Survey-based Designator

(Mission-based Designator, Catalog-based Designator)
(astronomical object designators based on name of survey)

Astronomical objects are often designated a catalog indicator (an abbreviation) followed either by a number, sometimes indicating the order of discovery, or by a J Designator indicating position in the Celestial Sphere. Each survey, or discovery mission/project in effect produces a catalog, for which these indicators of its discovered objects reveal the mission that found them.

Extra Solar Planets are all relatively new discoveries and generally designated in this manner. A final number or letter suffix may indicate which planet of a planet-bearing system, or which star of a multi-star system.

See examples in the Catalogs/Surveys table.
