The average distance between Titan and Saturn is about 1.2 billion kilometers. Titan is the largest moon of Saturn, and is the only moon known to have a dense atmosphere. It is also the only celestial object other than the Earth on which we have found clear evidence of stable bodies of surface liquid.

Note that in the model on the left, the relative angle of the Saturn Rings and the Titan orbit is only approximate, and other moons of Saturn are not shown.
