# The far side of the moon

While spacecraft have sent back images of the far side of the Moon, until that was possible we could only see one side of it. Wayne Schlingman explains why that was.

Now the Moon takes one trip around the Earth in the same amount of time it takes to make one rotation around its own axis: about 28 days. From Earth, we always see the same face of the Moon; from the Moon, the Earth stands still in the sky.

All sides of the moon experience night and day just like we do here on Earth. All sides have equal amounts of day and night over the course of a single month. A lunar day lasts about two Earth weeks.

Here is a short video.

I wonder if the flat Earthers think that the Moon is flat too. You would think that the fact that we see only one side of the Moon would make a stronger case for the flatness of the Moon than the case they have for the flatness of the Earth.

Errr--isn’t a lunar day closer to four weeks? It takes roughly 28 days for the moon to circle the Earth, 13 times a year. Since the Moon is tidally locked to the Earth, showing only the one face, that would make 28 Earth days per Lunar day (roughly).

Mobius:

Yes, that quote was a bit confusing. It’s referring to the length of daylight periods, which is about two weeks. That’s not the length of a day, which includes both “daytime” and “nighttime,” or however you’d like to put it.

The moon is simply a large disc pasted on the dome over the flat earth. So, I suppose technically it is flat.

Really? And it still didn’t occur to you to consult Flat Earth Society? It took me less than five seconds.

“The moon is a sphere. It has a diameter of 32 miles and is located approximately 3000 miles above the surface of the earth.”
