Gravity on Jupiter: Jupiter is the largest and most massive planet in the Solar System. Its mean radius, at 69,911 Â± 6 km, makes it 10.97 the times the size of Earth, while its mass (1.8986Ã1027 kg) is the equivalent of 317.8 Earths.
Although Saturn is much larger than Earth, its surface gravity is only a little more than the surface gravity on Earth. This is because Saturn is made up of gases and is not solid like Earth. This makes Saturn very light for its size. Actually, Saturn has the lowest density of all the planets in our Solar System, even lower than the density of water.
