A satellite orbitting the earth would go through phases mucg like the moon. It is day and night. The side away from the sun would be dark while the side towards the sun would be light. Our visual observations are incapable of noticing this as even the ISS is very small to the naked eye. It is likely possible to record small changes using a telescope but that's really a waste of resources.
Assuming the question really is "Who took the first picture of the entire Great Wall of China" I do not see how this is possible, given the length of the wall. It would be possible to take a picture of the entire Great Wall from a low-orbiting satelite or space shuttle, except portions of the wall no longer exist, so it would not be the "complete" wall.

Anti hydrogen , antimetter.
the Asteroid belt has no satelites all the asteroids that make up the belt is another asteroids satelite so there would be thousands of satelites
The mass of the earth is over 80 times the mass of the moon. A massive object will tend to capture less massive objects in its gravitational field.____________But consider this: if the moon happened to be the same general size and mass as earth, which would orbit which? You would observe them each orbiting around an invisible spot half way between them, their 'system' center of gravity otherwise called the 'barycenter'. They would effectively be orbiting around each other. As the moon becomes less massive, what determines the 'cut-off' between orbiting around each other and the smaller orbiting the larger? In fact it is still true that earth and moon are each orbiting their barycenter. Interestingly, the barycenter in this case is within the body of the earth, because the earth is so much more massive than the earth.
Yes.
yes but it isn't that long distance because the satelite's for the phone companies are orbiting the earth
A continuous acceleration toward the center of the Earth equal to GM/R2 where G is the Gravitational Constant, M the mass of the Earth and R the distance between the satelite and the center of the Earth. If you multiply this by the mass of the sattelite itself, you get the force acting on the satelite to produce the acceleration. It is this force, causing this acceleration, which holds the satelite in orbit. Without it the satelite would obey Newton's first law of motion and just move out in a straight line. Note that this is true of any object orbiting any thing, whether it is an artificial satellite orbiting the earth, a planet or spacecraft orbiting the Sun, or a star orbiting the center of the galaxy.
Because of the inverse square law of gravity, an object close to the Earth's surface feels a greater pull than an object further away. This would mean an artificial satelite in an orbit near Earth would have to travel faster to remain in orbit. One further away would travel slower. Close to the earth, a satelite might complete an orbit in, for example, 90 minutes; but the earth rotates once on its axis in 24 hours. This would mean the satelite would always have to travel faster than the Earth spins. Too far away, and the satelite would take longer than a day to orbit the Earth - so the planet would spin faster than the satelite's orbit. For a geostationary satelite, it would need to be at just the right distance, in an orbit that keeps it at the same place as seen from the rotating Earth - orbiting as fast as the Earth is spinning. Geostationary satelites get parked a little over 22,200 miles above the Earth's surface and in orbits the same direction as the Earth spins - and are thus useful for communication and weather functions.
To see all the phases of Venus is impossible in the Earth-centred model of the Solar System. The case of the Moon is different. Simple geometry shows how you can see all the phases if it revolves around the Earth. If the Moon's phases were caused by it orbiting the Sun, then the Moon would have to be millions of miles from Earth. We know the distance to the Moon very accurately and it's obviously orbiting the Earth. But, of course, the Moon does go round the Sun too, along with Earth, during the year. I hope that's clear.
No, if the moon did not rotate as it orbits the Earth, we would always see the same face of the moon and there would be no changing lunar phases. This is because the changing phases of the moon are caused by the angle between the sun, Earth, and moon as the moon orbits Earth.

The Earth would be all the time in the same direction - more or less. It would have about 4 times the apparent diameter the Moon seems to us - about 2 degrees instead of 1/2 degree. You would see the Earth pass through all the phases, similar to the Moon's phases.The Earth would be all the time in the same direction - more or less.

During the Moon's revolution, an observer in space would see the moon, but would not be able to see it spin around. From far to the north, about the solar system, the moon would appear to make a squiggly

Nicholas Copernicus is believed to be the first to propose the heliocentric model of the solar system, as it is called. However, the real proof was observed by Galileo Galilei. Using the telescope he greatly improved, he observed that Venus goes through all of the phases, just like the moon. If Venus and the sun were orbiting Earth, that would be impossible.
Sand would lay on the bottom, water would occupy the middle, and oil would float on the top. So, in a tall tube of all three substances, careful extraction from three heights of the tube would separate as required.
