On December 25,2004 , the Huygens probe separated from the Cassini spacecraft orbiting Saturn and began a 22 day journey to Saturn's. moon Titan, on whose surface it landed. It is useful to know that Titan is 1.22×10³ km from the center of Saturn and has a mass of 1.35×10²³ kg and a diameter of 5150 km. The mass of Saturn is 5.68×10²³ kg. At what distance from Titan should the gravitational pull of Titan just balance the gravitational pull of Saturn? Express your answer with the appropriate units.
