Here's how it works:
* Mass: The Moon has a large amount of mass, which is the amount of matter it contains.
* Gravity: Mass creates a force called gravity. Gravity attracts all objects with mass towards each other. The more massive an object is, the stronger its gravitational pull.
* Earth and the Moon: The Earth and the Moon exert gravitational forces on each other. This is why the Moon orbits the Earth and why we have tides on Earth.
In summary, the Moon has gravity because it has mass, and its gravity is what keeps it in orbit around the Earth.
