object.\n\nOne this is sure through, you could not see the flag, even with one of the best telescopes ever built operating perfectly under ideal conditions using visible light.

The truth is, the moon obviously orbits the earth, right? So you look up and see the moon in the time of day, it is at an angle where other parts of the Earth can see it, sometimes the moon is here in the day time because it is on the same side as we are facing the sun, if it is during the night time, we see the moon because it has orbited behind the Earth, it takes the moon a certain amount of time to get around the Earth.

The most we can ever see is 59% ...\n\nRelative to the Earth, the Moon makes one rotation every 29.5 days. That happens to also be the time it takes for the Moon to complete one revolution around the Earth. This might seem like a coincidence, but it's not. \n\nIn the past, the Moon used to rotate much faster than it does now. But over millions of years, the effect of the Earth's gravity has slowed down the Moon's rotation until it became gravitationally locked to the Earth. This is why we always see the same side of the Moon. \n\nIt would seem logical to say that at any one time we can see 50% of the Moon's face. If the Moon were flat, that would be correct, however we know the Moon is a sphere. And the spherical shape of the Moon hides the area close to the perimeter and we can, at any one time, see only 41% of the Moon's face. \n\nEven though the same side of the Moon's faces us, we do see a bit more than half of the Moon's face. Over time, because of librations, we can see up to 59% of the Moon's surface. \n\nLibrations are irregular motions of the Moon in its elliptical orbit around the Earth. They are measured using longitudinal and latitudinal coordinates. Both are computed from a central point that is at a fixed geographical location on the lunar surface. This point is in the Sinus Medii, a small plain just below and to the right of he large rayed crater Copernicus. Two meridians emanate from this point: the Central Meridian runs north and south, and the Lunar Equator runs east and west. \n\nDifferent librations affect different sides of the Moon and each contribute added surface area. The added viewable surface area changes from day to day and month to month. Some librations overlap, but the maximum amount of lunar surface that we can see over time is 59%. \n\nThe longitudinal libration is produced by the elliptical orbit of the Moon. Because of the nature of the elliptical orbit, the speed of the Moon changes depending on which part of the orbit it is in. When moving from its fastest point (closest to Earth) to its slowest point (farthest from Earth,) the Moon's speed is slowing down. But, because the Moon's rotational speed stays the same, for a period of time the Moon's face is not pointed directly at us, and this "lag" effect allows observers to see an extra bit of the lunar surface. In effect, we are "peeking" around the edge of the Moon! When the Moon is one quarter of the way around the Earth, it is 97 degrees through its rotation. \n\nThis libration is called longitudinal because the extra surface areas exposed are along the lines of longitude (perpendicular to the equator.) The total extra surface area we can see from longitudinal librations is about eight degrees. \n\nThere is also a libration that is latitudinal. The plane of the Moon's orbit is titled 5 degrees to the ecliptic. For half the lunar cycle, the Moon is above the ecliptic and for the other half it is below the ecliptic. Each of these half cycles expose an extra bit of the Moon. The extra surface area shown during these librations is at the top of the northern hemisphere or the bottom of the southern hemisphere. The total extra surface area we can see from latitudinal librations is almost 7 degrees. \n\nThere is one more librations called Diurnal Librations. This librations occurs every day. Observers can "see" over the top of the Moon as it is rising. Likewise they can see under the bottom when it is setting. Diurnal librations are caused because the radius of the Earth adds an extra 4000 miles of height for looking "over" or "under" the Moon when it is on the horizon. This daily libration gives us an extra one percent of lunar surface area for viewing.

Google has programs that do that for the earth and the moon but you will have to download some software to do it right and your computer will have to be fast, check it out.

Earth.  But one of them is not a true moon.  It's only a temporary one.

You can see about 4 miles to a flat horizon on the Earth. So from one horizon to the other would be 8 miles. (On the Moon, it would only be 3 miles-- the horizon is only a mile and a half away.)

No.  The moon would alwayd be full if you were on the sun, because the sun's light illuminates the moon.  You would, howvere, be able to see the side of the moon that is never possible to see from the earth (which we incorrectly call "the dark side of the moon").

It reflects the light of the sun.  What on the moon could possibly produce light?  There's no fire, nuclear reactions, or anything of the like going on there.  Want to prove it yourself?  Go outside on a day where you can see both the moon and the sun in the sky.  Take a good look at the phase of the moon.  Which side of the moon is lit up?  The side facing the sun, since the moon is reflecting the sun's light.

The plane of the orbit of the moon is close to the plane of the ecliptic, so the curve of the earth takes you a little bit closer to the moon in the tropical regions.  Therefore: Hawaii.\n\nBut it's not a big effect---not big enough to be noticable by eye.  The moon appears almost the same size from everywhere on earth.

Think of it this way.  The earth has 4 sides, just because ONE OF THEM is looking at the moon and the Sun is facing another side, means nothing.  There is over 90,000,000 miles between the earth and the sun, so we only get a fraction of a percent of its total output of energy.  The Moon while it is in space going around us, is no longer "blocked" by the earth and can now receive its share of light from the sun.  HOWEVER, you may be surprised to learn that the albedo (reflection of light) from the moon is mostly caused by the Earth as much as the Sun.  That is, where it is now daylight on Earth is relecting off of the moon also.

The moon is there, don't worry. Sometimes, yeah, you can see the people on the moon. Squint properly.

It rotates on its axis once per month. If you could stand on the sun, you would see all sides of the moon in the course of a month. Also, if you could stand on Mars you would see all sides of the moon in the course of a month. The "single face" issue arises because we on earth are right in the middle of it--as the moon rotates on its axis once per month, it also revolves about the earth at the same speed, always showing the same face to the earth.\n\nSince the moon does not always show the same face to the sun, there is no "dark" side of the moon. All parts of the moon get equal amounts of sunlight, just as all parts of the earth do. There is a "far" side to the moon, the side that is always facing away from earth.\n\nAnother way to think of it is to think of the flagpole planted by astronauts. It of course is pointed toward the earth at all times. At the time of new moon (when the moon is between the earth and the sun), the flagpole is pointed toward the earth and the outer solar system, toward the realm of Mars, Jupiter, and Saturn. At the time of full moon (when the earth is between the sun and the moon), the flagpole is pointed toward the earth and the sun. Obviously the moon rotated so as to bring the flagpole from pointing to the outer reaches around to pointing toward the sun.\n\n\nFor Dirty Idea (below): ask your question as a Yahoo! question and maybe I'll look it up for you. I think it has to do with tidal locking. It's not a coincidence at all.

A full moon is simply fully visible.  Usually, the earth is between the sun and the moon to some degree.  The curved shadow on the moon is the shadow of the earth.  A full moon is when the moon is slightly to the side of the earth and the sun is shinging on the entire surface with no shadow of the earth on it.\n\nSee the link below for a good explanation.

The rotation of the moon just happens to be in the same sync as its orbit around the earth, so we only see one side. From the looks of the moon, though, it's speculated that the moon may have orbited faster or rotated faster, etc because there are crater marks on the earth side also, just not as many.\n\nActually, the moon is locked in its orbit so it always faces the Earth. The Moon is NOT perfectly round...technically its shaped like an egg due to the effects of gravity from the earth and possibly too when the moon was formed bilions of years agao after a huge meteor crashed into the earth and some of the Earth's molten core spewed out into space. Because the Earth is more massive than the Moon, it pulls on the Moon, "stretching" it closer to the Earth, throwing the shape and axis off, causing the moon unable to rotate on its own axis. This same effect is seen by the moons of other massive planets like Jupiter and Saturn. The same is effect is also seen with Mercury due to its close proximity the Sun and its massive gravitational effects.
