Causes, Which at Different Times Make the Moon mountains Appear Altered

  • Johann Friedrich Julius Schmidt
Part of the Historical & Cultural Astronomy book series (HCA)


Apart from the optical changes which the lunar mountains undergo, in their position and shape, by the shortening on the spherical surface, but then by the effects of libration, there are others, which affect, to a much greater degree, the external appearance of individual mountains or entire landscapes, or appear to be completely temporarily transformed. This effect is due to the changing illumination of the mountains by the sun.
