The weight of an object on the moon will be 1/6th of the weight of the object on earth. This is because the value of acceleration due to gravity on the moon is one-sixth of its value on the earth. The reason behind the difference in the gravitational pull on both the planets is the difference between the mass and radius of the moon and the earth. The mass and radius of the moon are less than that of the earth. That's why the acceleration due to gravity is less on the moon, which make an object feels lighter on the moon i.e. one-sixth of the weight on the earth.
