      Everything that has ‘weight’ (technically mass rather than weight) has gravity, and the heavier something is the stronger its gravity. So Jupiter does have gravity, but even though it is over 1300 times bigger (in volume) than Earth, it is actually only weighs 320 times as much. This is because Jupiter is mostly made of gas, rather than of rock like the Earth. This means that the gravity on Jupiter is only about 2.5 times stronger than on Earth.
