Question

Why does saturn exert more gravitational force than mars ?

Answer 1

Because Saturn is made of many gasses, saturns gravitational force is 10.44 m/s2 and it affects the spot surface

Answer 2

Mercury is the smallest planet, but its surface gravity is about the same as that of the larger Mars, because Mercury is denser. As such, Saturn is much larger than Earth, but not very dense, so the gravity on Saturn is roughly the same as on Earth. Mars: 0.38 G. Jupiter: 2.53 grams.
