The mass stays the same, only the weight changes.
Weight is a function of gravity so:
W=mg where W=weight, m=mass and g=gravitational acceleration.
An average giraffe weighs on Earth about 2,200lbs.
On the Moon is would weigh about 365.2lbs, whereas on Jupiter is would weigh about 5200.8lbs.
The mass will be the same on Jupiter and the Moon. The mass does not change.
The moon that is described as having the largest mass is Ganymede. This is one of the moons of Jupiter. Its mass is about 2.02 times that of Earth's moon.
The two Jovian planet satellites that are larger in size than mercury are Ganymede and Titan. Ganymede is the moon of Jupiter and Titan is the moon of Saturn.
Jupiter because it is larger and you can't stand on the sun.
The planet Mercury with a diameter of 3030 miles (4878 kilometers) is smaller than Jupiter's moon Ganymede (5276 km) as well as Saturn's moon Titan (5150 km). Jupiter's moon Callisto (4800 km) as also nearly the same size as Mercury.

Larger
The moon Io is the densest moon of Jupiter. You would weigh about 18.3% of what you weigh on Earth. Jupiter's largest moon, Ganymede, is the largest moon in the solar system, with a larger diameter than Mercury but with much less mass. Ganymede's larger diameter and low density mean you would weigh slightly less (14.6%) than on the Moon (about 16.6% of your weight on Earth).
The earth is larger than the moon (about 4 times the size)12,756km vs 3,476 km in diameter . Jupiter is 318 times the mass of earth. The gravitational pull of Jupiter is immense!

Since mass is constant no matter what the gravity is, the mass would stay 5kg if you're on the moon, Earth, the Sun, Jupiter, Mars, Pluto, etc...Answers.com
You don't weigh it, you compare it with standard mass units.
The largest moon in the Solar System is Ganymede, which is slightly larger (by volume) than the planet Mercury (Mercury is much denser, though, having about twice the mass of Ganymede). Ganymede is a satellite of Jupiter.
