Maybe you've seen it?

Our home, Earth, has one large moon. It's one of the largest moons in our solar system, relative to the diameter of its parent.

In fact, the moon is the largest of all, if you consider—as many astrophysicists do—Pluto and Charon a binary planet, or double planet, instead of a planet and a moon.

Our moon is the only natural body (besides Earth) on which humans have landed.

But give us time.
