The relationship is this: more mass = more gravity The Earth does not *weigh* more than the Moon. Earth has more *mass* than the Moon. Gravity on the Moon is about 1/6th that of Earth’s surface. Mass is an intrinsic property of an object that measures the amount of matter in that object. No matter where you go in the Universe, its mass will be the same. Weight is a force calculated from mass and *local* gravity. So you on Earth with a mass of 100 kg with have a weight of Newtons. On the Moon, you will *still* have a mass of 100 kg, but your weight will be /6 Newtons. If you want to “weigh” the Moon against Earth, or the Earth against the Sun, you will also have to reference whatever gravity exists at that frame of reference beyond the object in question.
