Why is Jupiter disimilar to Saturn although their chemical composition is same?

Question

Both the gas giant planets jupiter and saturn comprise of hydrogen and helium and yet unlike jupiter saturn doesnt have colour patterns.

Answer 1

their atmosphere's chemical composition isn't exactly same..

also as Jupiter has stronger gravitational field it attracts much of the spatial dust ans asteroids and thus appears red to us

also Jupiter is almost twice as large as Saturn

Answer 2

Saturn does have colour patterns, they are not that dissimilar actually, Jupiter is larger but both are gas Giants.

Answer 3

jupiter is similar to saturn although chemical composition is same because the rings of saturn are made from ice particles which act like a prism and give it the seven colours.jupiter has rings which contain huge boulders.

Answer 4

Amongst the 'solar' planets the pair Jupiter -Saturn are the most similar. Both are true gaseous planets.

They are both the largest in the family. Saturn is 85.5% of Jupiter's size. Chemically they are similar. Rotation periods too are closeby with 10 hrs approximately.

Dissimilarites too are glaring. First, Jupiter is approximately quarter of Earth's (densest in Solar system) density; Saturn is almost half of Jupiter's and is the only planet with less than water's density. One reason may be, Jupiter has a much bigger solid core and Saturn has very small core. Jupiter may have attained a certain degree of 'core consolidation' which the other smaller planet (Saturn) couldn't. Perhaps there is critical mass above which such a process is set into motion for a gaseous planet. This aspect needs to be researched further, under 'Planetary internal mechanics'.

Next, Saturn is the only planet with an extensive ring system (A thin ring not easily visible was proposed for Uranus following observations) as an extension of its equator. May be one of its satellites strayed too close and got shattered to dust that is revolving in the form of rings.

In spite of visible odditites of saturn both are very similar.
