Procyon (also known as Procyon A or Alpha Canis Minoris A) is a star (spectral class F), along with a companion star named Phardos, located in the Procyon star system about 3.49 parsecs (11.4 light-years) from Earth, where it is visible in the constellation of Canis Minor. (ST references: Star Fleet Technical Manual, Spaceflight Chronology)

On several occasions in 2364, viewscreen readouts aboard the USS Enterprise-D showed the location of Procyon A, in the form of charts from the Enterprise library computer. (TNG episodes: "The Naked Now", "The Last Outpost", "Conspiracy")

The Chronology depicted Procyon A's name and distance from Earth on star chart illustrations, but since it is a "real" star system, modern scientists know a few things about its makeup that weren't in its Star Trek mentions.
