Here is a list of the 88 modern constellations by their area in the sky, measured in square degrees.
These areas are determined by constellation boundaries drawn up by Eugène Delporte in 1930 on behalf of the IAU and published in Délimitation scientifique des constellations (Cambridge University Press). Before Delporte's work, the precise boundaries of each constellation were only vaguely defined.
Delporte drew the boundaries along vertical and horizontal lines of right ascension and declination; however, he did so for the epoch B1875.0, which means that due to precession of the equinoxes, the borders on a modern star map (e.g., for epoch J2000) are already somewhat skewed and no longer perfectly vertical or horizontal. This skew will increase over the years and centuries to come. However, this does not change the area of any constellation.

- Notes
Famous quotes containing the words list of, list and/or area:
“The advice of their elders to young men is very apt to be as unreal as a list of the hundred best books.”
—Oliver Wendell Holmes, Jr. (18411935)
“Lastly, his tomb
Shall list and founder in the troughs of grass
And none shall speak his name.”
—Karl Shapiro (b. 1913)
“If you meet a sectary, or a hostile partisan, never recognize the dividing lines; but meet on what common ground remains,if only that the sun shines, and the rain rains for both; the area will widen very fast, and ere you know it the boundary mountains, on which the eye had fastened, have melted into air.”
—Ralph Waldo Emerson (18031882)
