It depends on the gravitational pull of the planet. So the more massive the planet, the the greater the gravitational pull. Although its not necessarily the case that the size of an astronomical body relates to how much mass it contains.

For instance Neutron stars are much more massive than our sun, but are also much smaller. Black holes are the most massive objects in the universe and exert the most gravity, but their size is reduced to a singularity.

With planets on the other hand, size does tend to relate to mass, so the bigger the planet, the more gravity it exerts. So those who have said Jupiter in answer to your question are correct within the limits of our solar system. Extra-solar planets much larger than Jupiter, however, have been discovered around other stars.

The largest Extra-solar planet yet discovered is around 430 million kilometers from the star HD 168443 and is 17 times the size of Jupiter. So its likely that it would have the strongest gravitational field of any planet yet discovered, therefore you would weigh most on it.

Remember that surface gravity doesn't just depend on mass, but the radius of the planet too. Remember, the distance you are from the centre of mass helps to determine the gravitational attraction.

Surface Gravity = Gm/r^2
where G is the gravitational constant, m is the mass, and r is the radius of the object.

Surface gravities:
Mercury: 0.38
Venus: 0.9
Earth: 1 ... lol
Mars: 0.4
Jupiter: 2.35
Saturn: 1.38
Uranus: 0.89
Neptune: 1.1

So yes. Jupiter is the place were you would weigh the most.

I was going to say Mars ,because of the choco calories and all that sh ite,but i think that the planet with the greatest gravitational pull will provide the answer- what ever planet that is.We probally weigh the same no matter what planet we are on but i would imagine it would take a brave bit of holding down a weighing scales on a gravity free planet to find the answer.you know im the daddy,give me the points,this is your captain speaking,move along folks nothing to see here.United for the treble.

If you could stand on what looks like its surface, then you would weigh the most on Jupiter. Your weight at the surface of a planet is a function of your mass, the planet's mass, and your distance from the center of the planet (i.e., the diameter of the planet, if you're on the surface). Earth is the densest of the planets, but it's not very big. Jupiter is much more massive and not as dense, but still fairly dense, so you would weigh about 5 times as much on its surface than you do on Earth.

Size isn't everything; Saturn is the second largest planet (after Jupiter), but it isn't dense. It's actually less dense than water (the Earth is about 5.5 times as dense as water), and if you could stand on the surface of Saturn you would weigh only about 2% more than you do on Earth.

The more massive the planet the more you'll weigh. I think Jupiter is most massive in our solar system since it's a gas ball you couldn't stand on a bathroom scale. You would be crushed by gravitational force though.

Planet earth has a gravity and you would weigh the most. The planet mars has no gravity and you'll have to wear heavy boots but even then you'll bounce a bit. Jupiter.. you'll be gassed and suffocated. Venus..you'll be stir fried before you get there.

You will be heaviest on the planet which has the greatest surface gravity. Jupiter has a great mass and is very dense. You will be heaviest on Jupiter.
