Is mass movement influenced by the curvature of spacetime?

[TimeRip496]

Is the movement of a mass affected by its curvature in spacetime? For instance will a forward moving planet diverges from its original straight line path due to the curvature of spacetime cause by it?

Yes. If bodies interact gravitationally then all their masses will enter the EOMs. It is a difficult case to handle in current gravitational theories.

Sounds similar to "is the electron affected by its own electrical field?". I shudder at the thought of looking into such depths.

Where should it diverge towards? A spherical mass creates a symmetrical spacetime distortion, without any preferred direction.

The gravitational self-effect is the compression under it's own gravity, as all the point masses the planet consists of tend to diverge towards the center.
