The Galilean Moons of Jupiter,he other planets from an unfavorable perch on our own moving planet, their movements in our sky are somewhat complicated (see Chapters 7 and 8). Consequently, the brightest of Jupiter’s moons are incomparably better for demonstrating the third Keplerian law quantitatively.

In the past when people assumed the Earth to be motionless, the easiest way to account for such a phenomenon was to imagine that the stars were embedded on a great rotating sphere.

A change in the latitude of the observer will show up as a shift in the displacement of the diurnal paths of the stars in the field of view of the exposure. For a displacement of 2 mm on an exposure taken with a camera lens of 135-mm focal length, a north-south displacement of 100 km is needed.
