Local location of nested child component relative to the blueprint it is in

Hi, Having a bit of trouble getting my head around how I should be approaching this.

I have

SceneRoot

Sphere

2 stars

The sphere rotates locally and moves through world space, but I need to record the change in position of the 2 stars relative to the SceneRoot. As the stars are children to the sphere, their “relative position” does not change. If I record world location the movement of the sphere through the game world is added.

Is there any way to see the change in position of the stars relative to the blueprint?
