The sun’s gravitation, which keeps the planets in their elliptical orbits, is not relative to the speed of light.
General relativity predicts that gravitational radiation should exist and propagate as a wave at lightspeed: a slowly evolving and weak gravitational field will produce, according to general relativity, effects like those of Newtonian gravitation.

Suddenly displacing one of two gravitoelectrically interacting particles would, after a delay corresponding to lightspeed, cause the other to feel the displaced particle's absence: accelerations due to the change in quadrupole moment of star systems, like the Hulse–Taylor binary have removed much energy (almost 2% of the energy of our own Sun's output) as gravitational waves, which would theoretically travel at the speed of light.

I thought Einstein’s conclusion was that if the sun’s mass suddenly vanished, the earth would fly off tangentially like a ball being twirled on a string if the string broke. There would be no lag, as if the gravitational “wave” had to travel the 93 million miles.
