Planets and Moons

What is the gravitational force on each of the planets, the moon, and the sun relative to Earth?

If the gravitational force on Earth is taken as 1, the comparative forces are:

Sun 27.9
Mercury 0.37
Venus 0.88
Moon 0.16
Mars 0.38
Jupiter 2.64
Saturn 1.15
Uranus 0.93
Neptune 1.22

Weight comparisons can be made by using this table. If a person weighed 100 pounds (45.36 kilograms) on Earth, then the weight of the person on the moon would be 16 pounds (7.26 kilograms) or 100 x 0.16.
