get_constellation

astropy.coordinates.get_constellation(coord, short_name=False, constellation_list='iau')[source]

Determines the constellation(s) a given coordinate object contains.

Parameters
coordastropy:coordinate-like

The object to determine the constellation of.

short_namebool

If True, the returned names are the IAU-sanctioned abbreviated names. Otherwise, full names for the constellations are used.

constellation_liststr

The set of constellations to use. Currently only 'iau' is supported, meaning the 88 “modern” constellations endorsed by the IAU.

Returns
constellationstr or str array

If coords contains a scalar coordinate, returns the name of the constellation. If it is an array coordinate object, it returns an array of names.

Notes

To determine which constellation a point on the sky is in, this precesses to B1875, and then uses the Delporte boundaries of the 88 modern constellations, as tabulated by Roman 1987.
