Does gravity bend around massive objects like light does?

[Stephanus]

Dear PF Forum,

I realize that there are 4 basic forces in our universe.
Two of them are gravity and electromagnetic force.

Electromagnetic travels at the speed of light.
And it seems that Gravity travels/propagates at the speed of light also.

Light is bent by gravity. What about gravity?
Is gravity bent by gravity?
In the picture above. Planet C will see star A1 as in position A2.
What about the gravity? Does C orbit the barycentre of A2-B-C, or the barycenter of A1-B-C?

Thanks

If you think about this, you will see that there's only one object and its real position is $A_1$ but as we know light path will change according to gravity of B planet. So we will see $A_1$ in $A_2$.Thats doesn't mean gravity bent.Only light bent and we different place the object so the answer will be $A_1$ B C.Objects move according to space time curvature.If you think real $A_1$ is in $A_2$ that causes different curvature and movement.

I don't think gravity is deflected this way, but gravitational waves might be.

Given that the reason for light being bent is because they follow the geodesic of a distorted spacetime, I would think gravity waves would do the same. It would strike me as peculiar if they somehow traveled through spacetime in a special manner independent of the distortion.
