Bayer designation | Another name of the star which combines a Greek letter with the possessive form of its constellation's Latin name. |
Etymology of common name |
Etymology of the common name. |

The table of navigational stars provides several types of information. In the first column is the identifying index number, followed by the common name, the Bayer designation, and the etymology of the common name. Then the star's approximate position, suitable for identification purposes, is given in terms of declination and sidereal hour angle, followed by the star's magnitude. The final column presents citations to the sources of the data, The American Practical Navigator and the star's entry at the SIMBAD database, a project of the Strasbourg Astronomical Data Center or CDS.

“For the elemental creatures go
About my table to and fro,
That hurry from unmeasured mind
To rant and rage in flood and wind....
