stellar designation

(identifiers for stars)

Stellar designation takes a number of forms, due to the increase over the ages of the number of stars known and studied. Newer methods generally aim at handling the larger number of known stars. Now, there are many stars for which older designations are used, with newer designations for more recently discovered stars, which generally have a dimmer apparent magnitude.

A few stars have traditional names. Bayer designation and Flamsteed designation were two methodical approaches introduced after telescopes came into use. Designators have come to be used for new discoveries by large surveys using modern research telescopes.

Variable stars have their own variable star designation.
