Earth and its moon, "Luna"

You may be looking for the page for Earth's moon, Luna.

A moon is a generic name for a natural satellite that orbits a planet.

Moons may occur in all varieties concerning their number, form and size.
The two moons of Mars are tiny dead planetoids, whereas the Bajoran moon "Jeraddo" was a planet-sized M-class world, before it was transformed into a wasteland.

More massive moons may also strongly influence their primary planet, as they exert gravitational forces, which can define a planet's orbital period as well as its seasons, as is the case with Earth's moon, Luna.

In an alternate timeline, Quark was able to fulfill his dream and bought his own moon after selling his bar to his friend Morn.
