Yeah, I noticed that... I was just elaboration on the issue that Star
pointed out... Whether it was a mistranslation or whether the person who
wrote the question was not that scientifically oriented, I don't know, but
at least in the translation, the technical term was incorrect... Since the
moon's rotational period is equal to its orbital period, it keeps one face
towards the Earth at all times... The sun on the other hand, has a
rotational period of around 25 days or so (less at the poles than at the
equator)...
If you presume the earth to be the axis, the moon rotates around the earth,
just like a tire, although bent a bit, rotates around its axis. The term
used isn't scientifically precise, but it works just fine in common usage.
