When does the moon rise and set (approx)? Is it always there in the day time? How come its 8:22 and the moon?

To understand how the moon rises and sets you need to be aware that the moon rotates around the earth and that the moon and the earth, together with all the other planets, rotate around the sun.\n\nIt takes 24 hours for the earth (complete with the moon) to rotate around the sun.  The actual time is closer to 24 hours and 57 seconds but that's by the by.\n\nObviously each morning the sun rises and each evening it sets again - it's very much the same with the moon only the moon doesn't work on a 24 hour cycle.\n\nThe time it takes the moon to make a complete orbit around the earth varies depending on the time of year but it averages 24 hours and 50 minutes.  If the moon were to set today at 1.00pm then it would set tomorrow at 1.50pm, 2.40pm the next day and so on.\n\nDepending where you are on the planet the moon will rise and set at differnt times.  The moon rise times for the next few days in New York and LA are...\n\nMonday  11.39 in NY,  09:07 in LA\nTuesday  12:33 in NY,  10:03 in LA\nWednesday  13:33 in NY,  11:02 in LA\nThursday  14:37 in NY,  12:02 in LA\nFriday  15:41 in NY,  13:02 in LA\n\nAll times are PST\n\nSo in some ways the moon is similar to the sun in that it's always there but it's not always visible because it's around the other side of the earth.\n\nOften the moon is in the sky during the daytime (as it will be for the next few days) but it's not clearly visible as it's so dim in comparison to the sky.

what? I don't think the moon appears stationary since it travels across the sky and goes through phases.\nWhat?

no it is a reflection of the suns light.  That is why you can still see the moon during the day soemtimes.  It is still getting light from the sun.

One of the biggest misconceptions about the Moon is that its phases are caused by the Earth's shadow. The Earth's shadow causes eclipses, but it has nothing to do with phases. Rather, the phases of the Moon are produced by the alignment of the Moon and the Sun in the sky. \nThe orientation of Sun and Moon determines the phase of the Moon. At new moon, the angular distance of the sun and moon is small, less than a few degrees. At first quarter, when the moon is half full, the Moon lies 90 degrees east of the Sun. As an example, if you were to point to the setting sun with one arm and to the moon with the other, the angle between your arms would be 90 degrees. At full, the moon is 180 degrees from the sun and at last quarter, it is 90 degrees west of the sun. \n \n\nThe new moon is essentially invisible because it is between the earth and sun and therefore lost in the glare of the sun. Even on day 2 or 3 it is tough to spot the moon because it is just the tiniest sliver and still very close to the sun. The waxing crescent moon grows till it is about half full in the phase we call first quarter. From there it grows to full moon and then begins to shrink back to third quarter, waning crescent and finally back to new moon. \n\nThe first and last quarter moons mark the halfway points between the new moon and full moon. The first quarter moon is illuminated on the right hand side. The last quarter moon is illuminated on the left hand side. It seems conflicting to call a half full moon first of last quarter, but the quarter refers to the position of the moon in the sky, not it's phase. A quarter moon is one quarter of a full circle (90 degrees) away from the sun. \n\nThe lighted part of the Moon always points the way to the Sun. This means that a waxing crescent moon in the western sky at sunset has the lighted part on the right which is the direction of the Sun. The sequence of the lunar phases always proceeds with the lighted part of the Moon growing from right to left until the moon reaches full. After full moon, the light recedes from right to left until new moon. \n\nThe line boundary between dark and light on the Moon is called the terminator. It is rarely an even line because the surface of the Moon is not smooth. The terminator is closest to a straight line at first and last quarter. Librations affect exactly what portion of the face of the Moon is facing the Earth, during first and last quarter phase, the terminator's exact location may vary. This is illustrated when the terminator does not line up with the Moon's meridian at first and last quarter. In other words, you'd think that during first and last quarter when the Moon is half full, that the meridian (the imaginary line which runs from north to south on the Moon,) would be right on the terminator, but it isn't so. In fact the terminator can be almost 8 degrees off to either side of the meridian.

If the sun and the moon are both visible at the same time, then the first answer of course would be daytime.  However, for the moon to be visible during the day, it has to have risen somewhere in the 6 am - 6pm range.  this means that the moon can be in any phase from new moon through first quarter and almost to full moon.  So, the final answer to the question would be that when the sun and moon are both visible, it is called daytime during the first half of the lunar cycle.

This sounds oddly like a homework question!  \n\n:-)\n\nYes, the moon does move farther back each year. It is measured by timing laser pulses fired from earth at the laser reflectors left on the moon by Apollo missions. They time how long it takes to travel to the moon and back, which gives the current distance.\n\nIf this is homework, you'll also want to include why this happens. Think about what happens on the earth that is influenced by the moon. If you live near the ocean, the answer will be obvious. If not, think about the tides. Raising that much water is work. And there must be a balancing change somewhere else. ("Every action has an equal and opposite reaction"  ---Google for that phrase and Newton)\n\nThe net result is the earth's day is slowly getting longer and the moon's rotation is getting slower, which means the moon gets a little farther away each year.\n\nHope this helps\n\nChuck Taylor\nhttp://groups.yahoo.com/group/lunar-observing/

Dec 31 3:12 (GMT) Greenwhich mean time was a new moon. That would be sometime in the afternoon on Dec 30 in CA.\n\nhttp://sunearth.gsfc.nasa.gov/eclipse/TYPE/moonphase.html

Neat Question!!!!\n\nHere's your answer:\n\nIf the Moon disappeared then the tides would reduce in strength by about two thirds. There would still be tides, because the Sun causes tides, too (see the Conjunctions Page). \n\nThe Moon keeps the angle between the rotation axis of the Earth and the plane of the orbit of the Earth within a fairly narrow range, so that the strength of the seasons cannot differ too much from its current value. If the Moon disappeared, then the inclination of the rotation axis of the Earth would vary much more over periods of thousands of years and could get much further away from the upright position, with corresponding greater differences between summer and winter, and hence with great influence on the climate, such as Mars has experienced (without any large moon). See http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1993Natur.361..615L, http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2002A%26A...384..689E and http://arxiv.org/abs/astro-ph/0112399 (for http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2001EM%26P...85...61B). \n\nI've heard of kinds of animals that synchronize some rhythms of their lives with the phases of the Moon, and the sudden disappearance of the Moon could cause trouble for them. I believe I've heard of some kinds of turtles that come to lay their eggs on the beach at a certain Full Moon, and that the nightlife of deer and similar animals takes the phase of the Moon into account. In any case, fishermen and hunters seem to take the phase of the Moon into account, but perhaps that is because they would like to be able to see something at night. I am not a biologist, fisherman, or hunter, so I do not know the details of this. \n\nIt is highly unlikely that the Moon will just disappear. Only the very close passage of a celestial object of the size of a planet could wrench the Moon from the grip of the Earth's gravity, and such an event could also change the orbit of the Earth itself markedly, so then the disappearance of the Moon might not be the most important thing. Calculations of the future of the orbits of the planets show that such an event will not happen during the coming thousands of millions of years (at least not with one of the other planets of our Solar System as the disturbing object).

When the moon is full, it is on the side of the Earth opposite the sun. It takes the moon about a month to go around the Earth once. So in the course of a single day, it remains in almost the same position.

Starting with the full moon - A day or two before the "full moon" you will see the moon rise just before sunset. At full moon it will rise as the sun sets, and of course after the sun sets as the time goes on. Each night after, notice how the light on the moon shrinks from full to last quarter and then to nothing (a 2 week time period).  Also during this time you will notice the moon "traveling" closer to the sun. Two weeks from full moon (day may vary) look for the sliver of the moon just before sunset.  As the moon moves into NEW moon and you cannot see at all, watch for it to become noticable as a sliver in the other direction asa the sun sets. Follow the light on the moon as it expands to first quarter and then to full. So you can actually see the moon and the sun at the same time virtually most of the month.

You want exactly 8:23 but didn't say what time zone. At 8:23 am UT, which is the same as Greenwich Mean Time, the Moon was 62.3 Earth radii away. The mean diameter of the Earth is 12,742 km which gives a radius of 6,371 km so the distance to the Moon is 62.3 * 6,371 = 396,913 km or 246,755 miles. You can use the source to get the distance for some other time. After entering the date and time (UT is GMT which is the time in London, England), see the table at the bottom for the distance.

It's new moon.... actually right now it's only 1% full. Wait till tomorrow and the day after tomorrow, beautiful sight, a thin sliver... gorgeous. Enjoy!

The Moon rotates on it's axis and revolves around the Earth in 27 1/3 days. The time from one full moon to the next is 29 1/2 days. The reason they are not the same is that during the 27 1/3 days that it take the Moon to go around the Earth, the Earth has moved relative to the Sun, and it takes another 2 days or so before the Moon is directly on the other side of the Sun (which is what gives a full moon). It is similar to the reason why the Earth rotates on its axis once every 23 hours 56 minutes and 4.1 seconds, but its 24 hours from noon to noon.

Yes, the Moon does rotate around it's own axis.\n\nHowever, the reason we always see the same side of it is the fact that the Moon rotates about as fast as it makes one full lap around the Earth.  It takes about 27 days.  So, the Moon doesn't rotate as fast as Earth does(27 days compared to one day).

There are 2 astronomical cycles involved here.\n\nThere's a 19 year cycle, where moon, sun-earth are in same relative positions all year long.\nThere exists an eclipse cycle here but not like the saros cycle, below.\n\nThe other is the "saros" cycle, (the eclipse cycle), which is 18 years, 11 days 12 hours, 3 and 1/3 seconds.\n\nThese are astronomical absolutes--you can depend on them.\n\nI can't decipher your dates above, but after 62 years as an amateur astronomer, I can assure you that my figures above are correct...\n\nI appreciate your interest in these cycles--you are one in about 10,000, (maybe in 100,000) that can even pose such a question.

You could ask the same about the sun (although the angle of Earth's rotational axis makes things somewhat more complicated in the polar regions). The moon is simply so far from earth that your position on earth's surface becomes secondary. Half a day the earth's rotation will bring you onto the side where the moon is, half a day it will bring you onto the opposite side.\n\nI know from personal experience that the moon remains visible and fairly high on the horizon even beyond the arctic circle when the sun won't rise above the horizon any more. Apparently earth's rotational axis is (almost?) perpendicular to the plane in which earth and moon circle one another.

Do you have a calender? Most of them show the dates of First Quarter, Full Moon, Last Quarter, and New Moon within a day of their ocurrance. The discrepancy may be due to time-zone difference and what geographical area they are using (local or GMT or something else). There are various websites that list it too.\n\nOccasionally, a calender will erroneously list the moon's phases opposite what they actually are. I have a daily cat cartoon page calender which has this particular error. Thus it will list the moon's phase as New when clearly it is full looking up at the night sky. But generally most calenders don't have such blatent errors. \n\nThis question is asked over and over again. Rather than directly answer your question, I have hopefully pointed the way for you to get the answer yourself instantly anytime.
