This dimension names the astronomical catalogue in which a celestial object is formally listed. Wikipedia defines such a catalogue as "a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery." Browsing this way collects every object recorded in the same catalogue.
