While an airplane is in flight, four forces act on it. Thrust is caused by the airplane's propellers pushing through the surrounding air, pulling the airplane forward. Drag is caused by the air smacking into the plane's surface, pushing it backward.

Our Sun undergoes slight orbital motion mostly due to the gravitational force exerted by Jupiter. If our solar system only contained Saturn, how would the Sun's orbital period differ?
