Veloz Prime

From Memory Alpha, the free Star Trek reference

Veloz Prime is a planet inside the Demilitarized Zone and the former site of a Cardassian colony. In 2373, the Maquis, led by Michael Eddington, detonated three stratosheric torpedoes laden with cobalt diselenide in Veloz Prime's atmosphere. The nerve agent spread across the planet, forcing the Cardassians to evacuate. The Maquis settled the planet shortly after. (DS9: "For the Uniform")

Is is unclear if Veloz Prime is a part of the Velos system.
