Answer:
Step-by-step explanation:
The commonly thought answer is rings, although I believe Jupiter has them. The other answer might be a large density. Jupiter has a large density, Saturn would float in a bathtub if it was large enough.
Jupiter has 7 sets of rings which were not discovered until 1979 when voyager went up. Saturn's rings are much more visible. In total there are 4 planets that have rings. The other two are Uranus and Neptune.
