moon's rotation

Do we always see the same side of the moon, or does it slowly rotate
in relation to our view?

To me, it seems quite a cooincidence that the moon rotates perfectly
such that we see the same side constantly.

It's not a coincidence. We see the same side because
the Moon's rotation is gravitationally locked to the
Earth.

The moon is tidally locked to the earth. It's not a coincidence.

It was painted that way from the beginning.

How about we moon you and find out?

No coincidence. In fact it's quite common.

It's called 1-to-1 spin-orbit resonance.

Question: What major solar system object is locked into a spin-orbit
resonance with its primary that is other than 1-to-1?

To me the coincidence is that I exist at a time to see so much wonder
in the skies. The tidal locked moon, the ability to go there, the fact
that the moon and sun show the same apparent size thus permitting a
solar eclipse. The fact that so much equipment is available and
obtainable to the average individual is truly amazing.

Just to add a bit more to what others have said. Although the moon is
tidally locked to the Earth, you can see a little bit of the far side due
to an effect called libration.

Greetings,
I understand the Moon is rotation locked by our much stronger gravity
to the Earth, but there is a slight variation on what we can see from
this side. But about 80 % of the supposed `dark side' (which isn't of
course) remains permanently out of view, at least from here. It's not a
co-incidence, just celestial mechanics.
Regards,
Ray.

answer neptune and pluto?

actually, you could include any asteroid or KBO at the respective
Langrange regions away from any planet, especially the ones at 2:3 and
2:5 resonances...

me? i've personally revoked pluto's license to be a planet...
