survey-based designator

(designator, mission-based designator, catalog-based designator)
(astronomical object designators based on name of survey)

Astronomical objects are often designated by a catalog indicator (an abbreviation) followed either by a number, sometimes indicating the order of discovery, or by a J designator indicating position within 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. See examples in the "Catalogs/Surveys table".

Extra-solar planet designations are generally are built on the star's designation, often in this form. Final lower-case letters, b, c, etc., indicates planets. Multi-star systems similarly use a star designation with a final upper-case letter, A, B, etc., to indicate which star.
