Nah, Jupiter is the heaviest planet of the solar system.
This question is harder than it might seem. The answer is: You would weigh less on both Venus and Mars. You would weigh more on Jupiter. As regards Saturn, you could weigh more or less depending where on the planet you were. For example, at Saturn's equator the effect of the planet's rotation would be enough to reduce your effective weight to less than your Earth weight.
Helium is more abundant on Jupiter than on Saturn. Jupiter has a higher concentration of helium in its atmosphere compared to other planets in the solar system, including Saturn.
Saturn has more moons than Venus. Saturn is second to Jupiter.
Jupiter is hotter than Saturn. Jupiter has extreme heat due to its strong internal heat source, while Saturn's atmosphere reflects and scatters more sunlight, resulting in cooler overall temperatures.
Jupiter
The gravitational pull from Jupiter to the sun is stronger than the gravitational pull from Saturn to the sun. This is because Jupiter is more massive than Saturn, so it exerts a greater gravitational force over larger distances.
You would weigh about 6.68 times more on Jupiter.
Saturn has massive rings where Jupiter's rings are much smaller. Saturn is also much smaller in size than Jupiter. Saturn is also farther away from the Sun than Jupiter. Saturn also has a different color to it than Jupiter does. Jupiter has the distinguishing feature of a large read storm while Saturn is more plain and uniform in appearance; a sort of yellow, brown mixture.
No, Saturn is known to have more moons than Jupiter, though most of these are tiny moonlets orbiting in Saturn's rings.
Saturn has the largest rings. Also if you could make a tub big enough Saturn could float in it
The weight of matter on any planet depends upon the gravitational force of that planet. Jupiter has more gravitational force than Earth, so anything (including chocolate) would weigh more there. (Jupiter has no true surface, so you could not weigh anything there.)
You would weigh about 2.3 times more on Jupiter than you would on earth, because of Jupiter's massive size. Your mass would remain the same though.
