Given a photo of the Moon, taken from Earth, is it possible to calculate the position of the photographer's site? @DanNeely I think they rely more on the landscape than on the moon in order to locate the shooting point. |

Given a photo of the Moon, taken from Earth, is it possible to calculate the position of the photographer's site? interesting... But I think that, in order to determine the location, they rely more on the landscape than on the moon... |

The square in the Newton's law of universal gravitation is really a square? Asaph Hall III (1829,1907) or Asaph Hall IV (1859–1930)? |

The square in the Newton's law of universal gravitation is really a square? @Manishearth :-) It was 1990s and maybe the professor did not mention the year of the researches... I remember it was just an aside comment. |

Given a photo of the Moon, taken from Earth, is it possible to calculate the position of the photographer's site? @dagorym Thank you very much for your complete answer. Assuming I can ignore the libration, and considering a simple model like the one in the diagram I added to the question (SL is the sublunar point, right?), is it possible to estimate the error in the determination of the photographer position? I would like to know whether I can say "the photographer was in the northern hemisphere" or "in Europe" or "in Italy". From the law of sines I think I can write R*sin(alpha+beta)=D*sin(alpha) but then how can I find how an uncertainty in alpha (measured in the photo) propagates to beta? |
