Zeta Gelis Cluster
From Memory Alpha, the free Star Trek reference
The Zeta Gelis Star Cluster is a region of space located 2.3 parsecs from the planet Zalkon.
In 2366, the USS Enterprise-D was conducting a routine survey of an uninhabited star system in the Zeta Gelis Cluster when they discovered an amnesic Zalkonian, who they called "John Doe". (TNG: "Transfigurations")
