Fortunately for us, there are no known stars in the galaxy that are moving at close to the speed of light, nor are there any likely to make a close encounter with Jupiter, making the combination of these highly unlikey indeed. It is surely much more likely (though still highly unlikely) to be the fast star itself that causes the crisis for the solar system, not Jupiter after being catapulted by the star.
