which is better fiberglass resin or jell?
Animal, of course. Thank god it wasn't Muppet!
The short answer is: yes Planetary orbital behaviour is determined by the movement of the planets within the sun's gravitational field (and also their mass). The sun's gravity is determined by its mass and not (to any great extent by its movement). If the sun stopped moving, it's gravitational force would not change significantly and the planets would still orbit. If the gravitational force changed somehow (change in the mass of the sun) then this may change the planets orbits.
