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. RE |

We see the same side because the Moon's rotation is gravitationally locked to the Earth. |

We see the same side because the Moon's rotation is gravitationally locked to the Earth. 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. Clear skies and warm nights Dave Nagel |

To me, it seems quite a cooincidence that the moon rotates perfectly such that we see the same side constantly. RE 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. http://www.astronomy.net/articles/21/ Klazmon. |

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