As a matter of fact, I have 3 degrees in aeronautics and astronautics, and I know more about a spinning ball (the Earth) than you do. If you are going to come on like this, it is painfully obvious you don't know squat and are not prepared to prove anything with a calculation. And by the way, go to the southern hemisphere and see the stars you can't see from the northern hemisphere. Your problem is that you only believe stupidity on paper and refuse to look out the window, or travel around the world.
The moon and the earth both have the same light source right? The earth spinning the moon is not right? The tiny moon is caught in earth orbit right?
How does the tiny object flying rapidly around the rapidly spinning earth LIGHT PATTERN CHANGE VERY SLOWLY while the light pattern on earth is moving constantly?????
Take your time. Do experiments and computer models of you must.
Same light source. Both are rotating (the Moon's "day" is 30 days long). The Moon is in orbit around the Earth. So far, you are confused.
The Moon is not a "tiny" object; it is about 27% of the diameter of the Earth. The Moon takes 30 days to orbit the Earth, and we see it at different angles, relative to a fixed direction to the Sun. (The Earth takes 1 day to rotate under the Sun.) The lunar illumination angle varies at a rate of 360 degrees / 30 days = 12 degrees per day. This is well known and is easy to see demonstrated with an orrery.
Just to be clear, the Moon is not illuminated by sunlight reflected from the Earth; it is illuminated by the Sun. There is some light reflected from the Earth (Earthshine) and this can be seen as a faint illumination of the dark face of the Moon when the Moon is closer to the Sun than the Earth is. When the Moon is visible in the daytime sky, one can sometimes see a complete disk, where the part not illuminated by the Sun is lighter than the sky background (but not by much). (If there were no Earthshine, the dark portion of the Moon's image would be filled in by skyshine and there would be no visible edge.)
Is there a question about any of this? A grade-schooler would be familiar with this picture.
Put yourself on that spinning ball. My count I should have about ten nights with no moon.
How far away is the nearest star? How fast is it orbiting earth? Well it must be orbiting earth if you can see it on that merry go round.
The moon is about 1/4 of 1% the distance of the sun. According to your books. With a very coincidental relative size in the sky. But it maintains that light pattern and keeps up with our spin so we can observe it. With a field of conspiring stars. Each at their extreme distance synchronized with our "spin" .
When the cosmos is rotating at a speed based on Earth's "spin"... I'm sorry that means the earth isn't, and the stars are.
Actually, we should have about 15 nights with no Moon, so you really don't understand what it means for the Moon to orbit the Earth. But, in compensation, we have 15 days with a Moon.
The semi-major axis of the Moon's orbit around the Earth is about 384,400 km (it is an elliptical orbit). The semi-major axis of the Earth's orbit around the Sun is about 149,598,000 km (or 93 million miles). So, yes, it is about 0.257% of the Sun's distance.
The Moon is not synchronized with our "spin" (daily rotation). It's own day is synchronized with its orbital period, which is why it constantly faced toward us. Neither are the stars synchronized with our "spin," though their reference position relative to local midnight moves 360 degrees / 365 days = 0.986 degree per day. They are not moving; we are. Their apparent rotation through the day is 360 degrees / 24 hours = 15 degrees / hour. You have to understand that, for us, the stars are "fixed." The cosmos is not rotating at all. The stars' actual movements are so small, they can't be detected unless a century or so has passed.

Glad we got all the fallacy and appeals to useless authority and expertise out of the way.
