Quark's moon
Quark's moon was, originally, a unspecificed moon sought for purchase by Quark, as a means of defining his own success, which he measured against his cousin , who owned his own moon. (, et al.)

When Quark began working with Gaila, working for Hagath as an arms dealer, Gaila assured him that by taking the job, "[i]n a year, you'll have your own moon," much to Quark's content. ()

In an alternate timeline, after the Federation relinquished control of Deep Space 9 to the Klingon Empire, Quark was finally able to purchase such a moon. His brother Rom maintained the facilities on the moon, keeping it from "falling out of orbit". ()
