How far is Titan from the Sun in astronomical units? You will actually be computing the mean distance to Saturn, since Titan is in its orbit. When Titan is on Saturn's side closest to the Sun, it will be closer than the mean; when it is on the opposite side, it will be much farther.

HINT:
1. Use the distance given in the table and determine the distance to Titan in astronomical units.
2. One astronomical unit equals 149,600,000 kilometers.
3. Assume the orbits of Mars, the Saturn/Titan system and Earth are circular rather than elliptical about the sun.

A) 0.954 a.u.

B) 9.54 a.u.

C) 95.4 a.u.

D) 1.05 a.u.
