The average of Earth's aphelion and perihelion (nearest and farthest
distances from the sun) is  149,553,262 km.
The average of Saturn's aphelion and perihelion (nearest and farthest
distances from the sun) is  1,426,666,422 km.
That's about 4.6% less than 10-times Earth's number.
The difference is  6.887 x 10⁷ km .  (rounded)
