Even then one needs Newton's absolute coordinate frame of reference that he called the "fixed" stars, there being no other reference available, and we need to take into account Earth's precession.

So why doesn't the calculation method that successfully accounts for Jupiter in the analysis of the orbits of the other planets work for Mercury?

T is for 2pi radians only. (v/c)^2 - delay, light aberration, ect. a = 1.75 arcsecs - deflection angle. 1.75 / 3600 / 360 = (v/c)^2; v = 350 km/s - CMB radiation. v - average star-sun velocity. Shapiro - (v/c)^2; simple Sagnac effect.

T1 = d(t=0)/c, light speed on Mars is c; and back: T2 = d(t=T1)/c; light speed on Earth is c; ====== v = 350 km/s - solar wind speed, not stars. |
