Saturn is approximately 9.5 AU from the sun, which is about 0.00015 light years.
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.
Jupiter is not even close to a light year from the sun. Jupiter is about 5.2 AU from the sun on average, which works out to about 43 light minutes.
Voyager 1 was able to perform measurements and establish the distance as 121 AU (18 billion km). This would make the distance about 0.0019 light years.
