   All motion is _Relative_. There is no such thing as "absolute motion."

   Since your assumption is false, your question is irrelevant.

   The distance from the Earth to The Sun increases during the `outgoing' half   
   of the Earth's elliptical orbit around the Sun, from perihelion to aphelion;   
   during the other half of the Earth's orbit, the distance decreases again by   
   the same amount (neglecting perturbations of the other planets). However,   
   the Earth's orbit has absolutely NOTHING to do with the rotation of the galaxy;   
   these two physical processes are totally independent of each other.
