Answer to Question 1

equator

Answer to Question 2

Titan was used to give gravitational assists to increase and decrease the semi-major axis of the probe's orbit. When Cassini passes Titan inside its orbit of Saturn, Cassini's orbital semi-major axis is decreased. When Cassini passes Titan outside its orbit of Saturn, Cassini's orbital semi-major axis is increased. Using this, Cassini's controllers are able to guide the spacecraft on a tour of Saturn's moon system even though the spacecraft doesn't have much of its own power.
