List of constellations by area

Hydra - the largest constellation in area

A list of 88 modern constellations , ordered by their area in the sky, measured in square degrees .

Constellation boundaries, compiled by Joseph Delport in 1930 on behalf of the International Astronomical Union (IAU) and published in the Délimitation scientifique des constellations (Cambridge University Press). Prior to this, the boundaries of the constellations were "blurred." Delport drew borders along the vertical and horizontal lines of right ascension and declination; however, he did so for the B1875.0 era , which means that due to the precession, the borders on the modern starry sky map (for the J2000 era) are already somewhat distorted. This distortion increases over time, but in general the boundaries of the constellations are unchanged.
