Ok, bare with me for a moment. Just imagine the Earth being truly fixed while the rest of the universe revolves around the Earth. Stop it. Just suspend your disbelief for a second. Also, ignore the fact that there is nothing that we know of that would hold Earth in a fixed position. Just imagine that the Earth is truly fixed with everything else moving around it.
The result would be just the same as if the Earth is orbiting the sun.
Let me take my shirt of first, then I'll bear with you ...
You can also do this with the moon and every speck of dust that is in space anywhere. Even any subatomic particle. All you end up with is more math to figure things out for what you want to accomplish.
This does not prove that any one frame of reference is correct or incorrect.
In each case what we are doing mathematically is taking the frame of reference for a universe where the earth spins in orbit around the center of the solar system (of which the sun is the dominant mass) which spins in orbit around the center of the galaxy which meanders through time and space relative to the mass distribution\gravity distribution of the rest of the universe -- and transform that to any frame of reference of our choosing.
Thus in
every case the math involves the earth spinning in orbit around the sun. In terms of theory, the more parsimonious concept that still explains all the data is preferred, however this does not mean that it is necessarily correct or proved.
Where we can suggest an experiment to determine what frame of reference is correct we need to think outside the Newtonian box: we send a probe directly to the earth north (or south .. or both) pole; it has a nuclear clock, gyroscope and star observation capability so that it keeps oriented to stay stationary or match the spin of the earth (whichever is "true"). As it leaves the solar neighborhood the time frame will change (less mass around it) and the effect we know as dark matter\energy will raise it's head.
Prediction: that the spin of the universe relative to the earth will be different on the probe than on earth or the radioactive clock will need a different calibration than an identical one on earth.
We can also send an identical probe to ascend directly over the solar north (or south ... or both) pole, and use this to compare the amount of energy needed to maintain the probes in their relative positions and orientations.
Prediction: to "solar north" probe will need much less energy to maintain relative position and orientation than the "earth north" probe.
Enjoy.
