Problem with the Orbital Precession predicted by the Relativistic Acceleration equation used in the JPL D440-D441 Ephemerides - please advise

It helps to be clear at the outset what the effect of different exotic accelerations terms is upon orbit rotation. Assuming $m<<M$ and Newtonian Elliptical Orbits we have Specific Angular ...

NOTE There are some errors in this answer but I will leave it posted for now as it contains definitions and sources used in my other (shorter) answer. In the question I overlooked the fact that $\...

Problem with the Orbital Precession predicted by the Relativistic Acceleration equation used in the JPL D440-D441 Ephemerides - please advise

If you switch to polar coordinates and use the classical Newtonian gravitation of $GM/r^2$ (inwards) you get a centrifugal term of $v^2/r$ (outwards) Since these two terms must cancel out for a ...

Is there an optimum orbit for a Hipparcos/Gaia-like parallax observatory

It may be the Jupiter-Sun L2 point. There is not light from Sun. This provides a minimum low temperature. This is necessary for a minimum noise and for a greater sensitivity. There is acceptable ...
