Why is the crater tycho brahe always facing earth?
The Tycho crater on the Moon appears to always be facing Earth due to a phenomenon called "libration." Libration is the slight rocking and wobbling of the Moon that allows us to see a slightly different angle of the Moon's surface over time, making it seem like the Tycho crater is always facing us.
The moon has three kinds of motion or movement what are those three movements?
The three kinds of motion of the moon are rotation on its axis, revolution around the Earth, and libration (a slight wobbling movement). Rotation on its axis causes the moon to experience day and night, revolution around the Earth gives us the phases of the moon, and libration allows us to see slightly more than 50% of the moon's surface over time.
How much does the moon wobble up and down?
The apparent wobbling by the Moon is called "libration"; you can find more information, for example, in the Wikipedia article on "Libration". The Moon doesn't really wobble; rather, from Earth we sometimes see different parts of the Moon, because (a) sometimes we see it more from the north, sometimes more from the south (since the Moon's axis is not exactly perpendicular to its orbit around Earth), and (b) since the Moon's orbit isn't exactly circular, but it rotates at a constant angular speed, as a result we sometimes see a bit more of the Moon's east side, and sometimes more of its western side. In total, we can see about 59% of the Moon's surface from Earth (at different times).
Which observed motions of the moon are real and which are apparent?
This is very interesting. It could be argued that we really don't observe any of the moon's true motion. We don't observe the moon's axial rotation, even though we know that it happens. The swaying of the moon by libration is an apparent motion and not a true motion. This libration has to do with things like the moon's elliptical orbit around the earth, and the fact that its rotational velocity is just about constant. There is another libration that is related to the eccentricities of the moon's orbit relative to the earth's. The moon appears to rise in the east and set in the west, as does the sun, but this orbital motion is apparent and not true. The moon is orbiting the earth in the other direction. It appears to rise in the east and set in the west only because of the earth's very fast axial rotation. The earth rotates once each day, and the moon orbits the earth once in a lunar cycle. This means that the moon's true orbital motion around the earth can be seen only indirectly.
Why does the moon sometimes look like it's on its side?
The phenomenon you're referring to is known as "lunar libration," which is caused by slight wobbling and an elliptical orbit of the moon. This allows us to see slightly more than just one side of the moon from Earth, leading to the appearance of the moon tilting or rocking back and forth.
What is the medieval unit of weight?
libration
Is the Moon's orbital wobble changing from east west to north south and what will the effect be on Earth with Mars moving closer to the moon and is it pushing the moon closer to Earth?
The moon doesn't wobble, if you refer to the movement commonly called 'libration'. That is an apparent motion only, and not a true motion of the moon. There is both east/west libration and north/south libration, and they are independent of one another. Mars is not pushing the moon closer to earth. On average, the moon is very slowly moving farther and farther from the earth, not closer.
What fraction of the moon is never seen from earth?
Due to the libration of the moon we see approximately 60%, so there is about 40% we do not see from the earth.
On red faction guerrilla why wont the liberation mission in the eos sector unlock?
if you didnt buy the nano forge you cant do the libration and its not over u will see
What happened to hilter ant the jews after the libration?
Hitler would go on to kill himself and the Jews would be re-patriated or would seek a new life where they chose.

How much of the moon do you see from earth at any time?
This depends on where the moon is in its orbit and its position in relation to the sun and the observer and the time of the observation.Theoretically you can see just over half of the moons surface over a period of time due to libration.
What is the thing that looks like a stretched out 8 on a globe called?
It is called the analemma. It describes the apparent change in position of the sun that results from the tilt in earth's axis, and the libration caused by earth's changing velocity in its orbit around the sun.
Do we always see the same side of the Moon facing us?
Yes, but not exactly. There are slight variations in angle caused by "libration" that cause the moon to appear to wobble back and forth and up and down during the course of any given month. So in reality we are able to see slightly more than 50% of the moon's surface (but, of course, we can see only 50% of it during any given full moon). We would have to observe the moon over a period of roughly 15 years in order to "see" every part exposed by this libration process.
What do you mean by the dark side of the moon?
That refers to the side that can't be seen from Earth. The Moon has a bound rotation, meaning that we always see the the same side (more or less; but read about "libration" for more details). The "dark side of the Moon" is not really darker than the other side; it simply refers to the fact that we can't see it from Earth.That refers to the side that can't be seen from Earth.

Why can you see more than one half of the moon from earth?
The effect is called "libration". In fact there are several such effects. Sometimes we see more of the northern hemisphere, sometimes more of the southern, since the Moon's axis is not exactly perpendicular to the plane of its orbit. Also, since the Moon rotates at a constant angular speed but moves around the Earth in an ellipse - and therefore doesn't advance the same number of degrees in its orbit every day - we sometimes get to see a bit more of its eastern side, and at other times, more of its western side. In fact this is the most important of the libration effects.
