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:
“Religious literature has eminent examples, and if we run over our private list of poets, critics, philanthropists and philosophers, we shall find them infected with this dropsy and elephantiasis, which we ought to have tapped.”
—Ralph Waldo Emerson (18031882)
“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)
“Self-esteem is the real magic wand that can form a childs future. A childs self-esteem affects every area of her existence, from friends she chooses, to how well she does academically in school, to what kind of job she gets, to even the person she chooses to marry.”
—Stephanie Martson (20th century)
