Question
why is Jupiters  mass greater  than Saturns

Answer
Paul,
Scientists are still trying to understand this.  Theories about how planets are formed are currently being re-examined, because some of the exoplanets discovered around other star systems don't really jibe with our existing theories.

Here are a few links, to give you an idea of what astronomers are thinking these days:

I wish I could give you a better answer, but the truth is, no one really knows.

Keep Looking Up!

Expertise

I am not a professional astronomer by any means, but astronomy has been an interest of mine since childhood, and I am well-informed on the subject. If unable to answer someone`s question personally, I will know how to quickly find the answer online, because I keep myself informed about developments in the field and I know where to look for information.

Experience

I worked in an observatory for awhile at one point, doing various interesting things with a computer.
