Does the moon rotate on its own axis, like the
earth, or do we see the same surface all the time?
The moon does rotate on it's axis, in the
sense that it makes one rotation for each
revolution around the Earth. So, we see
the same face of the Moon all of the time.
It would be interesting to ask an astronomer
how many of the moons in our solar system
do the same thing.
