My understanding is that the phenomenon of aberration does not affect the gravitational interaction between relatively moving bodies, whether such interaction be described from a Newtonian or General Relativistic perspective. Aberration is an observer-dependent phenomenon. But so is relativistic mass change. Consider observers on two relatively moving bodies. who each perceive the inertial mass of the other body to increase with velocity. Do such relatively moving observers also perceive a change in gravitational mass and if so, would they also perceive an increase in gravitational interaction? Or do special and general relativity conspire to leave this interaction unaffected, like aberration, by relative motion?
