Unfortunately, this leads to the problem of the
energy of the orbit changing due to the non-central
nature of the resulting force.
In Newtonian physics, any force with a finite propagation sp=ADeed
would be subjected to aberration as seen from a moving objec=ADt.
In the case of a planet orbiting the Sun, that would imply
a small component of the force in the direction of motion
which would slowly increase the speed of the planet, moving =ADit
into a larger orbit. And that would violate the principle o=ADf
conservation of energy.

I suppose an upgrade to SRT would take care of that, right?
