To a close approximation, none of them are visible to the unaided eye. With our bare eyes, we can see only
a few thousand of the brightest ones. That's something like 0.0000025 percent
of the stars in our own galaxy, and no individual stars in any other galaxy.
The observer of a solar eclipse would typically be located on Earth, witnessing the event as the moon passes between the sun and Earth, causing either a partial or total eclipse. The specific location on Earth where the observer would be situated would depend on where the eclipse is visible from.
Both lunar and solar eclipses are the result of positioning 3 astronomical bodies (earth, sun and moon) in a straight line relative to the observer. A solar eclipse is observed when the sun, moon, and earth are positioned in a straight line with an observer on the earth. A lunar eclipse is observed when the sun, earth, and moon are in a straight line with an observer on the earth. A lunar eclipse, as observed by an observer on the earth would appear as a solar eclipse as observed by an observer on the moon.
The smallest size of a cell that can be seen with the unaided human eye is about 100 microns, which is roughly the size of a grain of sand. Anything smaller than that would generally require a microscope to be visible.
That person in London would see a new moon.
No, an observer from Earth would not see all the planets rotate backward at the same time. This is because each planet rotates on its own axis and orbits the sun independently, so their motions appear to be unique relative to Earth's position.
Very nearly all of them are not visible to the unaided eye. With our bare eyes, we can only see the brightest few thousand stars ... something like 0.0000025 percent of the stars in our own galaxy, and no individual stars in any other galaxy.

That would have to be a high mountain peak in the distance I would think.
Full, large or whole. Maybe the question was meant to be...How would the Earth appear to an observer on the moon during a full moon?
The moon does not change (much). What an observer on Earth sees changes as the Moon orbits the Earth and the Earth/Moon system orbits the Sun much more slowly is the illuminated portion of the moon growing (covering more and more of the visible portion of the Moon) and when the Moon is full, the Sun Earth and Moon are more or less in line (if they were exactly in line it would be a lunar eclipse - which does happen a few times each year). Then as the Moon continues to rotate around the Earth, night after night, less and less of the illuminated portion is visible to the observer on Earth.
it would still appear to rotate
An observer would experience the greatest force due to Earth's gravity at its surface, which is closest to the center of the Earth and where the gravitational acceleration is strongest.
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

Everybody on Earth who can see the moon at any particular moment sees the same phase. The distance across the Earth, is not far, compared to the distance to the moon, for there to be any perceivable change in perspective.
Exactly due north of him, and on the horizon.
