Right what I meant was, and let me clarify, that the Earth is orbiting but
not spinning simmular to the Earth spinning. Sure the Moon is spinning and it make one complete rotation with one complete orbit around the Earth. Like you said, at present, it is tidally locked to the rotation of the Earth. Locked being key, meaning that we can see only one face of the moon. It is not spinning in a way that we on Earth get to see it spin. It's a concept that I think some fail to grasp. "Roger Hamlett" wrote in message ... "Darrell" wrote in message ... What do you mean the "other's" spin. The moon is rotating, but isn't spinning. Both the Earth and the Moon are spinning. The Moon is (at present), tidally locked to the rotation of the Earth, so it spins 'in time' to the Earth, but it still spins. The same effect is working the other way, to a much lesser extent, and would eventually slow the Earth's rotation down, but not till long after the Solar system has died... Your comment is a bit like saying 'the top is rotating, but not spinning'. Rotation around an axis, _is_ a spin. Best Wishes "Roger Hamlett" wrote in message ... "Guy you lovetoHate The" wrote in message ... The Moon. No. The simple answer is, to remember that without friction, an object will spin forever unless there is something to influence it. The junk that came together to form the Solar system was all moving, and the spins this imparted onto the objects as they formed, has been retained, _except_ where something else influenced them. The collision that led to the formation of the Moon, will have changed the spin on the objects concerned, but the objects were spinning before this. Afterwards, the gravitational pull between the Earth and the Moon, have both influenced the other's spin, but didn't 'cause' it. In a sense, not spinning, would be the unusual case. Best Wishes |

Check out: http://www.msnbc.com/news/384600.asp See paragraph, "Orgin of
Spins" "G=EMC^2 Glazier" wrote in message ... This post fits in nicely because I'm thinking a lot about spin. I know Jupiter makes a complete turn in just under 10 hours.,and Venus takes 243 days to make a complete turn(spin). What are the best theories to account for such a fast and slow spin? Maybe if Venus spun faster it could cool down a little better at its equator?? I think I can use Photolysis here as I did on Mars With all that heat within Venus"s atmosphere that all the surface water evaporated high in the upper atmosphere,and this water vapor got hit by the ultraviolet radiation from the Sun and split the water molecules into hydrogen and oxygen. The hydrogen bleed off into space,and the oxygen combined with carbon to form carbon monoxide,and carbon dioxide. It must have volcanoes so sulfur dioxide,and iron oxide chemicals should make up a good percentage of its surface,that must be sandy Bert. |

It might be an interesting thinking of large objects like comets,and
meteors hitting the Earth at great speeds have effected the Earth's spin,,tilt and wobble. We have to keep in mind the Earth like all objects immersed in space has no weight. However it does have very great inertia. With this great inertia,and no weight this shows to people that don't understand inertia how to visualize it. Bert |

... Correction: ...the "MOON" is orbiting but not spinning simmular to the Earth.... Is your "MOON" something different than the Moon? The Moon spins on its axis once per orbit about the Earth. So in effect, its day is a month long. |
