Oh, Bezzellzebub is just teasing with all of you; his superior vegetable-fueled intelligence KNOWS the moon travels in an elliptical orbit around the
earth, actually bypassing the earth's shadow (except during lunar and solar eclipses, see later....) and the moon doesn't rotate on its' own axis, but
as it travels around us displays only ONE SIDE to the sun.... WOW... he said...
So, as the moon comes from in front of us we see the first quarter and half, and as it travels behind us we see a full moon; the course of the moon is
elliptical with an apogee and a perigee, which makes it closer and farther away also, which makes the moon bigger and smaller... but I digress. Moon
behind us, FULL MOON. Moon in front of us, NEW MOON (no moon, between sun and us) not only no light on moon, but IT'S FREAKING DAYLIGHT, and you'd
need optics to see the moon, but it's right there all the time.
NOW: When that elliptical orbit lines up once in a while (those gall-darned scientists can predict it to the second for hunnerts of thousanth's of
days behind and in frunt of us, the bastids) and the sun, moon and earth just HAPPEN to hit a shadow line, BINGO! - - - Eclipse. Or partial. A lotta
virgins went down during those, prolly like Bezzelzebub. Maybe a few 4x4'ers too, but I doubt many carnivors; we're still here.
Any logical questions?

nope - the moon rotates around it's own axis once in 29 days. And the entire surface of the moon is illuminated once during one 29 day cycle on it's
rotation around the sun, however, it displays only one side to earth

Erm, I believe the earth's gravitational pull holds the moon into a non-axial orbit; it doesn't rotate, but faces us constantly due to our close
proximity and gravitational pull. The moon's 'rotation' is due to our gravity, not its' own rotation. I displace your theorems and replace them with
one of my own... HAHAHAHAHA! (mythbusters) JUST KIDDING; WHO G / A / F ??

Ah it`s just all positions. Look now. The moon is a sliver, the sun has just set. If you go WAY out in outer space, you will see a full moon. There is
always a full moon somewhere out there, even if it`s Mark or Jeff dropping their pants!!!
BUT the real deal is coming fast. That would be the moon getting between the earth and sun. This will happen August in 2017. Going clear across the
USA. The most watched solar eclipse EVER!!!!
Make your plans now, and don`t settle for 99%. It HAS to be 100% to see the Corona Beer!!!!
Seriously I can`t give the science answer but could give a sitting around the campfire answer by pointing here and there.
Remember on the full moon, the sun sets as the moon rises. And solar eclipses only will happen on a new moon.

IF the moon rotated on its own axis every 29 days, and facing the earth at a constant; my pea-brain sez "THAT DOES NOT COMPUTE". If for a fact the
moon faces us constantly, AND rotates, wouldn't we see other sides of it? Sounds to me like the poor ol' rock is locked to us like Palin to Alaska
(no offense, northern neighbors). We'll see the same smilin' face telling us fables for eternity. So how is it rotating on its' axis??? It ROTATES
THE EARTH APROXIMATELY 29 DAYS mas o meno. It's all kinda like old age; one day you wake up and say, '' AW, SHUCKS, GRAVITY WORKS!".
To your original question; due to the elliptical orbit of the moon around the earth, there's always a slight penumbra of the earth's shadow on the
moon. You don't always see 100%; just some people have to quibble. Did I win yet, or are you still gonna play professor?

Super picture ... simply outstanding ... thanks much
lunar libration
"It’s common knowledge that our moon has a nearside and a farside. One half of the moon always faces Earth, and one half always points away. Does this
mean we can only see 50% of the moon’s surface from Earth? No. In fact, over time, it’s possible to see as much as 59% of the moon’s surface, due to a
slight north-south rocking and east-west wobbling of the moon known as lunar libration. Follow the links below to learn more:"
http://earthsky.org/space/how-much-of-the-moon-can-we-see-fr...
Knew we could see 50% ... had to look up the other
Thanks again ... for a great question and such a great picture

Definition of libration~
1: an oscillation in the apparent aspect of a secondary body (as a planet or a satellite) as seen from the primary object around which it revolves.
wow.
A whole NINE PERCENT. Now, that's impressive. Oscillating, which means there's probably a nine-percent loss from the original 50% as well, which
either means we see 4.5% of BOTH sides, or 9% of either side, which would mean we'd be seeing 72% OF THE TOTAL MOON'S SURFACE!!!! OK, which is it?
Whew, glad we got that all cleared out for the night-time scholars out there.
And all this time I thought 'librations' was a form of liquid entertainment, or oscillatory entertainments of the 'toy' variety, found in many
Ensenada motels.
Man, I love this Chit! What else can you entertain yourself with after late-nite TV??????????

so, both earth and the moon are rotating around the sun
earth's pattern is pretty simple
but the moon's path is cool:

Moon rotates in (serendipitous or causal) synchronistic orbit with earth. Seeing only half or quarter or whatever phase is just the relative
positioning with our viewpoint. Half of the Moon is always lit, just like Earth.

The "dark side of the moon" is also a misnomer as it gets as much sunlight each month as the side which always faces the earth.

Trying to understand the question. Could another way to ask it be: "Why is the moon not always full?"
In that pre-Google Earth and social media epoch, The Code was adhered to. It was based on a simple verity: if a locale had been transformational for
you, and you had put the hard yards in to get there and to learn it, to know it, why in god�s name would you broadcast the news, thus ruining the
future experience not only for yourself, but for future adventurers?
