What is the weight of the moon?

The moon has a mass of 7.35 x 10²² kilograms. It is only about 60 percent as dense as Earth, and as such, the moon's mass is only 1.2 percent of Earth's. Thus, it would take the mass of 81 moons to equal the mass of Earth.

Due to the significant difference in mass, the moon only exerts about 17 percent of the gravitational pull compared to the Earth. A person weighing 100 pounds on the surface of Earth would only weigh 17 pounds on the moon. The moon is the fifth-largest satellite in the solar system. With a diameter of 6,783.5 miles, it is about 27 percent of the size of Earth.
