Hello, I want to thank the many people who sent me e-mails, helping me to understand the relationship between a geosat's orbital period, and the length of a sidereal day. I see it now. For some reason, I thought that the Sun's position was "fixed," and the stars were moving (4 minutes per day). I obviously had it backwards (and what I thought made absolutely no scientific sense!). A have another question, though: Stars appear to "travel" from East to West from night to night. Satellites with inclinations of 90.000 degrees and less (there's a term for this, it's the opposite of "retrograde," but at the moment I can't remember it....) travel from West to East. Am I correct in thinking that this does not matter, that the only important detail is the orbital period? ------------------------------ Jonathan T.
