Does the distance between the moon and the sun appear the same from anywhere on the earth?
104556
No.\n\nThe distance between the Moon and the Sun is always changing.  Sometimes the Moon is between the Earth & the Sun, and sometimes it is on the other side of the Earth from the Sun.\n\nAll because the Moon is orbiting the Earth.

On perigee, the moon is closest to the earth. On apogee, it is its farthest from earth. This happens every month, so don't worry if you missed it. I found a good site you can go to:

Mean Distance of Moon from Earth - 238,712 mi (384,400 km)\nGreatest Distance of Moon from Earth (Apogee) - 252,586 mi (406,740 km) \nShortest Distance of Moon from Earth (Perigee) - 221,331 mi (356,410 km)

The moon's orbit is eliptical.  Sometimes it is closer and sometimes it is further from the Earth. Here are those distances:\n\nPerigee: 363,300 km \nAverage: 384,400 km \nApogee: 405,500 km

Because of their distance... The sun looks as big as the moon from our point of view because the sun, even though it is a LOT bigger than both the earth and moon, is very far from the earth, thats why it looks so small... just the same as you see a person approaching you from afar..

The Moon is Earth's only natural satellite. It has no formal name other than "The Moon", although in English it is occasionally called Luna (Latin for moon), or Selene (Greek for moon), to distinguish it from the generic "moon" (natural satellites of other planets are also called moons). Its symbol is a crescent. The terms lunar, selene/seleno-, and -cynthion (from the Lunar deities Selene and Cynthia) refer to the Moon (aposelene, selenocentric, pericynthion, etc.).\n\nThe average distance from the Moon to the Earth is 384,403 kilometers (238,857 miles). The Moon's diameter is 3,476 kilometres (2,160 mi). Reflected sunlight from the Moon's surface reaches Earth in 1.3 seconds (at the speed of light).\n\nThe first man-made object to land on the Moon was Luna 2 in 1959, the first photographs of the otherwise occluded far side of the Moon were made by Luna 3 in the same year, and the first people to land on the Moon came aboard Apollo 11 in 1969.

No.  But we see only the side that faces earth.\n\nHere's a good diagram that explains it better than I can...\n\n\nhttp://www.windows.ucar.edu/tour/link=/the_universe/uts/moon2.html

The average Earth-Moon distance is about 385,000 km.  Remember, the average is important because the moon rotates around the Earth in an eliptical fashion, which means that there are times when the moon is closer to the Earth than others depending on the point in its rotation.

No and Yes.\n\nThe moon is orbiting the Earth more slowly than the Earth is rotating.  It falls behind a little every day.  About 56 minutes behind.  So if tonight the Moon rises over the mountains at 8:00pm, tomorrow it will rise over the mountains at 8:56pm.  (thats the No)\n\nIn pretty much the same place. (There's your Yes)

Yes - the moon is far away, and the earth spins around it's own axis, creating day and night time. The moon would move a little 1/56 of phase shift during the half day it would take for the other half of earth to see the moon, but it's not noticeable.

We have the ability now to measure the orbit of the Earth, and all other planets, to very high precision, and it is not getting closer to the Sun.\n\nYou can do a very rough measurement yourself. If the Earth gets closer to the Sun, the Sun will appear bigger in the sky. Measure it in photographs taken by the same telescope a year apart. \n\nAnother consideration is this. Currently, the Moon and Sun appear the same size in the sky, which produces spectacular total eclipses of the Sun. If the Earth got just a little closer to the Sun, the Moon would no longer be able to completely cover the Sun. So if total solar eclipses continue as usual, that is evidence the Earth is not getting any nearer to the Sun.

I'm not sure about the distance to the moon, but I can explain the rest...\n\nLots of questions here... \n\nFirst, they found out about the curvature of the earth mainly by observing the earth's shadow on the moon during a lunar eclipse. You can easily see the Earth's shadow as curved and not straight.\n\nThe experiment with the sticks, performed by Eratosthenes, was to determine the circumference of the earth, and thus, how big it is.\n\nYou're absolutely right with the argument that the shade produced by a stick on a flat surface would be different than that on a curved surface.\n\nEratosthenes went with the [correct] assumption that the sun was so far away, that its light rays striking the earth would be parallel to each other.\n\nIn truth, this only occurs for an object that is infinitely far away, but the sun is SO far away, that this difference, from two different places on Earth, is negligable.\n\nSo if you have a flat surface, then no matter where you are on the surface, the shadow cast by a stick should be the same. If its noon, and the light rights are parallel, and the Earth is flat, then there should be no shadow no matter where you are on the surface.\n\nNow, Eratosthenes saw that at noon, in two different cities, that in one city, there was no shadow cast by the stick, meaning the sun was directly overhead, and at the same time in the other city, there was a small shadow, and measured the angle the stick made with the shadow. \n\nHe noticed the angle was about 7 degrees, which means its 1/50th of a full circle (360 degrees). Therefore, the two cities were 1/50th the way around the globe. Knowing how far the cities were, he multiplied their distance by 50 and got the distance around the globe. c = 2*pi*r, so he could then calculate the radius of the earth as well!\n\nThat's pretty much it, hoped you understood it. Its really amazing how they could get the size of the earth simply by using two old sticks and a little thought! :)

the moon doesnt circle the sun the moon circles the earth the earth circles the sun

It's about 93 million miles. It takes a sunbeam about eight minutes to reach earth once it leaves the sun. The moon, by contrast, is about 240,000 miles away, but I'm not positive about that exact number. I am positive about the sun, though.

On new moon day, the moon and sun are in the same direction from earth.\n\nThe non illuminated portion of the moon is turned toward us. In the bright background of light we are not able to see the moon.\n\nSince the earth rotates about its axis, this new moon is for all in the world.  \nThe sun and moon rises in the east and sets in the west almost with no time difference.\nTherefore the moon is in the sky during day time, even though we are not able to see it.\n\nIn each day, the moon separates from the sun approximately by 12 degree.\n\nAfter one or two days latter, the moon is separated from the sun towards east. Therefore, we see the moon (crescent moon) after sun set for few hours in the west or in the   evening. All persons in the world will view the crescent moon when it is evening for them.\n\nApproximately after seven days, the moon separates from the sun through 90 degree. \n When the sun comes to the zenith, the moon rises in the east. The moon appears as a half moon in the east. For the viewers it is a day time. We see the half moon from the afternoon of this day till mid night in the sky. At mid night it sets in the West. \n When the sun sets in the west the moon is seen in the zenith. All people in the world will see the half moon from mid day to mid night.\n\n\nAfter approximately fifteen days, the moon is separated from the sun through 180 degree. When the sun sets in the west moon rises in the west. We call this as full moon. Through out the night the full moon will be visible and during day time it will not be visible. This is the same for all people in the world. \n\nOne can complete this cycle from Full moon to new moon (in another 15 days).
