I havent a clue what your are asking... are we talking about astronomy terms?  Elevation and declination?  Or are you asting about Lattitude and Longitude?

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.

This is a good question that made me think for a while.  First of all, you need to know how big Earth is.  Eratosthenes did that in ancient times by measuring the altitude of the sun at two different places on the Earth at the same time on the same day (presumably he had a friend helping him).  I've linked to a site detailing this measurement.\n\nOnce you know that, just wait for a lunar eclipse.  When the Earth is partially obstructing the moon, you will be able to see an arc of the Earth at the same time as an arc of the moon.  Then you can get a relative difference in curvatures between the Earth and the Moon (maybe by using coins of different sizes, for instance).  So once you know the ratio of the Moon's circumference to the Earth's circumference, just multiply by the Earth's cirumference to get the answer.

The distance to the sun can be computed by a variety of techniques.  Trigonometry and parallax measurements were used by ancient greek and arab astronomers to come up with pretty good estimates for the distances to the sun, moon, and other planets.\n\nThe sun's diameter at its equator is about 865,000 miles, and the mean distance from the earth to the sun is about 93 million miles.\n\nThe moon's diameter at its equator is about 2,160 miles, and the mean distance from the earth to the moon is about 238,900 miles.\n\nThe ratio of the diameters is 865000 / 2160 or about 400.  The ratio of distances is 93,000,000 / 238,900 or about 390.  So the sun is about 400 times larger than the moon, but it's also about 400 times farther away - so the sun and moon appear about the same size in the sky.\n\nThe moon's orbit around the earth isn't a circle, and the lunar distance varies from about 220,000 miles to about 252,000 miles.  When it is close to the earth, the moon appears slightly larger than the sun.  When it is in the further part of it's orbit, the moon appears slightly smaller than the sun.  If an eclipse occurs when the moon is furthest from earth, the moon's disk can't completely cover the sun.  The result is an "annular" eclipse.\n\nIncidentally, the moon gets slightly farther away from the earth every year.  Eventually, in the distant future, it will be too far away to produce a total eclipse of the sun.

The average distance between Earth and Moon is approximately 30 times Earth's diameter.

GREAT QUESTION!\n\nThe answer is: In several ways.  First of all:\n\n1. Earth rocks!\n\nInstead of following a smooth Keplerian orbit around the Sun, Earth's own centroid performs an oscillatory motion about this "mean path."  By careful observations of the nearest PLANETS (but not the Moon --- why not?!) the amplitude of this Moon-induced "rocking" can be measured: Earth's centroid wobbles back and forth by about 3/4 of the Earth's own radius.  From this alone, one can deduce that the Moon's mass is ~ 1/80th that of the Earth.  \n\n[How?: From cunning arguments, the Greeks worked out long ago that the Moon was about 60 Earth radii distant; but when things are orbiting around one another with an equal but opposite force attracting them, it's the centroid of the COMBINED system that stays fixed, and the sizes of the "orbits" of both objects about their common centroid are inversely proportional to their masses --- just as though there's a giant Archimedes lever out there in space!  So that's how the "60" and the "3/4" combine to tell you that M_moon ~ M_earth/80.]  \n\nFurthermore, THAT is how it was already known in Victorian times that the gravitational acceleration at the Moon's surface must be ~1/6th that of our familiar 'g' at the Earth's surface.  \n\n[The ACTUAL PHYSICAL distance to the Moon is also needed to work this out, so that one can obtain its physical from its angular size.  You then plug the Moon's mass and physical size into Newton's Law of Gravity, applied at the Moon's surface.  Since the Greeks knew the Moon was ~60 Earth radii away, that actually meant measuring the Earth's size well!  \n\nWhen Newton made his own first "Moon check" on his law of gravity, it didn't seem to fit.  He was away home from Cambridge, in Lincolnshire, avoiding the Great Plague of 1666, and thus away from up-to-date books and other information.  But some time later, perhaps on returning to Cambridge, he learned of a new measurement of the Earth's size.  He then went back to his Moon test again, and found that when he'd corrected his earlier calculation, "it answered pretty nearly."  \n\nThat's how he first confirmed his Law of Gravity.  It tells you something about perseverance.]\n\nSo in the end, things like the acceleration at the Moon's surface were already known long before an astronaut demonstrated the "strength" of it by dropping objects on the surface of the Moon, on live television. \n\n2. The tides.\n\nAnother effect of the Moon's gravity on the Earth is of course the tides, though this is a more subtle and less direct (scientific) effect, as it's then the DIFFERENTIAL TIDAL FORCES (derived --- chuckle --- from differentiating the Moon's gravitational force at different places all over the Earth/Oceans etc.) that provide the forcing effect.  However, as we are riding on the surface of the Earth itself, we can ourselves more directly experience and observe this more subtle effect, through the tides, than we can the "rocking" produced by the stronger, main part of the attraction.\n\nI hope you get to study this some day; it's fascinating stuff!\n\n[Here's a funny thing that has always intrigued students at Starfleet Academy.  As viewed in a frame of reference in which the Sun is at rest --- the frame you use when you want to show the planets orbiting the Sun --- what do you think the path of the Moon looks like in space?  Does it spiral a lot, in overlapping circuits, around the Earth's path, or does it slowly and majestically make a gradually curving sinusoidal like motion, first curving in, then curving out (relative to the solar direction) about the essentially circular path of the Earth?  Would you believe that it always CURVES IN TOWARDS THE SUN?!!\n\nIf you know about gravity, acceleration, and the two separate orbital velocites

In reality, the Sun is always the same size! The illusion of difference in what appears to be a difference in size can be explained by, where on the planet you are viewing it from(are you viewing the rising and the setting sun in the East? The west is farther away when you watch it set), the Seasons(distance from the Earth), the angle at which you are viewing it from, atmospheric inconsistancies and plain old Optical illusions. Take your pick or combination of the above.

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.

The preceding first, third, and fourth answers are correct. Additionally, you should multiply the units, and remember that  (1 kg) × (1 m/s²) ≡ 1 N. Then…\n\nOn the moon, 80 kg × 1.62 m/s² = 129.6 N and \non the earth,  80 kg × 9.80 m/s² = 784 N. \n\nAnd check your spelling of "weigh."

1- yup, Earth\n2 - The sun is about 400 times the diameter of the moon, but is also about 400 times farther away\n3 - Cosmic rays ( a form of electromagnetic energy that would sterilize the surface of our planet within a few months if not blocked ), and meteors, thousands of which would hit us every hour.

The moon gets its light from the sun!  Way out in outer space, the sun produces light and heat.  The sun's energy is reflected off the surface of the moon and bounced back to the Earth.  What we see is the reflection of the sun's light on the moon.

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.

The sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass.\n\nIt would take 109 earths to stretch across the sun, and it would take over one million earths to "fill up" the sun if it were hollow.\n\nIf you think of the sun as being the size of a basketball, then the earth would be about the size of the head of a pin.\n\nThe diameter of the Sun is 865,400 mi \nEarth equatorial diameter=7926 mi (12760 km)\nEarth polar diameter=7900 mi (12720 km)\n\nSun's surface area is approximately 12,000 times that of Earth.\n\nMore info:

About  93 million miles depending on where we are in the orbit as the orbit is not circular. The sun is made of gas, and actually more of a plasma. The earth has a solid iron, nickel core with a molten iron nickel outer core and then then mantel then the crust with rock on it.
