Questions about the moon
Hello,
reading a post earlier today someone mentioned that the other side of the moon will be visible to us in a week or so, is this true? Will we see it in north america and can you really see the american flag on the moon, if so where is it located? I would really apreciate it if someone could enlighten me on the above questions. Thanks |

You must have mighty long legs after having them pulled so much. None of what you inquire about is true or possible. |

: Hello, reading a post earlier today someone mentioned that the other side of the moon will be visible to us in a week or so, is this true? You can see small bits of the far side every month. Look up "lunar libration". Will we see it in north america and can you really see the american flag on the moon, if so where is it located? There are several. You would have to go to the moon to see them. I would really apreciate it if someone could enlighten me on the above questions. Thanks |

No. The farside of the moon is never visible from earth (the moon always keeps one face toward this planet). Will we see it in north america and can you really see the american flag on the moon, if so where is it located? No...the flag will still be 240,000 miles away. R |

Thanks http://www.space.com/spacewatch/myst...ay_030908.html For the record, the Moon always shows the same face to Earth, whether we can see it or not. This is because in the exact time it takes the satellite to orbit around the Earth once -- the 29.5 days -- it also revolves one time on its axis |

This means that you get an effect called libration which allows you to see a bit of the far side. See: http://www.theman.themoon.co.uk/librations/ Llanzlan. |

Will we see it in north america and can you really see the american flag on the moon, if so where is it located? I would really apreciate it if someone could enlighten me on the above questions. Thanks I think what you might have heard was that a small part of the far side will be visible due to a phenomenon called libration. While the moon generally keeps the same side facing earth we can often see a bit beyond the limb because the moon has a slight "wobble" that tips various portions of is limb towards us during its revolution around the earth. This allows us to see 9% of the "far side" (ie 59% rather than 50% of its surface). It so happens that in the last week of this month when the moon is between last quarter and new moon the (celestial) eastern edge of the moon will have a strong tilt (9 degrees) and will show a feature on the far side called Mare Orientale that is normsally out of view. However you will need a telescope to this feature. But you can actually track libration with the naked eye. Just what the naked-eye circular feature called Mare Crisium near the (celestial) western edge of the moon. You will observe that during a lunar cycle as the moon librates M.Crisium wanders slightly in and away from the edge of the moon. The flags on the moon are not visible even with the world's larges telescopes. Martin Lewicki |

Why doesn't our moon revolve? Is this characteristic of most moons? It does rotate, only its period of rotation is equal to its period of revolution around the Earth. This is not coincidence; the Moon has become tidally locked to the Earth as tidal forces and friction worked on it. Most small moons in the solar system are also tidally locked to their primary. |
