The gravitational force of a planet (or body in space) is directly related to its mass. Mercury is the planet with the least mass in the Solar System. Based on its size Mercury has only 1/3 of the gravitational force felt on Earth. Therefore, if you weigh 100-pounds on Earth, you would only be some 33 on Mercury's surface.

The gravity on Mercury is 38% of the gravity on Earth. A 100 pound person would weigh only 38 pounds on Mercury.
