We all understand how they determine the existence of planets other than those within our solar system... they plot the "wobble" of a star and figure out what other bodies in that system causes such a "wobble".
AND so I wondered how much does our Sun wobble..does any one know?
I think our Sun must follow somewhat a spiral course thru space with it and the planets having a common center and have wondered where this "center" could be... does anyone understand what I am driving at and if so indicate where this center may be...
