Distance from Earth to Saturn?
1277.42 x 10^6 km
1.2 Billion km
When Saturn and Earth are at aphelion (furthest from the Sun) and diametrically opposite each other, the distance can be as great as 1.66 billion 1.66 * 10^9) km
When Saturn is at perihelion and Earth at aphelion and they are on a line on the same side as the Sun the distance can shrink to 1.20 billion (1.20*10^9) km.
The difference between minimum and maximum distance to Saturn is more than 400 million km which is more than three AU (average distance of the Earth to the Sun) it takes light close to half an hour to travel there.
