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:
“Modern tourist guides have helped raised tourist expectations. And they have provided the nativesfrom Kaiser Wilhelm down to the villagers of Chichacestenangowith a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists stage.”
—Daniel J. Boorstin (b. 1914)
“Hey, you dress up our town very nicely. You dont look out the Chamber of Commerce is going to list you in their publicity with the local attractions.”
—Robert M. Fresco, and Jack Arnold. Dr. Matt Hastings (John Agar)
“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)
