Why does the full moon sometimes looks orange when it rises?
541440
It is the same reason that sunsets are red and orange. The sun is shining all of the colors of the rainbow on to the moon, and the moon is reflecting all of those colors pretty evenly. Actually during Harvest moon this happens and also one can see this on any full or nearly full moon as the moon is rising.\nWhen the moon is low, the reflected sunlight has to travel through more air than when the moon is high in the sky. Colors at the blue or violet end of the rainbow(spectrum) are easily scattered or bent(refracted) by the atmosphere. (That's why the sky is blue: you're seeing blue sunlight scattered in every direction.) So it's the colors at the red and orange end of the spectrum that pass through the atmosphere and into your eyes.\nFor more info on the moon visit http://www.madison.k12.wi.us/planetarium/mooncal/moonfaq.htm

It is an optical illusion.  The moon appears to be larger because you are comparing it to smaller things.  They have taken very careful measurements and determined that, in fact, the moon is the same size no matter where it is in the sky.\n\nThere was a theory for a while that the moon appears larger because objects in general appear larger when you look horizontally at them.  I have to admit I have a soft spot for that theory no matter how hare-brained it may seem.  After all, your heart jumps when you look down (and maybe up?) a long cliff, but you don't get the same effect when you imagine the same situation in a horizontal context.  I've heard this theory was mostly debunked, so I can't seriously suggest it anymore.

The shape of the moon does not actually change, but it is the shadow of the earth that gives the illusion. The moon revolves around the earth due to which we have full moon, no moon and half moon periods as it travels betweeen the shadow of the earth. During the period from no moon to full moon, the earth is in between the moon and the sun due to which the earth's shadow falls directly on the moon and thus we cannot see the illuminated part of the moon.As the earth graduallly moves away from the position, we can see the illuminated part of the moon which appears in the shape of a crest.  Also due to the non existence of atmosphere on the moon, there is distinct difference in the illuminated and the dark part of the moon. During the period from full moon to no moon, it again moves from the shadow of the earth and thus at one point is completely overshadowed by the earth and doing the disappearing act.

While refraction by the atmosphere is too small to affect the apparent diameter of the moon except perhaps when it is within one diameter of the horizon (and in this case, the moon will appear stretched a bit in the direction perpindicular to the horizon) it does appear larger to our brains when on the horizon because we see it in reference to distant large objects.  Gives the impression of it looking bigger, however if you could look straight up at the moon, and see a bunch of trees a mile up in sky between you and the moon it would look just as large as when it is near the horizon.  (If you ever do see this by the way, seek shelter or psychiatric treatment immediately!)\n\nThe moons orbit IS elliptical, however, and at times will be closer to the earth than others.  This phenomenon is called "lunation" and there is a great still and a gif animation of this at the Astronomy Picture of the Day.\n\nhttp://antwrp.gsfc.nasa.gov/apod/ap041021.html\nhttp://antwrp.gsfc.nasa.gov/apod/ap991108.html\n\nThe moon's surface brightness (brightness per area) also varies with phase. Because larger particles tend to reflect a bit more light directly back at the light source than in other directions (look up "Mie" scattering) a given bit of the moon will appear brighter when the earth is in the direction of the sun as seen from the moon. (All three are in a line with the Earth more or less between). This occurs when the moon is full or near full. This brightening might make the moon look larger.

The moon is visible all over the world (not just the Western hemisphere).  In a 24 hour period the moon will be above the horizon for 12 of those hours.  Depending on where the moon is in it's orbit relative to the sun determines when it is visible in the day.  \n\nNew moon is when the moon is nearest the sun, and full moon is when it is furthest away.  That is why a full moon is really only visible at night.  \n\nFirst quarterr moon rises about noon and sets about midnight.  Last quarte moon rises about midnight and sets around noon.\n\nThe moon is brighter than the sky at daytime and so it is visible even against the blue sky of a sunny day.

"Half Moon" simply refers to that moment in the lunar cycle haflway between the New Moon and the Full Moon.  It doens't necessarily refer to the way it looks like.

Assuming that the moon is at a location visible from both Greece and Texas, which is entirely possible, then yes you will both see a full moon.  If not, then Greece will see a full moon as soon as the moon rises for them.\n\nBut chances are, you are asking about the "fullness" of the moon from different terrestrial vantage points.  Then the answer is still yes, because what people perceive to be a "full" moon is subject to a very wide margin of visual ambiguity.  The moon can be "not quite full" by several degrees and still appear perfectly full and round to the human eye.  This is what lets us see a full moon for an entire night, and in fact most of the time, for several nights in a row.\n\nIf our visual acuity were able to discern the lit versus dark surface of the moon under more strict contrast (much, much more strict), then for most of that time we would see the tiniest sliver of dark and perceive the moon as not-quite-full.  The closer our vision approaches to perfect (and the more perfectly transparent our atmosphere becomes), then the less amount of time we would believe the moon were truly full.\n\nEventually, and technically, the moon can only be truly full for a fraction of a second, but then it would only be so during the peak of a lunar eclipse, which rather takes away from its "fullness", haha.  This is the instant that the moon is perfectly opposite the Earth from the sun.

Depends on atmospheric conditions ,small water droplets form into ice crystals in the upper atmosphere. The moon reflects light into these droplets causing refraction of that light, givind a halo effect sometimes even a 'luna rainbow'

As the Moon moves along its orbit around the Earth its hemisphere toward the sun is fully illuminated.\n\nBut from the Earth we see only the hemisphere that is turned toward us.\n\nThat is, we are not seeing that hemisphere which is fully illuminated by the Sun.\n\nThat is why we see different shapes which are called phases of the moon.\n\nIn new moon day, the moon is in between Sun and Earth, and the moon’s non illuminated hemisphere is toward Earth and in the back ground of Sun’s bright light, the moon is invisible.\n\nWhen Moon is at 90 degree from the Sun, half of the illuminated hemisphere of Moon is visible from Earth. \n \nWhen Moon is at 180 degree from the Sun, full of the illuminated hemisphere of Moon is visible from Earth. We call it as Full Moon.

One meaning to this is that you did not check the archive of previously asked questions before you posted your question about the sky's color. This has been asked and answered almost 400 times so far here (see link below). \n\nHowever, the reason the sky appears blue (at least most of the daylight hours) is that the atmosphere is mostly oxygen and nitrogen, which are just the right size molecules to scatter the blue light, but let the other colors pass unimpeded. \n\nSo when you take the blue away from the mostly white sunlight, you get sorta yellow sunlight. \n\nAs the sun sets, the sunlight passes through more air, and more blue is scattered away, leaving the sunlight even less blue, that is, more orange. \n\nAs the sun sets even farther, even more blue is scattered away, and the sunlight appears red.

First of all i would like to say that you are some kind of good thinker.. well for 4 years old, this kind of question may too complex for you. But i try to answer it for our knowledge.\n\nWell the moon is not just go down when the sun is up. The world is rotating itself, while the world is rotating around the sun. In the same time, the moon is rotating around the earth and the sun. When you are at any part of the earth expecially near to the equator, you will see some kind of nice organized pattern of when sun is out, the moon is gone, otherwise vise versa. \n\nWell, actually this is not the true. The moon is still there rotating around the earth in 24 hour time, but when the part of the earth where get alots of sun shine, the brighness of the moon will dissphere like you shine a touch in a good shinine day. The light from the touch will not seen as in the dark. But we cannot say that the ligh is gone. The light is still there but, due to the brigher light of the sun (higher cendela - unit for light), the reflaction light of moon is not seen.\n\nThere are some infomation that i can help you. It's good to think!!!

Moses and Campbelp have it right--the fluorescent light is closer and of larger apparent size (especially if it is a long tube!).  The sun's shadows are not perfectly sharp because it has some size.  This is the cause of the "penumbral" lunar eclipse, when the moon dims but is not fully eclipsed, as it passes through the dim but not dark portion of the Earth's shadow (the penumbra--the darkest part of a shadow is the umbra).

The color! When the moon is more yellow than white, it is considered to be a "bad moon" when the lunatics are more likely to come out and cause problems.\n\n\n(lunatics derives from the latin word Luna which is the moon, lunatics are followers of the moon that traditionally would cause havoc and chaos only during the full moon)

the moon generally appears larger when it is near the horizon. It works by the fact that you have something to compare it too. The same moon that night way up high in the sky obviously would look smaller as there is nothing to compare it too.\n\nThere is one fool proof way to prove this. When the moon is near the horizon stick out your arm and cover the moon with the tip of your pinkie. Do it again when the moon is overhead, you'll soon see it is the same size.

It's an optical illusion which is commonly referred to as the "Moon Illusion", meaning it's true for the moon also...\n\nThe most common misconception is that it is because you are unconsciously comparing the Sun to foreground objects like trees and houses, or even the horizon itself, and that makes the Sun look bigger than when it is all alone in the sky. This turns out to be false. As it happens, there are already excellent descriptions of this effect on the web. Probably the best is by Donald Simanek, Professor of Physics at Lock Haven University of Pennsylvania, and another very good one is by Carl Wenning, from the Illinois State University.\n\nI've also see some nonsense about it being because it's seen through a "thicker slice of atmosphere", which if it were true it would make the Sun look smaller!\n\nIn addition, you have probably seen that the rising or setting Moon looks very red. This is the same reason the sky is blue...

Also, we only see it when it is above the horizon.\n\nDuring the day, the sun is obviously above the horizon.  But the moon sets an hour or so later each day, so sometimes it is below the horizon in the day, and sometimes not.

The seawater simply reflects the light ..at dawn iit is orangish as the sky is orangish at noon light blue and in the night it is deep blue \nthe reason why the sky turns orange in the morning and evening is explained by raielings law of scattering
