The moon is Earth's only natural satellite. The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith). The moon has no atmosphere. Recent lunar missions indicate that there might be some frozen ice at the poles.
The same side of the moon always faces the Earth. The far side of the moon was first observed by humans in 1959 when the unmanned Soviet Luna 3 mission orbited the moon and photographed it. Neil Armstrong and Buzz Aldrin (on NASA's Apollo 11 mission, which also included Michael Collins) were the first people to walk on the moon, on July 20, 1969.
If you were standing on the moon, the sky would always appear dark, even during the daytime. Also, from any spot on the moon (except on the far side of the moon where you cannot see the Earth), the Earth would always be in the same place in the sky; the phase of the Earth changes and the Earth rotates, displaying various continents.
THE MOON'S ORBIT
The moon is about 238,900 miles (384,000 km) from Earth on average. At its closest approach (the lunar perigee) the moon is 221,460 miles (356,410 km) from the Earth. At its farthest approach (its apogee) the moon is 252,700 miles (406,700 km) from the Earth.
The moon revolves around the Earth in about one month (27 days 8 hours). It rotates around its own axis in the same amount of time. The same side of the moon always faces the Earth; it is in a synchronous rotation with the Earth.
The Moon's orbit is expanding over time as it slows down (the Earth is also slowing down as it loses energy). For example, a billion years ago, the Moon was much closer to the Earth (roughly 200,000 kilometers) and took only 20 days to orbit the Earth. Also, one Earth 'day' was about 18 hours long (instead of our 24 hour day). The tides on Earth were also much stronger since the moon was closer to the Earth

I'm not really sure what it is about the moon you're writing about, but some interesting facts are:
-constantly bombarded by asteroids and other material in the solar system
-We only ever see one side of the moon becuase it rotates around it's own axis every28 days, which is how long it takes to orbit the earth, so we always see the same side of the moon.
-some scientists think the moon is made up of material that was kicked off the earth when earth was hit by a massive comet, because unlike most planets/moons in the solar system that have a solid core, the moon seems to be relatively constant in its density.

Your paragraph is somewhat descriptive! It somewhat paints a image on your suggestions- "The partitions have been tinted a very easy lavender. there replace right into a huge window with white silk curtains that took up just about the full wall, excepting the gap below it the place a white sitting section handed off." It does use the apropriate language as of what i observed and it somewhat drew me in. additionally, make useful to no longer use the be conscious- ok. Use o.k. particularly. sturdy success and sturdy activity! :D
