Recap what this text says about the Moon so a layperson can understand it. 

The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. The Moon was likely formed after a Mars-sized body collided with Earth.

Earth's Moon is the fifth largest of the 200+ moons orbiting planets in our solar system.
The Earth's Moon probably formed after Earth collided with a large object. It is the largest and brightest object in our night sky and the 5th-largest moon in our solar system. The Moon stabilizes Earth's climate and creates tides.
