Gould designations for stars are similar to Flamsteed designations in the way that they number stars within a constellation in increasing order of right ascension. Each star is assigned an integer (starting at 1), followed by " G. " (or occasionally followed directly by a "G" without a space), and then the Latin genitive of the constellation it lies in. See 88 modern constellations for a list of constellations and the genitive forms of their names.
They were assigned according to the stars' positions in epoch 1875.0, and over time are affected by Precession of the Equinoxes.[1] Due to the star's proper motions or cpm., some stars may now occur out of order.
Gould designations first appeared in Uranometria Argentina,[2][3] a catalogue published in 1879 by Benjamin Apthorp Gould.[4] Many of these designations have fallen out of use, though for many relatively bright southern stars (which are too far south to bear Flamsteed designations), Gould numbers remain the only simple designations available without referring to cumbersome catalogue numbers.
