QUESTION:
How close will Cassini fly to Saturn's cloud tops?

ANSWER from FAQ on June 11, 1999:
Upon reaching Saturn, Cassini will swing close to the planet, to an
altitude only one-sixth the diameter of Saturn itself (about 20,000 km).
This will begin the first of more than five dozen orbits during its
four-year mission, and it's the closest that Cassini will approach the
planet.
