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 that are strong enough to affect the stability of the inclination of the planet's rotation axis and thereby its seasons, as is the case with Earth's moon Luna.
Gaila was able to buy his own moon with the income he made from selling weapons. Quark was envious of this for years. In 2373, when Quark began selling weapons with Gaila and Hagath, his cousin told him that after a year of doing so, he would be able to buy his own moon. (DS9: "Civil Defense", "The Way of the Warrior", "Business as Usual") In an alternate timeline, Quark was able to fulfill his dream and bought his own moon after selling his bar to Morn. (DS9: "The Visitor")
