"It's a small moon, but it's enough to live on."
Gaila's moon was a small moon owned by Quark's cousin, Gaila. He had been able to buy it with the profit he made selling weapons. (DS9: "Civil Defense", "The Way of the Warrior", "Business as Usual")
Quark often considered owning a moon, like Gaila, to be a benchmark towards finally becoming a success. (DS9: "The Visitor", "Body Parts")
