rare designator prefixes

(designator prefixes generally used for only a few objects)

These are prefixes used in designators of objects (e.g., stars or galaxies) that are not commonly seen for any large number of objects. An IAU initiative offers formalized designation formats with the aim of object-references that are and remain unique and traceable, but designator prefixes actually used for objects are ultimately chosen by those who write or talk about the objects, and they often choose something convenient to write and say, often shortening the prefix. Such designator prefixes in use include:

See also double star designation.
