El-Gatark

El-Gatark was the site of a battle between the USS Valiant and a Cardassian battle cruiser in the early days of the Dominion War. It is close to the border between the Federation and the Cardassian Union. (DS9: "Valiant")

Like Sybaron, it is unknown if El-Gatark is a star, a system, a planet or another type of astronomical phenomena.
