Editing Variable-star designation (section)

{{Short description|Unique identifier given to variable stars}}
In [[astronomy]], a '''variable-star designation''' is a unique identifier given to [[variable star]]s.  It extends the [[Bayer designation]] format, with an identifying label (as described below) preceding the [[Latin language|Latin]] [[genitive case|genitive]] of the name of the [[constellation]] in which the star lies. The identifying label can be one or two [[Latin script|Latin]] letters or a ''V'' plus a number (e.g. V399). Examples are [[R Coronae Borealis]], [[YZ Ceti]], [[V603 Aquilae]]. (''See'' [[List of constellations]] ''for a list of constellations and the genitive forms of their names''.)
