When we see a full moon, what does Russia sees?

Answer 1

Gary H is correct but says too little; zerobyte is off the mark.

The question is a little disconcerting since Russia is a vast country.

There are two sides to this question. The first is that the moon is close, so we get what is called a parallax effect. If two people in widely different places are looking at the moon at the same time (east to west) they see a slightly different phase. But this is usally meausured in hundredths of a percent.

The other side of the question is that the TIME ZONES are different. The lunar phases are actually calculated down to seconds of accuracy; the phases are either getting bigger or smaller; at times, during the "new moon" there is no phase at all that is visible (the dark side is completely turned towards us).

So if someone in Russia sees a "full moon" at the precise instant it is calculated, the issues is that by the time the U.S. gets to look at the same moon, it is 12 hours into the next phase. So it's not really the same, but is "mostly the same".

It's not the same if you're trying to catch a small detail on the side that is on the terminator or shadow line.

In point of fact in a telescope if you watch the moon you can watch the shadow line move (the terminator). So the phase is always changing, even though the basic four phases are new moon, first quarter, full moon, last quarter, and then new moon again etc. When the moon rises at night in one phase, or total % illumination, and it is in a slightly different phase (greater or smaller) when it sets later on.

So the people in the United States and Russia can never see EXACTLY the same phase, but it will be close, because a twelve or fifteen hour time difference is not a lot out of the lunar cycle.

But it is SOMETHING more than "nothing" of a difference. Someone with a telescope in Russia might find it easy to study a particular small crater (because of the terminator or shadow line, which throws all the features into black-and-white relief). But someone in the United States might have difficulty seeing the same crater, because it has either passed into full illumination (no shadows to bring it out) or into shadow (no light to see it).

On some craters you can see that the peak of the mountain in the center is illuminated, catching the last sunshine before the darkness either swallows the crater or the first rays of light before the whole crater is lit up.

So technically if we in the U.S. see a full moon EXACTLY TO THE SECOND Russia would have to wait about 12 to 15 hours (depending on where in Russia) and would actually see an older full moon that is already heading into last quarter.

Hope that helps.

Incidentally if you are in the SOUTHERN HEMISPHERE the moon looks upside down relative to the Northern hemisphere.

Answer 2

A full moon.

East / West do not affect the sky except for time. (i.e. the moon will have moved SLIIIIGHTLY across the sky in the time it takes for North America to rotate to the position where Russia was 10-12hrs ago, but not enough to make any noticeable difference in the Moon's phase).

Latitude is the main aspect of location which has an effect on how and what you see in the sky. In the southern hemisphere, the moon and equatorial constellations move across the northern sky, and appear upside-down from what you'd recognize in the northern hemisphere.

There are also constellations that never come above the horizon to the Northern hemisphere (such as the southern cross). The moon has the same phase down there, though, and between Australia and Argentina, things would look the same in the sky as between USA and Russia.

Longitude just means that one area is seeing it before another does. Eclipses do depend on longitude, but that's just because of time - these events are short enough that they may have passed by the time your part of the world gets there.

Answer 3

When I see a full moon, based on where I live, parts of russia see the sun, and parts of it see a full moon. But I think you mean when it is night in Russia, why moon do they see. Well, since the light reaching the moon from the sun, and the shadow caused by the earth, are not affected by where anyone lives, they see the same thing. There are very tiny differences in the in the exact shape of the moon (i.e., the visible part) at different locations on earth, but most people would not be able to detect them by eye alone.

Answer 4

The Moon is in the same phase at the same time as seen from everyplace in the world. So Russia sees a full Moon on the same day as we do.

Answer 5

A full moon.

C'mon. Think about it. The Moon takes about 28 days to go through all its phases. So it's in "Full" phase for a few days. The Earth rotates once a day, so night-time for the Russians will show the full moon too.

Answer 6

About 12 hours later, nearly the same full moon.

Answer 7

Daylight - Russia is on the other side of the earth and so is in daylight when we have night, and they have night when we are in daylight.
But that night in Russia they see the same full moon. We're all one planet, after all.

Answer 8

When the full moon is on the zenith at Manhattan, Kansas, it is high noon at Barnaul, Siberia. If, however, you live in Beirut, Damascus, Amman, or Jerusalem, people in Moscow see the same full moon you do, only lower in the sky to the South.

Answer 9

merely approximately an entire hemisphere of the earth can see the moon at every person time. there's slightly of the hemisphere around its component this is excluded, with the aid of curvature of the earth. For factors alongside a N-S longitude line, human beings can see the moon on an identical time.

Answer 10

Russia sees a last quarter.
