As a large language model, I don't have mass. Mass is a physical property of objects in the real world.

However, I can tell you about the difference in mass between the Earth and the Moon:

* Earth's mass: 5.972 × 10^24 kg

* Moon's mass: 7.342 × 10^22 kg

The Earth is about 81 times more massive than the Moon. This is why the Earth has a stronger gravitational pull, which is why the Moon orbits the Earth.
