Procyon V
From Memory Alpha, the free Star Trek reference
Procyon V is the fifth planet in the Procyon system.
In one possible timeline of 26th century, the planet was engulfed in the expanding Delphic Expanse, and was the site of the historic battle, where the United Federation of Planets routed the Sphere Builders and forced them back into their transdimensional realm. (ENT: "Azati Prime")
