Siderial vs Mean Solar is a direct result of the Earth orbiting the Sun. I have to take that into account when I compute a satellite orbit (especially when I use a stellar reference for postion and attitude)
If you are going to claim that you take *sidereal* effects into consideration when calculating orbits, at least learn to spell the term correctly. I pointed that out to you before and you look like a fool claiming to consider the effect while misspelling it twice.
Unfortunately for you, *sidereal* time is a consideration for calculating orbits no matter which model you use (heliocentric or geocentric). *Sidereal* time must be invoked because the relative geometric motion between the earth and the sun is the same no matter which model you use. Ernst Mach proved that over 100 years ago. The difference between mean solar time and *sidereal* time has been known for over 2,000 years and is the same in either a heliocentric or a geocentric model. To imply otherwise is either completely dishonest or totally ignorant.
I wonder if the Earth had a greater eccentricity of orbit, if thinkers of old would have been able to figure out astronomical truths sooner?
