Why does the moon have less gravity than the earth?

Second, the greater the mass of an object, the stronger the force of gravity. Themoon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact. Finally, "weight" is a measure of the gravitational pull between two objects.

 Then moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity. the bigger the planet or moon the more gravity.
