Gould designation
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 according to epoch 1875.0, so due to precession〔(【引用サイトリンク】 title=Astronomical Epoch )〕 some stars may now occur out of order.
Gould designations first appeared in Uranometria Argentina,〔(【引用サイトリンク】 title=URANOMETRIA ARGENTINA )〕〔(【引用サイトリンク】 title=Uranometria Argentina catalog of bright southern stars (Gould, 1879) )〕 a catalogue published in 1879 by Benjamin Apthorp Gould.〔(【引用サイトリンク】 title=Gould, Benjamin Apthorp )〕 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.
==List of constellations utilizing Gould star designations==
There are 66 constellations contained in Gould's numbering system (some of which also are covered partially or fully by Flamsteed numbers). Stars are listed in the appropriate lists for these constellation, as follows:
