Chamra Vortex asteroid

From Memory Alpha, the free Star Trek reference.

The Charma Vortex asteroid is one of millions of asteroids located in the Chamra Vortex. It has a breathable atmosphere.

In the 2360s, the criminal Croden hid his daughter, Yareth, in a stasis pod on this asteroid.

Later, in 2369, when Croden was to be returned to Rakhar by Odo on the USS Ganges, they took a detour to the Vortex and were chased into it by a Miradorn raider. Under the control of Croden, they landed the runabout on this asteroid where Croden retrieved his daughter, lying to Odo that it was a Changeling colony. (DS9: "Vortex")
