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.
Without getting too bogged down in the math, we can see that this leads to a surprising result. Take the most massive planet in the solar system, Jupiter, which tips the scales at 316 times the mass of the Earth. You might imagine you would weigh 316 times as much there as here.
