What is Uranus's distance from Saturn?
From average distances of Saturn (9.54 AU) and Uranus (19.22 AU) from their star Sun, the distance of Uranus from Saturn might vary from (the difference) 9.68 AU to (the sum) 28.76 AU..
The difference is nearly the distance, when they are on the same heliocentric longitudinal plane. The sum is nearly the distance, when this longitude differs by 180 deg. These positions relative to the Sun can be called longitudinal conjunction and longitudinal opposition, respectively.
