If so, then the orbit of the Earth's plane must be centered around where the Sun was located 8.3 minutes ago (78,186 miles from its present location). Yet is that what we observe??

The Earth/Sun SYSTEM is moving.

Its been fun, but I am way up past my bedtime. :-) See you tomorrow evening. Have a great night!

"The Earth/Sun SYSTEM is moving."

Indeed. Observing orbits would be pointless (in the scheme of determining the speed of Gravity) if our System was stationary instead of moving around at 157 miles per second.
