The moon is the fifth-largest satellite in the solar system in terms of size.
The gravitational force of the upper layer of the moon is 16.6 percent of the gravitational force of the earth. So a person who weighs 100 pounds on Earth will weigh 18.6 pounds on the moon.
The weight of the moon is about 61 percent of the weight of the earth.
